My AddOn setup:
- rtl_433 (next) AddOn for broadcast the sensor information to my external MQTT broker
/config/rtl433/rtl433.conf
output mqtt://${host}:${port},user=${username},pass=${password},retain=${retain},devices=rtl_433/9b13b3f4-rtl433/devices[/type][/model][/subtype][/channel][/id],events=rtl_433/9b13b3f4-rtl433/events,states=rtl_433/9b13b3f4-rtl433/states
Due to that one line the AddOn was directly publishing the following structure
MQTT: Publishing availability to MQTT topic “rtl_433/9b13b3f4-rtl433-next/availability”.
MQTT: Publishing device info to MQTT topic “rtl_433/9b13b3f4-rtl433/devices[/type][/model][/subtype][/channel][/id]”.
MQTT: Publishing events info to MQTT topic “rtl_433/9b13b3f4-rtl433/events”.
MQTT: Publishing states info to MQTT topic “rtl_433/9b13b3f4-rtl433/states”.
- rtl_433 AutoDiscovery (next) for auto creating the sensors (now with real data from the sensors)
Used the default settings, only force_update was activated (recommended for initial setup/start). I’ve added only the MQTT-Broker settings IP/Port & Credentials and after start/restart the new sensors were announced in HomeAssistant with valid/current data.
=====
The biggest issue I’d was that the sensor data are always showing up with the value “unknown”. The correct output command did the trick for me as not only events was send to the MQTT brocker with that.
