Heatpump Sketch Help

  • Hi,

    I need some help converting the Heatpump sketch example to 2.0 and also isolating to just the Mitsubishi model as i have no need or memory for all the models.... i guess my biggest issue is where in the sketch is the model actually defined?

    Link to sketch that i need converting below:

    @SGi - check this out: https://forum.mysensors.org/topic/4276/converting-a-sketch-from-1-5-x-to-2-0-x

    In the sketch it looks like you just define which you want to use:
    Just remove/erase the ones you dont want.

    #include <FujitsuHeatpumpIR.h>
    #include <PanasonicCKPHeatpumpIR.h>
    #include <PanasonicHeatpumpIR.h>
    #include <CarrierHeatpumpIR.h>
    #include <MideaHeatpumpIR.h>
    #include <MitsubishiHeatpumpIR.h>
    #include <SamsungHeatpumpIR.h>
    #include <SharpHeatpumpIR.h>
    #include <DaikinHeatpumpIR.h>```

  • Ok, i have managed to get a heatpump IR sketch working somewhat. I can see the node in 'hardware' and even the children but they do not appear in 'devices'... is there something fundamentally wrong in my sketch?

    I am using Domoticz and a RPI controller.

    @SGi - you will not see any device before first value is sent. Make sure you send status or something on startup.

  • @sundberg84 Ok thanks, i thought the following part of the code in Presentation() was doing that?

    // Load our values on start
      POWER_STATE = loadState(POWER_ID);
      TEMP_STATE = loadState(TEMP_ID);
      FAN_STATE = loadState(FAN_ID);
      MODE_STATE = loadState(MODE_ID);

    @SGi - not sure, but I think that is load the saved state from EEPROM.
    You should have some sort of send(value);

  • I can see the topic is quite old but myabe a complete sensor 2.1 example?
    I can see that this code for openhab is quite popular. But i'm facing an issue constructing the proper MQTT topic
    As on my set up all my control messages look like

          topic: "mys-in/41/2/1/0/2"
          payload: "0"

    So wonder which ones to use with this sketch?
