MMM-MQTT module multiple Sensors 433Mhz



  • I got this module running acepting MQTT/JSON from another Pi running rtl_433 with RTL_SDR receiver.

    The problem ist that the topic is always “/home/rtl_433”, and the jsonpointer grabs “/temperature_C” or “/temperature” from all sending 433MHz Sensors.

    They differ only in modelname or rollingcode or channel .
    How do i separate them for Display in that module?

    I guess IF statements in config.js are not possible? I am a very beginner at JAVA.

    Thanks for any help



  • Ok i think now that i need to filter the MQTT stream with node-red and generate separate topics for MM. Can i run MM and node_red together on Pi 3B+ . Has anyone done this already?
