    @NeverDie

    I have started to test node-red (Which dont work yet...) so I have created a dummy sketch for parse the data to domoticz.

    // Enable debug prints
    #define MY_DEBUG
    #define MY_GATEWAY_SERIAL
    
    // Enable passive mode
    #define MY_PASSIVE_NODE
    #define MY_REPEATER_FEATURE
    
    // Passive mode requires static node ID
    #define MY_NODE_ID 0
    
    // Enable and select radio type attached
    // #define MY_RADIO_NRF24
    //#define MY_RF24_PA_LEVEL RF24_PA_HIGH
    
    //#define MY_RADIO_NRF5_ESB
    //#define MY_RADIO_RFM69
    //#define MY_RADIO_RFM95
    
    #include <MySensors.h>
    
    #define CHILD_ID_HUM 0
    #define CHILD_ID_TEMP 1
    #define CHILD_ID_BINARY 2
    
    // Initialize general message
    MyMessage msgTemp(CHILD_ID_TEMP, V_TEMP);
    MyMessage msgHum(CHILD_ID_HUM, V_HUM);
    MyMessage msgBinary(CHILD_ID_BINARY, V_STATUS);
    int counter = 0;
    float temperature = 0;
    float humidity = 0;
    int binary = 0;
    void setup()
    {
    }
    
    void presentation()
    {
      // Send the sketch version information to the gateway and controller
      sendSketchInfo("Passive node", "1.0");
    
      // Register all sensors to gw (they will be created as child devices)
      present(CHILD_ID_TEMP, S_TEMP);
      present(CHILD_ID_HUM, S_HUM);
      present(CHILD_ID_BINARY, S_BINARY);
    }
    
    void loop()
    {
      // generate some random data
      counter ++;
      if (counter == 20 ){
        temperature = 0;
        humidity = 0;
        counter = 0;
      }
      else
      {
        temperature = 25.0 + random(0,30)/10.0;
        humidity = 55.0 + random(-20,20);
      }
    /*
      if (binary == 0){
        send(msgBinary.set(binary,2));
        binary = 1;
      }else {
        send(msgBinary.set(binary,2));
        binary = 0;
    
      }
    */
      send(msgTemp.set(temperature,2));
      send(msgHum.set(humidity,2));
      wait(1000);
    }

    @smilvert I guess it's destiny then: Node Red + MQTT

      Well I wanted to filter noise values and I also want to use influx/grafana as a complement to domoticz

        @smilvert So, do you have the gateway connected directly to Node Red, which then feeds Domoticz and also feeds influx/grafana? I think I want to do the same, if that's how to do it.

            @smilvert I think @Toyman said he has it figured out. Maybe he can tell us how he did it?

              Just cut domoticz out of the picture as node-red/influx/grafana works perfect with any gateway serial/ethernet/mqtt.
              I prefer the serial gateway in my own experience is the most stable and no reliance on wifi routers and things.
              Domoticz has nowhere near the same flexibility when graphing etc.

                @rmtucker Ahhhhhh, that's right, it was rmtucker, not toyman, who had done it: https://forum.mysensors.org/topic/6961/nrf5-bluetooth-action/1078

                  @NeverDie @mfalkvidd Passive nodes communicate without message ACKs - ID requests may never make their way to the controller, hence the requirement of a static node ID.

                    @tekka In that case couldn't it just keep retrying until it received its ID?

                      @NeverDie No, that's not the idea of a passive node. However, with

                      void transportTogglePassiveMode(const bool OnOff)
                      

                      you can enable the passive transport mode, see here for additional information (>=2.2.0)

                        @smilvert Got it working: https://www.openhardware.io/view/510/Multi-Sensor-TempHumidityPIR-LeakMagnetLightAccel#tabs-source

                        I cited you in the credits at the beginning of the sketch.
