Problems with Hue Emulation an Color Temperatur of the CCT Color and device not responding

Hi, I have a problem with two RGB CCT lights an HUE Emulation. One is flashed with tasmota and one with esphome. I want to control them with Alexa over Hue Emulation. I added this in the configuration

emulated_hue:
  listen_port: 80
  host_ip: 192.168.1.1
  off_maps_to_on_domains:
    - script
    - scene
  expose_by_default: false
  entities:
    light.yeelight_light_ceiling20_ceiling_light:
      name: "Yeelight Licht"
      hidden: false
    light.yeelight_light_ceiling20_ambient_light:
      name: "Yeelight Farbe"
      hidden: false
    light.yeelight_light_ceiling20_night_light:
      name: "Yeelight Nachtlicht"
      hidden: false
    light.tasmota_44237c37847e_light_light_1:
      name: "Esstisch Licht"
      hidden: false
    light.esstisch:
      name: "Esstisch Farbe"
      hidden: false

now I have multiple devices, but no color selection for the CCT Light

the http://192.168.1.1/api/pi/lights returns:

}

The type “Color temperature light” is correct, isn’t it ? I have also the message in the Alexa app for the 5 devices that the connected device is not responding (orig. German “Gerät reagiert nicht”)


If I change something in the Alexa app, it will change the state or switch the light part.

So where is there the bug, Alexa, hue emulation, configuration or is this still not possible ?
