    You could try editing out all the ifs etc in the getStateFromController and only request the state (surrounded by a few serial prints to see which bits execute). If it works in simplest form then you could build up the logic around it to see what is failing

    void getStateFromController() {
    
      Serial.println(" starting GetStateFromController");
      request( CHILD_ID_RELAY , V_STATUS);
      wait (WAIT_RETURN);
     serial.print("Waiting");
    
    }

      I still miss the point in asking the status of the relay...

        @Ben-Andrewes request return every time "1". This is not the state of relay in Domoticz . The following state from Domoticz is "0", either if in Domoticz relay need to be on or off ....

          @gohan to mantain them in sync after a power failure.

          But you did put me on right way. I could simply put the relay off on Arduino start and send off to Domoticz.

          Every 5 minutes I could send the corrent state ti Domoticz (Imagine a gateway Power failure instead).

          In this mode I delegate all logic to Domoticz, when the relay need to be on or off....

            There is the savestate and readstate functions in mysensors in case you need it

              @gohan I know, but I would to not use the EEprom and I would also learn and understand where is my error / why cannot get the state... :)

                I was just trying to point out that it is a design flaw as the nodes should be as much as indipendent as possible from controller but if you want to play around, have fun

                  Ok,
                  I don't know if it is necessary to open a new post.

                  I imagine now it's a problem of Domoticz.

                  I did change all my logic. NOw on startup and every X minutes, the node send to the Domoticz the status of relay, to mantain it in sync.

                  Errrr...... the status is received but not displayed correctly :disappointed_relieved:

                  I attach an image to explain better.

                  Domoticz is last update version, this is the current sketch:

                      @gohan Totally not updated. I did upload just now the @boots33 sketch in synch and it works. So it is my fault... But I cannot find!

                      I re-start from fresh (err.. from boots sketch).
