Mqtt + sensors



  • I have now trying the setup where I have on raspberry 3 mosquitto as MQTT running and mysensors gateway also setup there. As controller I'm using home assistant.
    I can see that mqtt receives data from gateway.
    But how do I send data from my sensors (atmega328p) over nrf24l01+ to gateway?
    What do I need to add in the skatch?

    gateway:

    mysgw: Starting gateway...
    mysgw: Protocol version - 2.2.0-beta
    mysgw: MCO:BGN:INIT GW,CP=RNNG----,VER=2.2.0-beta
    mysgw: TSF:LRT:OK
    mysgw: TSM:INIT
    mysgw: TSF:WUR:MS=0
    mysgw: TSM:INIT:TSP OK
    mysgw: TSM:INIT:GW MODE
    mysgw: TSM:READY:ID=0,PAR=0,DIS=0
    mysgw: MCO:REG:NOT NEEDED
    mysgw: MCO:BGN:STP
    mysgw: MCO:BGN:INIT OK,TSP=1
    mysgw: Attempting MQTT connection...
    mysgw: connected to 127.0.0.1
    mysgw: MQTT connected
    mysgw: Sending message on topic: mysensors-out/0/255/0/0/18
    

    skatch:

     * The MySensors Arduino library handles the wireless radio link and protocol

     * network topology allowing messages to be routed to nodes.

    @alop what happens when you run the node?
