Dimmer and automaticly turn "on" and "off" the light



  • Hello,

    I have dimmer code wchitch allow turn "on" or "off" the light from switch or domoticz when light level is ">" or "<" 350.
    I wont that light when is "on" and light level change from < 350 to > 350 light automaticly "off" and sen information to domoticz but I cant do that 😞
    I have something like this but this only send information to domoticz and no change lighgt status.
    Sorry this change light status but only from "on" to "off", when light level change to < 350 light turn "on" and I dont know why for a moment turn "off"

    
    void autolight()
    {
      if (analogRead(photoPin) > 350 &&  analogRead(LED_PIN) > 0)
      {//Turn "off" the light
        analogWrite(LED_PIN,0);
      
        gw.send(dimmerMsg.set(0), true);
                             return;
      }
      else if (analogRead(photoPin) < 350 &&  analogRead(LED_PIN) == 0)
      {// Turn "on" the light
        analogWrite(LED_PIN,100);
      
        gw.send(dimmerMsg.set(100), true);
                             return;
        }
    }
    void incomingMessage(const MyMessage &message)
    {
    if (message.type == V_LIGHT) {
      
      if (analogRead(photoPin) < 350) {
                       // Incoming on/off command sent from controller ("1" or "0")
                             int lightState = message.getString()[0] == '1';
                             int newLevel = 0;

                       // retreived when a on command comes in
                             if (fadeTo != 0)
                                    saveLevelState(EEPROM_DIM_LEVEL_SAVE, fadeTo);
      } else {

    @jacek In your icomingMessage routine, it looks you have no code to turn the light off, although I might be misinterpreting it.

  • Sorry it' s complite incomingMessages code:

    void incomingMessage(const MyMessage &message)

    if (message.type == V_LIGHT) {
      
      if (analogRead(photoPin) < 350) {

                             int newLevel = 0;
                                if (lightState==LIGHT_ON) {
                                   // Pick up last saved dimmer level from the eeprom
                                   newLevel = loadLevelState(EEPROM_DIM_LEVEL_SAVE);
                                } 
                       // Send dimmer level back to controller with ack enabled

    @jacek It looks like you have an endless loop to me,
    To initiate turning off the light due to a high ambient level, you call gw.send(dimmerMsg.set(0), true); which will instruct domoticz to send a command back which should be acted upon in your incomingMessage routine. In that routine, if the ambient light level is high, you send the same command back to domoticz: gw.send(dimmerMsg.set(0), true);. It's not clear to me what the rest of the functions after that do but they won't be executed due to your return command. What does the serial output show when high ambient light triggers this?

    @jacek As I mentioned, you call gw.send(dimmerMsg.set(0), true); again in the incomingMessage routine. By doing that, you are asking Domoticz to send another off command. Instead you should have a command there to actually set the dim level on the pins to the value that you want. I'm not too familiar with this code, but looking at it, you should just save the new state there and then continue with the routine, rather than calling return;

    Cheers

    @jacek By the looks of your code you're doing the following.

    1. Domoticz sends a command to your Node.
    2. You ignore the value and assign 0 as the value.
    3. You send the new value - which is allways 0 - to domoticz.

    So basically you turn off the lamp no matter what the command is what Domoticz is sending to the node.

    At least that's what I think. But I'm a bit tired have been studying for too many hours today 😉
