Fields Mysensors

  • Hello
    discovering MyController2
    I'm trying to understand how to get the data back
    of Mysensors in the dashboard.

    the question is :
    how to differentiate my sensors in the Widgets?

    in the example of the pdf file
    I have two V_TEMP and two V_HUM

    a test by renaming Name :V_TEMP to V_TEMP1 gave nothing, TEMP1 comes back as TEMP

    in short it is the fog

    how do we use the labels?
    I didn't find any doc on the subject with Mysensors


  • I found it 😉

    in Resource Filters

    Key : sourceid
    Value : 2

    (I update my pdf)

    yeah the doc on the use of
    "Resource Filters" with "Key" "Value"
    values would be nice

    it's really a pity that you can't modify your previous post, too short delay, minimum one month 🙂

  • Hello
    a tutorial / help for the structure
    (the skeleton) of a MySensors sketch.

    to go back automatically to MyController
    the nodes and sensors

    here is an example in image (pdf)
    texte du lien

    and the sketch (Mysensors parts only )

    // ------ Mysensors V2 ------- //
      #define MY_NODE_ID 32   /*Node ID static*/
      #define CHILD_ID_R 3    /*Id  Relay*/
      #define CHILD_ID_B 4    /*Id  Door*/
      MyMessage msg(CHILD_ID_R,V_STATUS);  
      MyMessage msg1(CHILD_ID_B,V_TRIPPED);  
      void setup() { .... }
      void presentation()   {
      sendSketchInfo("DiDo node 32", "2.0");  /* version sketch*/
    //Mysenors save Child and Gw
      present(CHILD_ID_R, S_BINARY);  /*output digital*/
      present(CHILD_ID_B, S_DOOR);    /*input digital*/  
      request(CHILD_ID_R, V_STATUS);    /*request value of the controller*/
      request(CHILD_ID_B, V_STATUS); 
    ... }
     void loop()  { ...
    //  send(msg.set(value==HIGH ? 1 : 0));      /*Relay 
        send(msg1.set(value==HIGH ? 1 : 0));     /*Door 
    void receive(const MyMessage &message)  {
       if (message.type == V_STATUS) 
       state = message.getBool ();
       digitalWrite(RELAY_PIN, state?RELAY_ON:RELAY_OFF);  /*Change relay state*/
       if (message.getType()==V_STATUS) 
       //digitalWrite(message.getSensor() - RELAY_PIN, message.getBool()?RELAY_ON:RELAY_OFF);
    ... }

    a question : I don't understand the use of
    "message.getType" and "message.getBool" ?

    one instruction too many ??

    @JeeLet can you add send(msg.set(value==HIGH ? 1 : 0)); // Relay in your setup(){} function?

  • Hello jkandasa

    I spent the day on the Mysensors website copying/translating some parts of the "serial_api_20" doc
    (I have no more eyes 🙂 )

    yes I will add it soon
    send(msg.set(value==HIGH ? 1 : 0)); // Relay

    you mas understood, I try to write well the code of the sckech
    so that MyCrontroller goes up cleanly the sensors 🙂


  • exit status 1 : 'value' was not declared in this scope

    but why in the setup ?
    you have to put it in Loop () ?

    @JeeLet the value, you have to set.
    V_STATUS is not available in MyController, since it is not reported yet.
    adding in setup sends the data only once. If you would like to retain the old status from MyController in your node, remove the send(msg.set(value==HIGH ? 1 : 0)); from your setup and create V_STATUS manually in MyController

    • add new field in Resources >> Fields >> Add,

  • can be the good solution to put everything back to MyController

    without doing anything 🙂

     bool info;
    Void setup  {......
      //info send to gateway
       send(msgx.set(info)); //pour d'autres  

    to be seen later
