Keep information about the previous value sent. If it's been 5
seconds, or new value is different (ignoring keys like snr and
frequency), then send it. Otherwise, just don't. This causes bursts
of e.g. 4 transmissions to result in one MQTT message, on the theory
that the 4 transmissions are not actually 4 messags, but a strategy to
transmit one message more reliably.
Define a new configuration option to enable duplicate filtering, and
default it to True.
Steal logging config from mqtt_filter.py, and add a configuration
option DEBUG that if True results in debug logging instead of info.
This commit adds the ability to read config values from
rtl_433_mqtt_relay.yaml (overriding defaults). This read is skipped
if the yaml module can't be loaded or the config file can't be read,
so those without PyYAML or a config file see no change.
Those with a config file can set parameters for address/port to listen
for json-in-sylog, MQTT credentials, whether to post individual
values, a json dictionary, or both.
While rudimentary, this is a huge functional improvement, allowing
those using TLS and broker passwords (as arguably all should be) to
use the script without modifying it.
Previously, this example program appended /channel if present, and if
not present and id was present, appended /id. Typically channel is
from an A/B/C switch on the device or fixed for kind of device, and id
is from a 16 bit or larger space, sometimes static, and sometimes
random on powerup. Using only channel is bad if 1) one has more than
one device, or more than 3 if A/B/C or 2) one's neighbor gets such a
device. Because it is essentially impossible to rule out point 2, id
should always be used.
* floating point literals must use the f suffix when working with float variables
* when a double is expected, do not force to use float computation by using a float literal
Add variables to control publishing individual topics and the json
topic. Default both to on, so that there is no behavior change.
This eases use now, as one's local diff is cleaner. It is also on the
path to reading these variables from a config file.
* Add support for ThermoPro TP829b and Improve rtl_433_mqtt_hass.py
* Improve DATA_COND with int values instead of float
* Fix Sensor ID, Add Display Unit and Flags and reduce preamble
Expand description of the directory, making it clearer that some
programs have production use.
Declare that python scripts are python3. It's clear that nobody is
trying to use them with python 2.7, and if they did, we would tell
them not to.
List the scripts with a one-line description, sorting them into
production (none yet), generally usable, and true examples. Leave
some uncategorized.
