AP_DESCRIPTION="""
Publish Home Assistant MQTT auto discovery topics for rtl_433 devices.
rtl_433_mqtt_hass.py connects to MQTT and subscribes to the rtl_433
event stream that is published to MQTT by rtl_433. The script publishes
additional MQTT topics that can be used by Home Assistant to automatically
discover and minimally configure new devices.
The configuration topics published by this script tell Home Assistant
what MQTT topics to subscribe to in order to receive the data published
as device topics by MQTT.
"""
AP_EPILOG="""
It is strongly recommended to run rtl_433 with "-C si".
This script requires rtl_433 to publish both event messages and device
messages. If you've changed the device topic in rtl_433, use the same device
topic with the "-T" parameter.
MQTT Username and Password can be set via the cmdline or passed in the
environment: MQTT_USERNAME and MQTT_PASSWORD.
Prerequisites:
1. rtl_433 running separately publishing events and devices messages to MQTT.
2. Python installation
* Python 3.x preferred.
* Needs Paho-MQTT https://pypi.python.org/pypi/paho-mqtt
Debian/raspbian: apt install python3-paho-mqtt
Or
pip install paho-mqtt
* Optional for running as a daemon see PEP 3143 - Standard daemon process library
(use Python 3.x or pip install python-daemon)
Running:
This script can run continually as a daemon, where it will publish
a configuration topic for the device events sent to MQTT by rtl_433
every 10 minutes.
Alternatively if the rtl_433 devices in your environment change infrequently
this script can use the MQTT retain flag to make the configuration topics
persistent. The script will only need to be run when things change or if
the MQTT server loses its retained messages.
Getting rtl_433 devices back after Home Assistant restarts will happen
more quickly if MQTT retain is enabled. Note however that definitions
for any transitient devices/false positives will retained indefinitely.
If your sensor values change infrequently and you prefer to write the most
recent value even if not changed set -f to append "force_update = true" to
all configs. This is useful if you're graphing the sensor data or want to
alert on missing data.
If you have changed the topic structure from the default topics in the rtl433
configuration use the -T parameter to set the same topic structure here.
Suggestions:
Running this script will cause a number of Home Assistant entities (sensors
and binary sensors) to be created. These entities can linger for a while unless
the topic is republished with an empty config string. To avoid having to
do a lot of clean up When running this initially or debugging, set this
script to publish to a topic other than the one Home Assistant users (homeassistant).
MQTT Explorer (http://mqtt-explorer.com/) is a very nice GUI for
working with MQTT. It is free, cross platform, and OSS. The structured
hierarchical view makes it easier to understand what rtl_433 is publishing
and how this script works with Home Assistant.
MQTT Explorer also makes it easy to publish an empty config topic to delete an
entity from Home Assistant.
As of 2020-10, Home Assistant MQTT auto discovery doesn't currently support
supplying "friendly name", and "area" key, so some configuration must be
done in Home Assistant.
There is a single global set of field mappings to Home Assistant meta data.
