# wee_import
Some WeeWX users will have historical data from another source (e.g., other weather station software or a manually compiled file) which they wish to import into WeeWX. Such data can, depending upon the source, be imported using the `wee_import` utility.
The `wee_import` utility supports importing observational data from the following sources:
* a single [Comma Separated Values (CSV)](wee_import-csv.md) format file
* the historical observations of a [Weather Underground](wee_import-wu.md) personal weather station
* one or more [Cumulus](wee_import-cumulus.md) monthly log files
* one or more [Weather Display](wee_import-wd.md) monthly log files
* one or more [WeatherCat](wee_import-weathercat.md) monthly .cat files

`wee_import` requires a second configuration file, the import configuration
file, in addition to the standard WeeWX configuration file. The import
configuration file specifies the import type and various options associated
with each type of import. The import configuration file is specified using the
mandatory `--import-config` option. How you construct the import configuration
file is up to you; however, the recommended method is to copy one of the
example import configuration files located in the `/home/weewx/util/import` or
`/etc/weewx/import` directory as applicable, modify the configuration options
in the newly copied file to suit the import to be performed and then use this
file as the import configuration file.
Following is the definitive guide to the options available in the import
configuration file. Default values are provided for a number of options,
meaning that if they are not listed in the import configuration file at all
`wee_import` will pick sensible values. When the documentation below gives a
default value this is the value that will be used if the option is omitted.
### `source`{#import_config_source}
The `source` option determines the type of import to be performed by
`wee_import`. The option is mandatory and must be set to one of the following:
* `CSV` to import from a single CSV format file.
* `WU` to import from a Weather Underground PWS history
* `Cumulus` to import from one or more Cumulus monthly log files.
* `WD` to import from one or more Weather Display monthly log files.
* `WeatherCat` to import from one or more WeatherCat monthly .cat files.
There is no default.
## [CSV]
The `[CSV]` section contains the options controlling the import of
observational data from a CSV format file.
### `file`{#csv_file}
The file containing the CSV format data to be used as the source during the
import. Include full path and filename.
There is no default.
### `source_encoding`{#csv_encoding}
The source file encoding. This parameter is optional and should only need be
used if the source file uses an encoding other than UTF-8 or an ASCII
compatible encoding. If used, the setting used should be a <a href="https://docs.python.org/3/library/codecs.html#standard-encodings">Python Standard Encoding</a>.
The default is `utf-8-sig`.
### `delimiter`{#csv_delimiter}
The character used to separate fields. Default is `,` (comma).
### `decimal`{#csv_decimal}
The character used as the decimal point in the source files. A full stop is
frequently used, but it may be another character. This parameter must be
included in quotation marks.
The default is `'.'`.
### `interval`{#csv_interval}
Determines how the time interval (WeeWX archive table field `interval`)
between successive observations is derived. The interval can be derived by one
of three methods:
* The interval can be calculated as the time, rounded to the nearest minute, between the date-time of successive records. This method is suitable when the data was recorded at fixed intervals and there are NO missing records in the source data. Use of this method when there are missing records in the source data can compromise the integrity of the WeeWX statistical data. Select this method by setting `interval = derive`.
* The interval can be set to the same value as the `archive_interval` setting under `[StdArchive]` in `weewx.conf`. This setting is useful if the data was recorded at fixed intervals but there are some missing records and the fixed interval is the same as the `archive_interval` setting under `[StdArchive]` in `weewx.conf`. Select this method by setting `interval = conf`.
* The interval can be set to a fixed number of minutes. This setting is useful if the source data was recorded at fixed intervals but there are some missing records and the fixed interval is different to the `archive_interval` setting under `[StdArchive]` in `weewx.conf`. Select this method by setting `interval = x` where `x` is an integer number of minutes.
If the CSV source data records are equally spaced in time, but some records are missing, then a better result may be achieved using `conf` or a fixed interval setting.
The default is `derive`.
### `qc`{#csv_qc}
Determines whether simple quality control checks are applied to imported data. Setting `qc = True` will result in `wee_import` applying the WeeWX `StdQC` minimum and maximum checks to any imported observations. `wee_import` quality control checks use the same configuration settings, and operate in the same manner, as the [_StdQC_](../reference/weewx-options/stdqc.md) service. For example, for minimum/maximum quality checks, if an observation falls outside of the quality control range for that observation, the observation will be set to `None`. In such cases you will be alerted through a short message similar to:
```
2016-01-12 10:00:00 AEST (1452556800) record value 'outTemp' 194.34 outside limits (0.0, 120.0)
```
As derived observations are calculated after the quality control check is applied, derived observations are not subject to quality control checks. Setting `qc = False` will result in `wee_import` not applying quality control checks to imported data.
The default is `True`.
### `calc_missing`{#csv_calc_missing}
Determines whether any missing derived observations will be calculated from the imported data. Setting `calc_missing = True` will result in `wee_import` using the WeeWX `StdWXCalculate` service to calculate any missing derived observations from the imported data. Setting `calc_missing = False` will result in WeeWX leaving any missing derived observations as `None`. See [_[StdWXCalculate]_](../reference/weewx-options/stdwxcalculate.md) for details of the observations the `StdWXCalculate` service can calculate.
The default is `True`.
### `ignore_invalid_data`{#csv_ignore_invalid_data}
Determines whether invalid data in a source field is ignored or the import aborted. If invalid data is found in a source field and `ignore_invalid_data` is `True` the corresponding WeeWX destination field is set to `None` and the import continues. If invalid data is found in a source field and `ignore_invalid_data` is `False` the import is aborted.
The default is `True`.
### `tranche`{#csv_tranche}
To speed up database operations imported records are committed to database in groups of records rather than individually. The size of the group is set by the `tranche` parameter. Increasing the `tranche` parameter may result in a slight speed increase but at the expense of increased memory usage. Decreasing the `tranche` parameter will result in less memory usage but at the expense of more frequent database access and likely increased time to import.
The default is `250` which should suit most users.
### `UV_sensor`{#csv_UV}
WeeWX records a `None/null` for UV when no UV sensor is installed, whereas some weather station software records a value of 0 for UV index when there is no UV sensor installed. The `UV_sensor` parameter enables `wee_import` to distinguish between the case where a UV sensor is present and the UV index is 0 and the case where no UV sensor is present and UV index is 0. `UV_sensor = False` should be used when no UV sensor was used in producing the source data. `UV_sensor = False` will result in `None/null` being recorded in the WeeWX archive field `UV` irrespective of any UV observations in the source data. `UV_sensor = True` should be used when a UV sensor was used in producing the source data. `UV_sensor = True` will result in UV observations in the source data being stored in the WeeWX archive field `UV`.
The default is `True`.
### `solar_sensor`{#csv_solar}
WeeWX records a `None/null` when no solar radiation sensor is installed, whereas some weather station software records a value of 0 for solar radiation when there is no solar radiation sensor installed. The `solar_sensor` parameter enables `wee_import` to distinguish between the case where a solar radiation sensor is present and solar radiation is 0 and the case where no solar radiation sensor is present and solar radiation is 0. `solar_sensor = False` should be used when no solar radiation sensor was used in producing the source data. `solar_sensor = False` will result in `None/null` being recorded in the WeeWX archive field `radiation` irrespective of any solar radiation observations in the source data. `solar_sensor = True` should be used when a solar radiation sensor was used in producing the source data. `solar_sensor = True` will result in solar radiation observations in the source data being stored in the WeeWX archive field `radiation`.
The default is `True`.
### `raw_datetime_format`{#csv_raw_datetime_format}
WeeWX records each record with a unique unix epoch timestamp, whereas many weather station applications or web sources export observational data with a human-readable date-time. This human-readable date-time is interpreted according to the format set by the `raw_datetime_format` option. This option consists of [Python strptime() format codes](https://docs.python.org/2/library/datetime.html#strftime-and-strptime-behavior) and literal characters to represent the date-time data being imported.
For example, if the source data uses the format 23 January 2015 15:34 the appropriate setting for `raw_datetime_format` would be `%d %B %Y %H:%M`, 9:25:00 12/28/16 would use `%H:%M:%S %m/%d/%y`. If the source data provides a unix epoch timestamp as the date-time field the unix epoch timestamp is used directly and the `raw_datetime_format` option is ignored.
The default is `%Y-%m-%d %H:%M:%S`.
!!! Note
`wee_import` does not support the construction of the unique record date
time stamp from separate date and time fields, rather the date-time
information for each imported record must be contained in a single
field. CSV data containing separate date and time fields may require
further manual processing before they can be imported.
### `rain`{#csv_rain}
The WeeWX `rain` field records rainfall that was recorded in the preceding archive period, so for a five-minute archive period the `rain` field in each archive record would contain the total rainfall that fell in the previous five minutes. Many weather station applications provide a daily or yearly total. `wee_import` can derive the WeeWX `rain` field in one of two ways:
* If the imported rainfall data is a running total then `wee_import` can derive the WeeWX `rain` field from successive totals. For this method use `rain = cumulative`.
* If the imported rainfall data is a discrete value per date-time period then `rain = discrete` should be used.
!!! Note
`wee_import` only supports cumulative rainfall data that resets on a
midnight boundary, cumulative rainfall data that resets at some other
time; e.g., 9am, is not supported. In such cases the rainfall data will
need to be converted to either reset on a midnight boundary or a discrete
value per date-time period and `rain = discrete` used. The former may be
possible by selecting another rainfall field (if available) in the source
data, otherwise it will require manual manipulation of the source data.
### `wind_direction`{#csv_wind_direction}
WeeWX records wind direction in degrees as a number from 0 to 360 inclusive (no wind direction is recorded as `None/null`), whereas some data sources may provide wind direction as number over a different range (e.g., -180 to +180) or may use a particular value when there is no wind direction (e.g., 0 may represent no wind direction and 360 may represent a northerly wind, or -9999 (or some similar clearly invalid number) to represent there being no wind direction). `wee_import` handles such variations in data by defining a range over which imported wind direction values are accepted. Any value outside of this range is treated as there being no wind direction and is recorded as `None/null`. Any value inside the range is normalised to the range 0 to 360 inclusive (e.g., -180 would be normalised to 180). The `wind_direction` option consists of two comma separated numbers of the format lower, upper where lower and upper are inclusive. The operation of the `wind_direction` option is best illustrated through the following table:
<table id='wind_direction' class="indent" style="width:80%;text-align: center">

### `[[FieldMap]]`{#csv_fieldmap}
The `[[FieldMap]]` stanza defines the mapping from the source data fields to WeeWX archive fields. The map consists of one row per field being imported using either of the following formats:
```
weewx_archive_field_name = csv_field_name, weewx_unit_name
```
or
```
weewx_archive_field_name = csv_field_name, text
```
Where:
* `weewx_archive_field_name` is a field name in the in-use WeeWX archive table schema
* `csv_field_name` is the name of a field from the CSV file
* `weewx_unit_name` is the WeeWX unit name of the units used by `csv_field_name`
* `text` is the literal word text
This mapping allows `wee_import` to take a source data field, do the appropriate unit conversion and store the resulting value in the appropriate WeeWX archive field. Source data text fields may be mapped to a WeeWX text archive field by using the second form of the field map entry where the literal `text` is used in place of a WeeWX unit name. A mapping is not required for every WeeWX archive field (e.g., the source may not provide inside temperature so no `inTemp` field mapping is required) and neither does every CSV field need to be included in a mapping (e.g., the source data field `monthrain` may have no use if the source data field `rain` provides the data for the WeeWX archive `rain field). Unused field mapping lines will not be used and may be omitted.
!!! Note
Importing of text data into text fields in the WeeWX archive is only supported for WeeWX archive fields that have been configured as text fields. Refer to the Wiki page [Storing text in the database](https://github.com/weewx/weewx/wiki/Storing-text-in-the-database) for details.
If the source data includes a field that contains a WeeWX unit system code (i.e. the equivalent of the WeeWX `usUnits` field such as may be obtained from WeeWX or wview data) then this field can be mapped to the WeeWX `usUnits` field and used to set the units used for all fields being imported. In such cases the `weewx_unit_name` portion of the imported fields in the field map is not used and can be omitted.
For example, source CSV data with the following structure:
```
date_and_time,temp,humid,wind,dir,rainfall,rad,river
23 May 2018 13:00,17.4,56,3.0,45,0.0,956,340

```
where `temp` is temperature in Celsius, `humid` is humidity in percent, `wind` is wind speed in km/h, `dir` is wind direction in degrees, `rainfall` is rain in mm, `rad` is radiation in watts per square meter and `river` is river height in mm might use a field map as follows:
```
[[FieldMap]]
dateTime = date_and_time, unix_epoch
outTemp = temp, degree_C
outHumidity = humid, percent
windSpeed = wind, km_per_hour
windDir = dir, degree_compass
rain = rainfall, mm
radiation = rad, watt_per_meter_squared
```
If the same source CSV data included a field `unit_info` that contains WeeWX unit system data as follows:
```
date_and_time,temp,humid,wind,dir,rainfall,rad,river,unit_info
23 May 2018 13:00,17.4,56,3.0,45,0.0,956,340,1
23 May 2018 13:05,17.6,56,1.0,22.5,0.4,746,341,16
```
then a field map such as the following might be used:
```
[[FieldMap]]
dateTime = date_and_time, unix_epoch
usUnits = unit_info
outTemp = temp
outHumidity = humid
windSpeed = wind
windDir = dir
rain = rainfall
radiation = rad
```
!!! Note
Any WeeWX archive fields that are derived (e.g., `dewpoint`) and for which there is no field mapping may be calculated during import by use of the [`calc_missing`](#csv_calc_missing) option in the `[CSV]` section of the import configuration file.
!!! Note
The `dateTime` field map entry is a special case. Whereas other field map entries may use any supported WeeWX unit name, or no unit name if the `usUnits` field is populated, the `dateTime` field map entry must include the WeeWX unit name `unix_epoch`. This is because `wee_import` uses the [raw_datetime_format](#csv_raw_datetime_format) config option to convert the supplied date-time field data to a Unix epoch timestamp before the field map is applied.
## [WU]
The `[WU]` section contains the options relating to the import of observational data from a Weather Underground PWS history.
### `station_id`{#wu_station_id}
The Weather Underground weather station ID of the PWS from which the historical data will be imported.
There is no default.
### `api_key`{#wu_api_key}
The Weather Underground API key to be used to obtain the PWS history data.
There is no default.
!!! Note
The API key is a seemingly random string of 32 characters used to access the new (2019) Weather Underground API. PWS contributors can obtain an API key by logging onto the Weather Underground internet site and accessing Member Settings. 16 character API keys used with the previous Weather Underground API are not supported.
### `interval`{#wu_interval}
Determines how the time interval (WeeWX database field `interval`) between successive observations is determined. This option is identical in operation to the CSV [interval](#csv_interval) option but applies to Weather Underground imports only. As a Weather Underground PWS history sometimes has missing records, the use of `interval = derive` may give incorrect or inconsistent interval values. Better results may be obtained by using `interval = conf` if the current WeeWX installation has the same `archive_interval` as the Weather Underground data, or by using `interval = x` where `x` is the time interval in minutes used to upload the Weather Underground data. The most appropriate setting will depend on the completeness and (time) accuracy of the Weather Underground data being imported.
The default is `derive`.
### `qc`{#wu_qc}
Determines whether simple quality control checks are applied to imported data. This option is identical in operation to the CSV [qc](#csv_qc) option but applies to Weather Underground imports only. As Weather Underground imports at times contain nonsense values, particularly for fields for which no data was uploaded to Weather Underground by the PWS, the use of quality control checks on imported data can prevent these nonsense values from being imported and contaminating the WeeWX database.
The default is `True`.
### `calc_missing`{#wu_calc_missing}
Determines whether any missing derived observations will be calculated from the imported data. This option is identical in operation to the CSV [calc_missing](#csv_calc_missing)" option but applies to Weather Underground imports only.
The default is `True`.
### `ignore_invalid_data`{#wu_ignore_invalid_data}
Determines whether invalid data in a source field is ignored or the import aborted. This option is identical in operation to the CSV [ignore_invalid_data](#csv_ignore_invalid_data) option but applies to Weather Underground imports only. The default is `True`.
### `tranche`{#wu_tranche}
The number of records written to the WeeWX database in each transaction. This option is identical in operation to the CSV [tranche](#csv_tranche) option but applies to Weather Underground imports only.
The default is `250` which should suit most users.
### `wind_direction`{#wu_wind_direction}
Determines the range of acceptable wind direction values in degrees. This option is identical in operation to the CSV [wind_direction](#csv_wind_direction) option but applies to Weather Underground imports only.
The default is `0, 360`.
## [Cumulus]
The `[Cumulus]` section contains the options relating to the import of observational data from Cumulus monthly log files.
### `directory`{#cumulus_directory}
The full path to the directory containing the Cumulus monthly log files to be imported. Do not include a trailing `/`.
There is no default.
### `source_encoding`{#cumulus_encoding}
The Cumulus monthly log file encoding. This option is identical in operation to the CSV [source_encoding](#csv_encoding) option but applies to Cumulus imports only.
The default is `utf-8-sig`.
### `interval`{#cumulus_interval}
Determines how the time interval (WeeWX database field `interval`) between successive observations is determined. This option is identical in operation to the CSV [interval](#csv_interval) option but applies to Cumulus monthly log file imports only. As Cumulus monthly log files can, at times, have missing entries, the use of `interval = derive` may give incorrect or inconsistent interval values. Better results may be obtained by using `interval = conf` if the `archive_interval` for the current WeeWX installation is the same as the Cumulus 'data log interval' setting used to generate the Cumulus monthly log files, or by using `interval = x` where `x` is the time interval in minutes used as the Cumulus 'data log interval' setting. The most appropriate setting will depend on the completeness and (time) accuracy of the Cumulus data being imported.
The default is `derive`.
### `qc`{#cumulus_qc}
Determines whether simple quality control checks are applied to imported data. This option is identical in operation to the CSV [qc](#csv_qc) option but applies to Cumulus imports only.
The default is `>True`.
### `calc_missing`{#cumulus_calc_missing}
Determines whether any missing derived observations will be calculated from the imported data. This option is identical in operation to the CSV [calc_missing](#csv_calc_missing) option but applies to Cumulus imports only.
The default is `True`.
### `separator`{#cumulus_separator}
The character used as the date field separator in the Cumulus monthly log file. A solidus (/) is frequently used, but it may be another character depending on the settings on the machine that produced the Cumulus monthly log files. This parameter must be included in quotation marks.
The default is `/`.
### `delimiter`{#cumulus_delimiter}
The character used as the field delimiter in the Cumulus monthly log file. A comma is frequently used, but it may be another character depending on the settings on the machine that produced the Cumulus monthly log files. This parameter must be included in quotation marks.
The default is `,`.
### `decimal`{#cumulus_decimal}
The character used as the decimal point in the Cumulus monthly log files. A full stop is frequently used, but it may be another character depending on the settings on the machine that produced the Cumulus monthly log files. This parameter must be included in quotation marks.
The default is `.`.
### `ignore_invalid_data`{#cumulus_ignore_invalid_data}
Determines whether invalid data in a source field is ignored or the import aborted. This option is identical in operation to the CSV [ignore_invalid_data](#csv_ignore_invalid_data) option but applies to Cumulus monthly log file imports only.
The default is `True`.
### `tranche`{#cumulus_tranche}
The number of records written to the WeeWX database in each transaction. This option is identical in operation to the CSV [tranche](#csv_tranche) option but applies to Cumulus monthly log file imports only.
The default is `250` which should suit most users.
### `UV_sensor`{#cumulus_UV}
Enables `wee_import` to distinguish between the case where a UV sensor is present and the UV index is 0 and the case where no UV sensor is present and UV index is 0. This option is identical in operation to the CSV [UV_sensor](#csv_UV) option but applies to Cumulus monthly log file imports only.
The default is `True`.
### `solar_sensor`{#cumulus_solar}
Enables `wee_import` to distinguish between the case where a solar radiation sensor is present and the solar radiation is 0 and the case where no solar radiation sensor is present and solar radiation is 0. This option is identical in operation to the CSV [solar_sensor](#csv_solar) option but applies to Cumulus monthly log file imports only.
The default is `True`.
### `[[Units]]`{#cumulus_units}
The `[[Units]]` stanza defines the units used in the Cumulus monthly log files. Units settings are required for `temperature`, `pressure`, `rain` and `speed`. The format for each setting is:
```
obs_type = weewx_unit_name
```
Where `obs_type` is one of `temperature`, `pressure`, `rain` or `speed` and `weewx_unit_name` is the WeeWX unit name of the units used by that particular `obs_type`. As Cumulus supports a different suite of possible units only a subset of the available WeeWX unit names can be used for some settings.
## [WD]
The `[WD]` section contains the options relating to the import of observational data from Weather Display monthly log files.
### `directory`{#wd_directory}
The full path to the directory containing the Weather Display monthly log files to be imported. Do not include a trailing `/`.
There is no default.
### `logs_to_process`{#wd_logs_to_process}
The Weather Display monthly log files to be processed. Weather Display uses multiple files to record each month of data. Which monthly log files are produced depends on the Weather Display configuration and the capabilities of the weather station. `wee_import` supports the following Weather Display monthly log files:
* MMYYYYlg.txt
* MMYYYYlgcsv.csv (csv format version of MMYYYYlg.txt)
* MMYYYYvantagelog.txt
* MMYYYYvantagelogcsv.csv (csv format version of MMYYYYvantagelog.txt)
* MMYYYYvantageextrasensorslog.csv
where MM is a one or two-digit month and YYYY is a four digit year
The format for the `logs_to_process` setting is:
```
logs_to_process = [lg.txt, | logcsv.csv, | vantagelog.txt, | vantagelogcsv.csv, | vantageextrasensorslog.csv]
```
!!! Note
The leading MMYYYY is omitted when listing the monthly log files to be processed using the `logs_to_process` setting. Inclusion of the leading MMYYYY will cause the import to fail.
!!! Note
The MMYYYYlgcsv.csv and MMYYYYvantagelogcsv.csv log files are CSV versions of MMYYYYlg.txt and MMYYYYvantagelog.txt respectively. Either the .txt or .csv version of these files should be used but not both.
The monthly log files selected for processing should be chosen carefully as the selected log files will determine the Weather Display data fields available for import. `wee_import` is able to import the following data from the indicated monthly log files:
* MMYYYYlg.txt/MMYYlgcsv.csv:
* `average wind speed`
* `barometer`
* `date and time`
* `dew point`
* `heat index`
* `outside humidity`
* `outside temperature`
* `rain fall`
* `wind direction`
* `wind gust speed`
* MMYYYYvantagelog.txt/MMYYYYvantagelogcsv.csv:
* `date and time`
* `soil moisture`
* `soil temperature`
* `solar radiation`
* `UV index`
* MMYYYYvantageextrasensorslog.csv:
* `date and time`
* `extra humidity 1`
* `extra humidity 2`
* `extra humidity 3`
* `extra humidity 4`
* `extra humidity 5`
* `extra humidity 6`
* `extra temperature 1`
* `extra temperature 2`
* `extra temperature 3`
* `extra temperature 4`
* `extra temperature 5`
* `extra temperature 6`
!!! Note
Whilst the above log files may contain the indicated data the data may only be imported subject to a suitable field map and in-use WeeWX archive table schema (refer to the [[[FieldMap]]](#wd_fieldmap) option).
The default is `lg.txt, vantagelog.txt, vantageextrasensorslog.csv`.
### `source_encoding`{#wd_encoding}
The Weather Display monthly log file encoding. This option is identical in operation to the CSV [source_encoding](#csv_encoding) option but applies to Weather Display imports only.
The default is `utf-8-sig`.
### `interval`{#wd_interval}
Determines how the time interval (WeeWX database field `interval`) between successive observations is determined. This option is identical in operation to the CSV [interval](#csv_interval) option but applies to Weather Display monthly log file imports only. As Weather Display log files nominally have entries at one minute intervals the recommended approach is to set `interval = 1`. As Weather Display monthly log files can, at times, have missing entries, the use of `interval = derive` may give incorrect or inconsistent interval values. If then `archive_interval` for the current WeeWX installation is 1 minute `interval = conf` may be used. In most cases the most appropriate setting will be `interval = 1`.
The default is `1`.
### `qc`{#wd_qc}
Determines whether simple quality control checks are applied to imported data. This option is identical in operation to the CSV [qc](#csv_qc) option but applies to Weather Display imports only.
The default is `True`.
### `calc_missing`{#wd_calc_missing}
Determines whether any missing derived observations will be calculated from the imported data. This option is identical in operation to the CSV [calc_missing](#csv_calc_missing) option but applies to Weather Display imports only.
The default is `True`.
### `txt_delimiter`{#wd_txt_delimiter}
The character used as the field delimiter in Weather Display text format monthly log files (.txt files). A space is normally used but another character may be used if necessary. This parameter must be included in quotation marks.
The default is `' '`.
### `csv_delimiter`{#wd_csv_delimiter}
The character used as the field delimiter in Weather Display csv format monthly log files (.csv files). A comma is normally used but another character may be used if necessary. This parameter must be included in quotation marks.
The default is `,`.
### `decimal`{#wd_decimal}
The character used as the decimal point in the Weather Display monthly log files. A full stop is frequently used but another character may be used if necessary. This parameter must be included in quotation marks.
The default is `.`.
### `ignore_missing_log`{#wd_ignore_missing_log}
Determines whether missing log files are to be ignored or the import aborted. Weather Display log files are complete in themselves and a missing log file will have no effect other than there will be no imported data for the period covered by the missing log file.
The default is `True`.
### `ignore_invalid_data`{#wd_ignore_invalid_data}
Determines whether invalid data in a source field is ignored or the import aborted. This option is identical in operation to the CSV [ignore_invalid_data](#csv_ignore_invalid_data) option but applies to Weather Display monthly log file imports only.
The default is `True`.
### `tranche`{#wd_tranche}
The number of records written to the WeeWX database in each transaction. This option is identical in operation to the CSV [tranche](#csv_tranche) option but applies to Weather Display monthly log file imports only.
The default is `250` which should suit most users.
### `UV_sensor`{#wd_UV}
Enables `wee_import` to distinguish between the case where a UV sensor is present and the UV index is 0 and the case where no UV sensor is present and UV index is 0. This option is identical in operation to the CSV [UV_sensor](#csv_UV) option but applies to Weather Display monthly log file imports only.
The default is `True`.
### `solar_sensor`{#wd_solar}
Enables `wee_import` to distinguish between the case where a solar radiation sensor is present and the solar radiation is 0 and the case where no solar radiation sensor is present and solar radiation is 0. This option is identical in operation to the CSV [solar_sensor](#csv_solar) option but applies to Weather Display monthly log file imports only.
The default is `True`.
### `ignore_extreme_temp_hum`{#wd_ignore_extreme_temp_hum}
Determines whether extreme temperature and humidity values are ignored. Weather Display log files record the value 255 for temperature and humidity fields if no corresponding sensor is present. Setting `ignore_extreme_temp_hum = True` will cause temperature and humidity values of 255 to be ignored. Setting `ignore_extreme_temp_hum = False` will cause temperature and humidity values of 255 to be treated as valid data to be imported.
The default is `True`.
!!! Note
Setting `ignore_extreme_temp_hum = False` will cause temperature and humidity values of 255 to be imported; however, these values may be rejected by the simple quality control checks implemented if `qc = True` is used.
### `[[Units]]`{#wd_units}
The `[[Units]]` stanza defines the units used in the Weather Display monthly log files. Weather Display monthly log files normally use Metric or US customary units depending on the _Log File_ setting under _Units_ on the _Units/Wind Chill_ tab of the Weather Display _Universal Setup_. In such cases the `units` configuration option may be set to `Metric` or `US` to select either Metric or US customary units.
There is no default.
It is also possible to individually specify the log file units used for `temperature`, `pressure`, `rain` and `speed`. The format for each setting is:
```
obs_type = weewx_unit_name
```
Where `obs_type` is one of `temperature`, `pressure`, `rain` or `speed` and `weewx_unit_name is the WeeWX unit name of the units used by that particular `obs_type. As Weather Display supports a different suite of possible units only a subset of the available WeeWX unit names can be used for some settings.
The preferred method for defining the Weather Display log file units is through the use of the `units` configuration option. When defining the import log file units either the `units` configuration option should be used or the individual `temperature`, `pressure`, `rain` and `>speed` units defined but not both. If both the `units` configuration option is defined as well as the individual `temperature`, `pressure`, `rain` and `speed` units defined the `units` configuration option takes precedence and all other units settings are ignored.
### `[[FieldMap]]`{#wd_fieldmap}
The `[[FieldMap]]` stanza defines the mapping from the Weather Display monthly log data fields to WeeWX archive fields. By default, imported Weather Display data is mapped to the corresponding WeeWX archive fields using a default field map. The default field map will likely suit most users; however, depending on the station capabilities and the in-use WeeWX database schema, a custom field map may be required if Weather Display monthly logs contain data from additional sensors that cannot be stored in the WeeWX archive using the default field map. A custom field map also makes it possible to limit the Weather Display monthly log data fields that are imported into WeeWX.
The field map consists of one row per field using the format:
```
weewx_archive_field_name = weather_display_field_name
```
Where `weewx_archive_field_name` is a field name in the in-use WeeWX archive table schema and `weather_display_field_name` is a Weather Display import field name. The available Weather Display import field names are listed in the table below.

</table>
A mapping is not required for every WeeWX archive field (e.g., the Weather Display monthly logs may not provide inside temperature so no `inTemp` field mapping is required) and neither does every Weather Display monthly log field need to be included in a mapping (e.g., the Weather Display monthly log field `soiltemp` may have no data as the station has no soil temperature probe).
!!! Note
Any WeeWX archive fields that are derived (e.g., `dewpoint`) and for which there is no field mapping may be calculated during import by use of the `calc_missing` option in the `[WD]` section of the import configuration file.
The example Weather Display import configuration file located in the `/home/weewx/util/import]` or the `/etc/weewx/import directory contains an example field map in the import configuration file comments.
There is no default.
## [WeatherCat]
The `[WeatherCat]` section contains the options relating to the import of observational data from WeatherCat monthly .cat files.
### `directory`{#wcat_directory}
The full path to the directory containing the year directories that contain the WeatherCat monthly .cat files to be imported. Do not include a trailing `/`.
There is no default.
### `source_encoding`{#wcat_encoding}
The WeatherCat monthly .cat file encoding. This option is identical in operation to the CSV [source_encoding](#csv_encoding) option but applies to WeatherCat imports only.
The default is `utf-8-sig`.
### `interval`{#wcat_interval}
Determines how the time interval (WeeWX database field `interval`) between successive observations is determined. This option is identical in operation to the CSV [interval](#csv_interval) option but applies to WeatherCat imports only. As WeatherCat monthly .cat files can, at times, have missing entries, the use of `interval = derive` may give incorrect or inconsistent interval values. Better results may be obtained by using `interval = conf` if the `archive_interval` for the current WeeWX installation is the same as the WeatherCat .cat file log interval, or by using `interval = x` where `x` is the time interval in minutes used in the WeatherCat monthly .cat file(s). The most appropriate setting will depend on the completeness and (time) accuracy of the WeatherCat data being imported.
The default is `derive`.
### `qc`{#wcat_qc}
Determines whether simple quality control checks are applied to imported data. This option is identical in operation to the CSV [qc](#csv_qc) option but applies to WeatherCat imports only.
The default is `True`.
### `calc_missing`{#wcat_calc_missing}
Determines whether any missing derived observations will be calculated from the imported data. This option is identical in operation to the CSV [calc_missing](#csv_calc_missing) option but applies to WeatherCat imports only.
The default is `True`.
### `decimal`{#wcat_decimal}
The character used as the decimal point in the WeatherCat monthly .cat files. This parameter must be included in quotation marks.
The default is `.`.
### `tranche`{#wcat_tranche}
The number of records written to the WeeWX database in each transaction. This option is identical in operation to the CSV [tranche](#csv_tranche) option but applies to WeatherCat imports only.
The default is `250` which should suit most users.
### `UV_sensor`{#wcat_UV}
Enables `wee_import` to distinguish between the case where a UV sensor is present and the UV index is 0 and the case where no UV sensor is present and UV index is 0. This option is identical in operation to the CSV [UV_sensor](#csv_UV) option but applies to WeatherCat imports only.
The default is `True`.
### `solar_sensor`{#wcat_solar}
Enables `wee_import` to distinguish between the case where a solar radiation sensor is present and the solar radiation is 0 and the case where no solar radiation sensor is present and solar radiation is 0. This option is identical in operation to the CSV [solar_sensor](#csv_solar) option but applies to WeatherCat imports only.
The default is `True`.
### `[[Units]]`{#wcat_units}
The `[[Units]]` stanza defines the units used in the WeatherCat monthly .cat files. Unit settings are required for `temperature`, `pressure`, `rain` and `speed`. The format for each setting is:
```
obs_type = weewx_unit_name
```
Where `obs_type` is one of `temperature`, `pressure`, `rain` or `speed` and `weewx_unit_name` is the WeeWX unit name of the units used by that particular `obs_type` (refer to the [_Units_](../reference/units.md) for details of available WeeWX unit names). As WeatherCat supports a different suite of possible units only a subset of the available WeeWX unit names can be used for some settings.
There is no default.

## Dealing with import failures {#import_failures}
Sometimes bad things happen during an import.
If errors were encountered, or if you suspect that the WeeWX database has been contaminated with incorrect data, here are some things you can try to fix things up.
* Manually delete the contaminated data. Use SQL commands to manipulate the data in the WeeWX archive database. The simplicity of this process will depend on your ability to use SQL, the amount of data imported, and whether the imported data was dispersed amongst existing. Once contaminated data have been removed the daily summary tables will need to be rebuilt using the `weectl database rebuild-daily` utility.
* Delete the database and start over. For SQLite, simply delete the database file. For MySQL, drop the database. Then try the import again.
!!! Warning
Deleting the database file or dropping the database will result in all data in the database being lost.
* If the above steps are not appropriate the database should be restored from backup. You did make a backup before starting the import?

!!! Warning
Running WeeWX during a `wee_import` session can lead to abnormal termination of the import. If WeeWX must remain running (e.g., so that live data is not lost) run the `wee_import` session on another machine or to a second database and merge the in-use and second database once the import is complete.
`wee_import` can import historical observation data for a Weather Underground PWS via the Weather Underground API. The Weather Underground API provides historical weather station observations received by Weather Underground for the PWS concerned on a day by day basis. As such, the data is analogous to the WeeWX archive table. When `wee_import` imports data from the Weather Underground API each day is considered a 'period'. `wee_import` processes one period at a time in chronological order (oldest to newest) and provides import summary data on a per period basis.
## Mapping data to archive fields
A Weather Underground import will populate WeeWX archive fields as follows:
* Provided data exists for each field returned by the Weather Underground API, the following WeeWX archive fields will be directly populated by imported data:
* `dateTime`
* `barometer`
* `dewpoint`
* `heatindex`
* `outHumidity`
* `outTemp`
* `radiation`
* `rain`
* `rainRate`
* `UV`
* `windchill`
* `windDir`
* `windGust`
* `windSpeed`
!!! Note
If an appropriate field is not returned by the Weather Underground API the corresponding WeeWX archive field will contain no data. If the API returns an appropriate field but with no data, the corresponding WeeWX archive field will be set to `None/null`. For example, if the API response has no solar radiation field the WeeWX `radiation` archive field will have no data stored. However, if the API response has a solar radiation field but contains no data, the WeeWX `radiation` archive field will be `None/null`.
* The following WeeWX archive fields will be populated from other settings or configuration options:
* `interval`
* `usUnits`
* The following WeeWX archive fields will be populated with values derived from the imported data provided `calc_missing = True` is included in the `[WU]` section of the import configuration file and the field exists in the in-use WeeWX archive table schema.
* `altimeter`
* `ET`
* `pressure`
!!! Note
If `calc_missing = False` is included in the `[WU]` section of the import configuration file being used then all of the above fields will be set to `None/null`. The `calc_missing` option default is `True`.
## Step-by-step instructions
To import observations from a Weather Underground PWS history:
1. Obtain the weather station ID of the Weather Underground PWS from which data is to be imported. The station ID will be a sequence of numbers and upper case letters that is usually 11 or 12 characters in length. For the purposes of the following examples a weather station ID of `ISTATION123` will be used.
1. Obtain the API key to be used to access the Weather Underground API. This will be a seemingly random alphanumeric sequence of 32 characters. API keys are available to Weather Underground PWS contributors by logging on to their Weather Underground account and accessing Member Settings.
1. Make a backup of the WeeWX database in case the import should go awry.
1. Create an import configuration file. In this case we will make a copy of the example Weather Underground import configuration file and save it as `wu.conf` in the `/var/tmp` directory:
```
$ cp /home/weewx/util/import/wu-example.conf /var/tmp/wu.conf
```
1. Confirm that the [`source`](../wee_import-config#import_config_source) option is set to `WU`:
```
source = WU
```
1. Confirm that the following options in the `[WU]` section are correctly set:
* [station_id](../wee_import-config#wu_station_id). The 11 or 12 character weather station ID of the Weather Underground PWS that will be the source of the imported data.
* [api_key](../wee_import-config#wu_api_key). The 32 character API key to be used to access the Weather Underground API.
* [interval](../wee_import-config#wu_interval). Determines how the WeeWX interval field is derived.
* [qc](../wee_import-config#wu_qc). Determines whether quality control checks are performed on the imported data.
!!! Note
As Weather Underground imports at times contain nonsense values, particularly for fields for which no data were uploaded to Weather Underground by the PWS, the use of quality control checks on imported data can prevent these nonsense values from being imported and contaminating the WeeWX database.
* [calc_missing](../wee_import-config#wu_calc_missing). Determines whether missing derived observations will be calculated from the imported data.
* [ignore_invalid_data](../wee_import-config#wu_ignore_invalid_data). Determines whether invalid data in a source field is ignored or the import aborted.
* [tranche](../wee_import-config#wu_tranche). The number of records written to the WeeWX database in each transaction.
* [wind_direction](../wee_import-config#wu_wind_direction). Determines how imported wind direction fields are interpreted.
1. When first importing data it is prudent to do a dry run import before any data is actually imported. A dry run import will perform all steps of the import without actually writing imported data to the WeeWX database. In addition, consideration should be given to any additional options to be used such as `--date`, `--from` or `--to`.
To perform a dry run enter the following command:
```
wee_import --import-config=/var/tmp/wu.conf --from=2016-01-20T22:30 --to=2016-01-23T06:00 --dry-run
```
In this case the `--from` and `--to` options have been used to import Weather Underground records from 10:30pm on 20 January 2016 to 6:00am on 23 January 2016 inclusive.
!!! Note
If the `--date` option is omitted, or a date (not date-time) range is specified using the `--from` and `--to` options during a Weather Underground import, then one or more full days of history data will be imported. This includes records timestamped from `00:00` (inclusive) at the start of the day up to but NOT including the `00:00` record at the end of the last day. As the timestamped record refers to observations of the previous interval, such an import actually includes one record with observations from the previous day (the `00:00` record at the start of the day). Whilst this will not present a problem for `wee_import` as any records being imported with a timestamp that already exists in the WeeWX database are ignored, you may wish to use the `--from` and `--to` options with a suitable date-time range to precisely control which records are imported.
!!! Note
`wee_import` obtains Weather Underground daily history data one day at a time via a HTTP request and as such the import of large time spans of data may take some time. Such imports may be best handled as a series of imports of smaller time spans.
This will result in a short preamble with details on the data source, the destination of the imported data and some other details on how the data will be processed. The import will then be performed but no data will be written to the WeeWX database.
The output should be similar to:
```
Using WeeWX configuration file /home/weewx/weewx.conf
Starting wee_import...
Observation history for Weather Underground station 'ISTATION123' will be imported.
Using database binding 'wx_binding', which is bound to database 'weewx.sdb'
Destination table 'archive' unit system is '0x01' (US).
Missing derived observations will be calculated.
Observations timestamped after 2016-01-20 22:30:00 AEST (1453293000) and up to and
including 2016-01-23 06:00:00 AEST (1453492800) will be imported.
This is a dry run, imported data will not be saved to archive.
Starting dry run import ...
Records covering multiple periods have been identified for import.
Period 1 ...
Unique records processed: 18; Last timestamp: 2016-01-20 23:55:00 AEST (1453298100)

Period 4 ...

Finished dry run import
657 records were processed and 657 unique records would have been imported.
```
!!! Note
Any periods for which no data could be obtained will be skipped. The lack of data may be due to an incorrect station ID, an incorrect date or Weather Underground API problems. A short explanatory note to this effect will be displayed against the period concerned and an entry included in the log.
1. Once the dry run results are satisfactory the source data can be imported using the following command:
```
wee_import --import-config=/var/tmp/wu.conf --from=2016-01-20T22:30 --to=2016-01-23T06:00
```
This will result in a short preamble similar to that of a dry run. At the end of the preamble there will be a prompt:
```
Using WeeWX configuration file /home/weewx/weewx.conf
Starting wee_import...
Observation history for Weather Underground station 'ISTATION123' will be imported.

Starting import ...

Are you sure you want to proceed (y/n)?
```
!!! Note
`wee_import` obtains Weather Underground data one day at a time via a HTTP request and as such the import of large time spans of data may take some time. Such imports may be best handled as a series of imports of smaller time spans.
1. If the import parameters are acceptable enter `y` to proceed with the import or `n` to abort the import. If the import is confirmed, the source data will be imported, processed and saved in the WeeWX database. Information on the progress of the import will be displayed similar to the following:
```
Unique records processed: 18; Last timestamp: 2016-01-20 23:55:00 AEST (1453298100)
Period 2 ...
Unique records processed: 284; Last timestamp: 2016-01-21 23:55:00 AEST (1453384500)
Period 3 ...
Unique records processed: 284; Last timestamp: 2016-01-22 23:55:00 AEST (1453470900)
```
!!! Note
Any periods for which no data could be obtained will be skipped. The lack of data may be due to an incorrect station ID, an incorrect date or Weather Underground API problems. A short explanatory note to this effect will be displayed against the period concerned and an entry included in the log.
The line commencing with `Unique records processed` should update as records are imported with progress information on number of records processed, number of unique records imported and the date time of the latest record processed. If the import spans multiple days then a new `Period` line is created for each day.
Once the initial import is complete `wee_import` will, if requested, calculate any missing derived observations and rebuild the daily summaries. A brief summary should be displayed similar to the following:
```
Calculating missing derived observations ...
Processing record: 204; Last record: 2016-01-22 23:55:00 AEST (1453470900)
Recalculating daily summaries...
Finished recalculating daily summaries
Finished calculating missing derived observations
```
When the import is complete a brief summary is displayed similar to the following:
```
Finished import
657 records were processed and 657 unique records imported in 78.97 seconds.
Those records with a timestamp already in the archive will not have been
imported. Confirm successful import in the WeeWX log file.
```
!!! Note
The new (2019) Weather Underground API appears to have an issue when obtaining historical data for the current day. The first time the API is queried the API returns all historical data up to and including the most recent record. However, subsequent later API queries during the same day return the same set of records rather than all records up to and including the time of the latest API query. Users importing Weather Underground data that includes data from the current day are advised to carefully check the WeeWX log to ensure that all expected records were imported. If some records are missing from the current day try running an import for the current day again using the `--date` option setting. If this fails then wait until the following day and perform another import for the day concerned again using the `--date` option setting. In all cases confirm what data has been imported by referring to the WeeWX log.
1. Whilst `wee_import` will advise of the number of records processed and the number of unique records found, `wee_import` does know how many, if any, of the imported records were successfully saved to the database. You should look carefully through the WeeWX log file covering the `wee_import` session and take note of any records that were not imported. The most common reason for imported records not being saved to the database is because a record with that timestamp already exists in the database, in such cases something similar to the following will be found in the log:
```
Aug 22 14:38:28 stretch12 weewx[863]: manager: unable to add record 2018-09-04 04:20:00 AEST (1535998800) to database 'weewx.sdb': UNIQUE constraint failed: archive.dateTime
```
In such cases you should take note of the timestamp of the record(s) concerned and make a decision about whether to delete the pre-existing record and re-import the record or retain the pre-existing record.

# weectl import
Some WeeWX users will have historical data from another source (e.g., other
weather station software or a manually compiled file) which they wish to
import into WeeWX. Such data can, depending upon the source, be imported
using the `weectl import` utility.
The `weectl import` utility supports importing observational data from the
following sources:
* a single [Comma Separated Values (CSV)](weectl-import-csv.md) format file
* the historical observations of a [Weather Underground](weectl-import-wu.md)
personal weather station
* one or more [Cumulus](weectl-import-cumulus.md) monthly log files
* one or more [Weather Display](weectl-import-wd.md) monthly log files
* one or more [WeatherCat](weectl-import-weathercat.md) monthly .cat files

* The file must have a header row consisting of a comma separated list of field names. The field names can be any valid string as long as each field name is unique within the list. There is no requirement for the field names to be in any particular order as long as the same order is used for the observations on each row in the file. These field names will be mapped to WeeWX field names in the `[CSV]` section of the import configuration file.
* The file must have a header row consisting of a comma separated list of
field names. The field names can be any valid string as long as each
field name is unique within the list. There is no requirement for the
field names to be in any particular order as long as the same order is
used for the observations on each row in the file. These field names
will be mapped to WeeWX field names in the `[CSV]` section of the import
configuration file.
* Observation data for a given date-time must be listed on a single line with individual fields separated by a comma. The fields must be in the same order as the field names in the header row.
* Observation data for a given date-time must be listed on a single line
with individual fields separated by a comma. The fields must be in the

## Mapping data to archive fields
The WeeWX archive fields populated during a CSV import depend on the CSV-to-WeeWX field mappings specified in `[[FieldMap]]` stanza in the import configuration file. If a valid field mapping exists, the WeeWX field exists in the WeeWX archive table schema and provided the mapped CSV field contains valid data, the corresponding WeeWX field will be populated. Note that the CSV import is the only import supported by `wee_import` that allows any WeeWX archive field to be populated.

## Dealing with import failures {#import_failures}
Sometimes bad things happen during an import.
If errors were encountered, or if you suspect that the WeeWX database has
been contaminated with incorrect data, here are some things you can try to
fix things up.
* Manually delete the contaminated data. Use SQL commands to manipulate
the data in the WeeWX archive database. The simplicity of this process
will depend on your ability to use SQL, the amount of data imported, and
whether the imported data was dispersed amongst existing. Once
contaminated data have been removed the daily summary tables will need
to be rebuilt using the `weectl database rebuild-daily` utility.
* Delete the database and start over. For SQLite, simply delete the
database file. For MySQL, drop the database. Then try the import again.
!!! Warning
Deleting the database file or dropping the database will result in
all data in the database being lost.
* If the above steps are not appropriate the database should be restored
from backup. You did make a backup before starting the import?

Whilst WeatherCat monthly .cat files use a fixed set of fields the inclusion of fields other than `t` (timestamp) and `V` (validation) is optional. For this reason the field map used for WeatherCat imports includes fields that may not exist in some WeatherCat monthly .cat files resulting in warnings by `wee_import` that there may be missing data in the import source.

!!! Warning
Running WeeWX during a `wee_import` session can lead to abnormal
termination of the import. If WeeWX must remain running (e.g., so that
live data is not lost) run the `wee_import` session on another machine or
to a second database and merge the in-use and second database once the
import is complete.
`wee_import` can import historical observation data for a Weather
Underground PWS via the Weather Underground API. The Weather Underground
API provides historical weather station observations received by Weather
Underground for the PWS concerned on a day by day basis. As such, the data
is analogous to the WeeWX archive table. When `wee_import` imports data
from the Weather Underground API each day is considered a 'period'.
`wee_import` processes one period at a time in chronological order (oldest
to newest) and provides import summary data on a per period basis.
## Mapping data to archive fields
A Weather Underground import will populate WeeWX archive fields as follows:
* Provided data exists for each field returned by the Weather Underground
API, the following WeeWX archive fields will be directly populated by
imported data:
* `dateTime`
* `barometer`
* `dewpoint`
* `heatindex`
* `outHumidity`
* `outTemp`
* `radiation`
* `rain`
* `rainRate`
* `UV`
* `windchill`
* `windDir`
* `windGust`
* `windSpeed`
!!! Note
If an appropriate field is not returned by the Weather Underground
API the corresponding WeeWX archive field will contain no data. If
the API returns an appropriate field but with no data, the
corresponding WeeWX archive field will be set to `None/null`. For
example, if the API response has no solar radiation field the
WeeWX `radiation` archive field will have no data stored. However,
if the API response has a solar radiation field but contains no
data, the WeeWX `radiation` archive field will be `None/null`.
* The following WeeWX archive fields will be populated from other settings
or configuration options:
* `interval`
* `usUnits`
* The following WeeWX archive fields will be populated with values derived
from the imported data provided `calc_missing = True` is included in the
`[WU]` section of the import configuration file and the field exists in
the in-use WeeWX archive table schema.
* `altimeter`
* `ET`
* `pressure`
!!! Note
If `calc_missing = False` is included in the `[WU]` section of the
import configuration file being used then all of the above fields will be
set to `None/null`. The `calc_missing` option default is `True`.
## Step-by-step instructions
To import observations from a Weather Underground PWS history:
1. Obtain the weather station ID of the Weather Underground PWS from which
data is to be imported. The station ID will be a sequence of numbers
and upper case letters that is usually 11 or 12 characters in length.
For the purposes of the following examples a weather station ID of
`ISTATION123` will be used.
1. Obtain the API key to be used to access the Weather Underground API.
This will be a seemingly random alphanumeric sequence of 32 characters.
API keys are available to Weather Underground PWS contributors by
logging on to their Weather Underground account and accessing Member
Settings.
1. Make a backup of the WeeWX database in case the import should go awry.
1. Create an import configuration file. In this case we will make a copy
of the example Weather Underground import configuration file and save
it as `wu.conf` in the `/var/tmp` directory:
```
$ cp /home/weewx/util/import/wu-example.conf /var/tmp/wu.conf
```
1. Confirm that the [`source`](../wee_import-config#import_config_source) option is set to `WU`:
```
source = WU
```
1. Confirm that the following options in the `[WU]` section are correctly set:
* [station_id](../wee_import-config#wu_station_id). The 11 or 12
character weather station ID of the Weather Underground PWS that
will be the source of the imported data.
* [api_key](../wee_import-config#wu_api_key). The 32 character API key
to be used to access the Weather Underground API.
* [interval](../wee_import-config#wu_interval). Determines how the
WeeWX interval field is derived.
* [qc](../wee_import-config#wu_qc). Determines whether quality control
checks are performed on the imported data.
!!! Note
As Weather Underground imports at times contain nonsense
values, particularly for fields for which no data were
uploaded to Weather Underground by the PWS, the use of quality
control checks on imported data can prevent these nonsense
values from being imported and contaminating the WeeWX database.
* [calc_missing](../wee_import-config#wu_calc_missing). Determines
whether missing derived observations will be calculated from the
imported data.
* [ignore_invalid_data](../wee_import-config#wu_ignore_invalid_data).
Determines whether invalid data in a source field is ignored or the
import aborted
* [tranche](../wee_import-config#wu_tranche). The number of records
written to the WeeWX database in each transaction.
* [wind_direction](../wee_import-config#wu_wind_direction). Determines
how imported wind direction fields are interpreted.
1. When first importing data it is prudent to do a dry run import before
any data is actually imported. A dry run import will perform all steps
of the import without actually writing imported data to the WeeWX
database. In addition, consideration should be given to any additional
options to be used such as `--date`, `--from` or `--to`.
To perform a dry run enter the following command:
```
wee_import --import-config=/var/tmp/wu.conf --from=2016-01-20T22:30
--to=2016-01-23T06:00 --dry-run
```
In this case the `--from` and `--to` options have been used to import
Weather Underground records from 10:30pm on 20 January 2016 to 6:00am
on 23 January 2016 inclusive.
!!! Note
If the `--date` option is omitted, or a date (not date-time) range
is specified using the `--from` and `--to` options during a Weather
Underground import, then one or more full days of history data
will be imported. This includes records timestamped from `00:00`
(inclusive) at the start of the day up to but NOT including the
`00:00` record at the end of the last day. As the timestamped
record refers to observations of the previous interval, such an
import actually includes one record with observations from the
previous day (the `00:00` record at the start of the day). Whilst
this will not present a problem for `wee_import` as any records
being imported with a timestamp that already exists in the WeeWX
database are ignored, you may wish to use the `--from` and `--to`
options with a suitable date-time range to precisely control
which records are imported.
!!! Note
`wee_import` obtains Weather Underground daily history data one
day at a time via a HTTP request and as such the import of large time
spans of data may take some time. Such imports may be best handled
as a series of imports of smaller time spans.
This will result in a short preamble with details on the data source,
the destination of the imported data and some other details on how the
data will be processed. The import will then be performed but no data
will be written to the WeeWX database.
The output should be similar to:

Those records with a timestamp already in the archive will not have been
imported. Confirm successful import in the WeeWX log file.
```
!!! Note
The new (2019) Weather Underground API appears to have an issue
when obtaining historical data for the current day. The first time
the API is queried the API returns all historical data up to and
including the most recent record. However, subsequent later API
queries during the same day return the same set of records rather
than all records up to and including the time of the latest API
query. Users importing Weather Underground data that includes data
from the current day are advised to carefully check the WeeWX log
to ensure that all expected records were imported. If some records
are missing from the current day try running an import for the
current day again using the `--date` option setting. If this fails
then wait until the following day and perform another import for
the day concerned again using the `--date` option setting. In all
cases confirm what data has been imported by referring to the
WeeWX log.
1. Whilst `wee_import` will advise of the number of records processed and
the number of unique records found, `wee_import` does know how many, if
any, of the imported records were successfully saved to the database.
You should look carefully through the WeeWX log file covering the
`wee_import` session and take note of any records that were not
imported. The most common reason for imported records not being saved
to the database is because a record with that timestamp already exists
in the database, in such cases something similar to the following will
be found in the log:
```
Aug 22 14:38:28 stretch12 weewx[863]: manager: unable to add record
2018-09-04 04:20:00 AEST (1535998800) to database 'weewx.sdb': UNIQUE
constraint failed: archive.dateTime
```
In such cases you should take note of the timestamp of the record(s)
concerned and make a decision about whether to delete the pre-existing
record and re-import the record or retain the pre-existing record.
