    @ostoja said in Multiple Relays + Motion sketch, fully customizable, optional timer, manual override:

    // Present all sensors to controller
      for (int i=0; i<numSensors && i<MAX_ATTACHED_DS18B20; i++) {   
         present(i, S_TEMP);
      }
    
      // Register all sensors to gw (they will be created as child devices)
      for (int sensor = 1; sensor <= NUMBER_OF_RELAYS; sensor++) {
        present(sensor, S_BINARY, "Relay", ack);
      }
    

    With this two "for" loops you set present(n) multiple times. in the first for() you start with 0 until MAX_ATTACHED_DS18B20-1, in the second for() you start with 1 until NUMBER_OF_RELAYS-1, so this will assign the sensors with identical IDs as the relays.
    I have not checked the internal code of this method, but I would think that you should better user a different range in the second for() loop starting at least with MAX_ATTACHED_DS18B20+1.

      Additional remarks:
      For the relays better start with 1.
      Shift the Temp values to higer range (use e.g. a variable like FRIST_DS_SENSOR_ID).
      Check, if the receive()-part and the ID you get really fits together with the relay you want to switch.
      Don't try to read the temperature values every few parts of a second. Use a millis()-routine.

      Please search the forum, there have to be at least 2 threads with exactly the same problems in which I posted how to solve this. You are "trying to reinvent the wheel". :grin:

        I commented out the "sleep", but when I press the relay switch in Domoticz, it does not work:white_frowning_face:

          @HenryWhite thank you for the excellent sketch. It works like a charm in my HA configuration!
