Dimmer LED with two state

[jacek]

I did something like that based on DimmableWithRotaryEncoderButton, I changed only this part :

void incomingMessage(const MyMessage &message)
{
  if (digitalRead(8) == 0) { persons = 0;} else {persons = 1;}
  if (message.type == V_LIGHT && persons == 1) {
    // Incoming on/off command sent from controller ("1" or "0")
    int lightState = message.getString()[0] == '1';
    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
    gw.send(dimmerMsg.set(newLevel), true);
    // We do not change any levels here until ack comes back from gateway 
    return;
  } else if (message.type == V_DIMMER && persons == 1) {
    // Incoming dim-level command sent from controller (or ack message)
    fadeTo = atoi(message.getString(convBuffer));
    // Save received dim value to eeprom (unless turned off). Will be
    // retreived when a on command comes in
    if (fadeTo != 0)
      saveLevelState(EEPROM_DIM_LEVEL_SAVE, fadeTo);
  }
 if (persons == 1){
       saveLevelState(EEPROM_DIM_LEVEL_LAST, fadeTo);
       Serial.print("New light level received: ");
       Serial.println(fadeTo);
     if (!changedByKnob) 
       knob.write(fadeTo); 
       // Cancel send if user turns knob while message comes in
       changedByKnob = false;
       sendDimValue = false;
       // Stard fading to new light level
       startFade();
} else if (persons == 0){
 
  gw.send(dimmerMsg.set(0), true);   
 return;
  }
}

What I wanted to get?
I wanted to achieve the effect such that when the variable persons = 1 ściamniacz operate normally, but the variable persons = 0 despite the switch is turned on in domoticzu it is to be shut down after a while or at all does not turn on . Now, this code works like that sometimes acts like he wants and sometimes not :(
Sometimes works well like now:

read: 0-2-4 s=1,c=1,t=3,pt=0,l=2,sg=0:27
send: 4-4-2-0 s=1,c=1,t=3,pt=2,l=2,sg=0,st=ok:0
read: 0-2-4 s=1,c=1,t=3,pt=2,l=2,sg=0:0
send: 4-4-2-0 s=1,c=1,t=3,pt=2,l=2,sg=0,st=ok:0

but sometimes dont work well:

read: 0-2-4 s=1,c=1,t=3,pt=2,l=2,sg=0:0
send: 4-4-2-0 s=1,c=1,t=3,pt=2,l=2,sg=0,st=ok:0
read: 0-2-4 s=1,c=1,t=3,pt=0,l=2,sg=0:33
send: 4-4-2-0 s=1,c=1,t=3,pt=2,l=2,sg=0,st=ok:0

and I donot know why :(
the point is that in the read is different than 0 in domoticzu button does not become inactive .

OK, i think it work's well now:

} else if (persons == 0){
  if (message.getString() != 0) 
          {gw.send(dimmerMsg.set(0), true);}
   else
          {return;} ```
