Light bootup brightness

i lately installed esphome on an LSC light.
i got it up and running and am using it in domoticz

when i switch on the light i want it to go to 80% ww brightness
this works nut the slider in domoticz shows 100%
it is switching to 80% but still comunicates 100% to the outside world through MQTT

this is what i see in MQTT
204 is the 80% ww brightness but i do not know where the 255(100% is coming from)

{"effect":"None","effect_index":0,"effect_count":7,"color_mode":"cwww","state":"ON","brightness":255,"color":{"c":0,"w":204}}

this is my yaml code

esphome:
  name: douchelamp
  friendly_name: douchelamp

  on_boot:
      priority: 750.0  
      then:
        - light.turn_on: 
            id: douchelamp
            color_brightness: 0%
            warm_white: 80%
            cold_white: 0% 
            red: 0 %                      
            green: 0%

            auto call = id(douchelamp).turn_on();
            // Transtion of 1000ms = 1s
            call.set_transition_length(1000);
            if (state == 0) {
              call.set_brightness(1.0);
            } else {
              call.set_brightness(0.01);
            }
            call.perform();
            state += 1;
            if (state == 2)
              state = 0;

So where in your code you do this mqtt communication for 80% brightness?

i communicate warm_white:80% but 100% is send out.
i already solved the problem myself
i added Brightness:80%
