"""Import WeeWX observation data from an external source.
Compatibility:
wee_import can import from:
- a Comma Separated Values (CSV) format file
- the historical records of a Weather Underground Personal
Weather Station
- one or more Cumulus monthly log files
- one or more Weather Display monthly log files
Design
wee_import utilises an import config file and a number of command line
options to control the import. The import config file defines the type of
input to be performed and the import data source as well as more advanced
options such as field maps etc. Details of the supported command line
parameters/options can be viewed by entering wee_import --help at the
command line. Details of the wee_import import config file settings can be
found in the example import config files distributed in the
weewx/util/import directory.
wee_import utilises an abstract base class Source that defines the majority
of the wee_import functionality. The abstract base class and other
supporting structures are in bin/weeimport/weeimport.py. Child classes are
created from the base class for each different import type supported by
wee_import. The child classes set a number of import type specific
properties as well as defining getData() and period_generator() methods that
read the raw data to be imported and generates a sequence of objects to be
imported (eg monthly log files) respectively. This way wee_import can be
extended to support other sources by defining a new child class, its
specific properties as well as getData() and period_generator() methods. The
child class for a given import type are defined in the
bin/weeimport/xxximport.py files.
As with other WeeWX utilities, wee_import advises the user of basic
configuration, action taken and results via the console. However, since
wee_import can make substantial changes to the WeeWX archive, wee_import
also logs to WeeWX log system file. Console and log output can be controlled
via a number of command line options.
Prerequisites
wee_import uses a number of WeeWX API calls and therefore must have a
functional WeeWX installation. wee_import requires WeeWX 4.0.0 or later.
Configuration
A number of parameters can be defined in the import config file as follows:

# Specify the source. Available options are:
# CSV - import obs from a single CSV format file

# Path and name of our CSV source file. Format is:
# file = full path and filename
file = /var/tmp/data.csv
# If there is no mapped interval field how will the interval field be
# determined for the imported records. Available options are:
# derive - Derive the interval field from the timestamp of successive
# records. This setting is best used when the imported records
# are equally spaced in time and there are no missing records.
# conf - Use the interval setting from weewx.conf. This setting is
# best used if the records to be imported have been produced by
# WeeWX using the same archive interval as set in weewx.conf on
# this machine.
# x - Use a fixed interval of x minutes for every record. This
# setting is best used if the records to be imported are
# equally based in time but there are some missing records.
#
# Note: If there is a mapped interval field then this setting will be
# ignored.
# Format is:
# interval = (derive | conf | x)

# Should the [StdQC] max/min limits in weewx.conf be applied to the
# imported data. This may be useful if the source has extreme values that
# are clearly incorrect for some observations. Available options are:

# False - weewx.conf [StdQC] max/min limits are not applied.
# Format is:
# qc = (True | False)

# Should any missing derived observations be calculated from the imported
# data if possible. Available options are:
# True - Any missing derived observations are calculated.
# False - Any missing derived observations are not calculated.
# Format is:
# calc_missing = (True | False)

# Imported records are written to archive in transactions of tranche
# records at a time. Increase for faster throughput, decrease to reduce

# Specify whether a UV sensor was used to produce any UV observations.
# Available options are:
# True - UV sensor was used and UV data will be imported.
# False - UV sensor was not used and any UV data will not be imported.
# UV fields will be set to None/NULL.
# For a CSV import UV_sensor should be set to False if a UV sensor was
# NOT present when the import data was created. Otherwise it may be set to
# True or omitted. Format is:

# Specify whether a solar radiation sensor was used to produce any solar
# radiation observations. Available options are:

# be imported.
# False - Solar radiation sensor was not used and any solar radiation
# data will not be imported. radiation fields will be set to
# None/NULL.
# For a CSV import solar_sensor should be set to False if a solar radiation
# sensor was NOT present when the import data was created. Otherwise it may

# Date-time format of CSV field from which the WeeWX archive record
# dateTime field is to be extracted. wee_import first attempts to interpret

#
# where:
# weewx_archive_field_name - An observation name in the WeeWX database
# schema.
# csv_field_name - The name of a field from the CSV file.
# weewx_unit_name - The name of the units, as defined in WeeWX,
# used by csv_field_name. This value represents
# the units used for this field in the CSV
# file, wee_import will do the necessary
# conversions to the unit system used by the
# WeeWX archive.
# For example,
# outTemp = Temp, degree_C
# would map the CSV field Temp, in degrees C, to the archive field outTemp.
#
# If a field mapping exists for the WeeWX usUnits archive field then the
# units option may be omitted for each mapped field.
#
# WeeWX archive fields that do not exist in the CSV data may be omitted. Any

Adding a New Import Source
To add a new import source:
- Create a new file bin/weeimport/xxximport.py that defines a new class
for the xxx source that is a child of class Source. The new class must
meet the following minimum requirements:
- __init__() must define:
- self.raw_datetime_format: Format of date time data field from
which observation timestamp is to be
derived. String comprising Python
strptime() format codes.
- self.rain: Whether imported rainfall field contains the
rainfall since the last record or a cumulative value.
String 'discrete' or 'cumulative'
- self.wind_dir: The range of values in degrees that will be
accepted as a valid wind direction. Two way
tuple of the format (lower, upper) where lower
is the lower inclusive limit and upper is the
upper inclusive limit.
- Define a period_generator() method that:
- Accepts no parameters and generates (yields) a sequence of
objects (eg file names, dates for a http request etc) that are
passed to the getRawData() method to obtain a sequence of raw
data records.
- Define a getRawdata() method that:
- Accepts a single parameter 'period' that is provided by the
period_generator() method.
- Returns an iterable of raw source data records.
- Creates the source data field-to-WeeWX archive field map and
saves the map to the class object map property (the map may be
created using the Source.parseMap() method). Refer to
getRawData() methods in csvimport.py and wuimport.py.
- Modify bin/weeimport/weeimport.py as follows:
- Add a new entry to the list of supported services defined in
SUPPORTED_SERVICES.
- Create a wee_import import config file for importing from the new
source. The import config file must:
- Add a new source name to the source parameter. The new source name
must be the same (case sensitive) as the entry added to
weeimport.py SUPPORTED_SERVICES.
- Define a stanza for the new import type. The stanza must be the
same (case sensitive) as the entry added to weeimport.py
SUPPORTED_SERVICES.
