Integration
Integration of rtl_433 output into various home automation gateways.
::: tip If you are a user of one these systems, please help to confirm and extend the information here. :::
openHAB
openHAB - open source automation software for your home
See the wiki page https://github.com/merbanan/rtl_433/wiki/How-to-integrate-rtl_433-sensors-into-openHAB-via-MQTT
Some help comes from https://community.openhab.org/t/rtl-433-to-mqtt/80652/3
Run
rtl_433 -F "mqtt://192.168.178.42:1883,retain=0,devices=sensors/rtl_433/P[protocol]/C[channel]"
This produces some topics in the broker like this:
sensors/rtl_433/P25/C1/id 147
sensors/rtl_433/P25/C1/temperature_C 33.200001
sensors/rtl_433/P25/C1/rain_mm 107.699997
sensors/rtl_433/P25/C1/battery_ok 1
sensors/rtl_433/P25/C1/mic CRC
You can easily set up some MQTT things then:
Bridge mqtt:broker:My-MQTT "MQTT Broker" @ "RTL433" [
host="192.168.x.x",
secure=false,
port=1883,
qos=0,
retain=false,
clientid="Oh2Mqtt2Thing",
keep_alive_time=30000,
reconnect_time=60000
]
{
Thing topic RTL_433 "433MHz Empfänger" @ "RTL433" {
Channels:
Type number : temp "Temperatur" [ stateTopic="sensors/rtl_433/P25/C1/temperature_C" ]
Type number : hum "Luftfeuchtigkeit" [ stateTopic="sensors/rtl_433/P25/C1/humidity" ]
Type switch : batt "Battery schwach" [ stateTopic="sensors/rtl_433/P25/C1/battery", transformationPattern="MAP:battery.map"]
}
}
Home Assistant
Home Assistant - Open source home automation
Home Assistant has good MQTT support and can read rtl_433 event topics.
::: warning Example needed :::
See also rtl_433_mqtt_hass.py MQTT Home Assistant auto discovery.
Domoticz
Domoticz - Home Automation System
Domoticz has built-in support for reading from rtl_433 using pipes.
There is also a newer plugin using MQTT: enesbcs/pyrtl433.
::: warning Testing and example needed :::
NodeRED
NodeRED - Flow-based programming for the Internet of Things
Node RED has built-in support for reading from MQTT and thus rtl_433 events.

Databases
You likely need to filter and transform rtl_433's output before sending it to a database. It's recommended you read the JSON data and process it to your specific requirements.
Some example pipes/relays for rtl_433 JSON data. Should work with Python 2 and also Python 3.
The pipe
examples read JSON output from rtl_433
using a pipe, i.e.
rtl_433 -F json ... | rtl_433_statsd_pipe.py
The relay
examples consumes the (UDP) Syslog output from rtl_433 (or a legacy plain JSON datagram).
Basically run rtl_433
with -F syslog:127.0.0.1:1433
and the relay script as an unrelated process, i.e.
rtl_433_mqtt_relay.py &
rtl_433 -F syslog:127.0.0.1:1433
