2nd sensor in sketch not showing up in HA



  • I am trying to modify my working moisture sensor sketch to present 2 child Ids instead of one. Arduino serial monitor shows the data from both sensors and HA sees it but the 2nd sensor does not show up in unused entities. I am confident I am erring in my sketch somehow but not sure where.

    /*
      AnalogReadSerial
    
      Reads an analog input on pin 0, prints the result to the Serial Monitor.
      Graphical representation is available using Serial Plotter (Tools > Serial Plotter menu).
      Attach the center pin of a potentiometer to pin A0, and the outside pins to +5V and ground.
    
      This example code is in the public domain.

    MyMessage msg(CHILD_ID_A0, V_LEVEL);
    MyMessage msg2(CHILD_ID_A1, V_LEVEL);
    // the setup routine runs once when you press reset:
    void setup() {
      // initialize serial communication at 9600 bits per second:
      Serial.begin(9600);
    }
    void presentation()
    {
      sendSketchInfo("Analog Soil Moisture Sensor", "1c.0");
      present(CHILD_ID_A0, S_MOISTURE);
      present(CHILD_ID_A1, S_MOISTURE);
    }
    // the loop routine runs over and over again forever:
    void loop() {
      // read the input on analog pin 0:
      int sensorValue = analogRead(A0);
      int sensorValueA1 = analogRead(A1);
      // print out the value you read:
      Serial.println(sensorValue);
      Serial.println(sensorValueA1);
      send(msg.set(sensorValue));
      send(msg.set(sensorValueA1));
      delay(10000);        // delay in between reads for stability
    }
    

    HA logs:

    2020-03-16 15:56:04 WARNING (MainThread) [mysensors.sensor] child_id 0 already exists in children of node 105, cannot add child
    2020-03-16 15:56:04 WARNING (MainThread) [mysensors.sensor] child_id 1 already exists in children of node 105, cannot add child
    


  • @mrhutchinsonmn I think the error indicates the child already exist, so you could try to change the node id, or modify the persistence file manually:
    https://forum.mysensors.org/topic/10901/manual-adjust-the-persistence-file-instead-of-adjust-the-node-s/3



  • @mrhutchinsonmn said in 2nd sensor in sketch not showing up in HA:

    MyMessage msg(CHILD_ID_A0, V_LEVEL);
    MyMessage msg2(CHILD_ID_A1, V_LEVEL);
    [...]
    void loop() {
      [...]
      send(msg.set(sensorValue));
      send(msg.set(sensorValueA1));
       [...]
    }
    

    You are sending both sensor values with the same message, so they both get reported to child ID 0 and child ID 1 will never show up.

    Change the second send function from
    send(msg.set(sensorValueA1));
    to
    send(msg2.set(sensorValueA1));



  • @BearWithBeard You beat me to it by a minute! 😉



  • @BearWithBeard said in 2nd sensor in sketch not showing up in HA:

    send(msg2.set(sensorValueA1));

    Yes, that was it!! Thank you!!
