Cannot dim emulated hue light

Third party integrations

I’ve created an ESPHome device which controls a dimmable light with temperature. This can be controlled without problems from the UI.

I’ve enabled the emulated hue support in HA and everything seems to be working fine, except one small issue. I can switch Tasmota plugs on and off and even my led panel. However, Alexa does the action for the led panel and says “panel 1 isn’t responding. Please check it’s network and power supply”. Dimming or color temperature does not work: “panel 1 doesn’t support that”.

    "name": "Panel 1",
    "state": {
      "colormode": "ct",
      "ct": 333.0,
      "mode": "homeautomation",
      "on": true,
      "reachable": true
    },
    "swversion": "123",
    "type": "Color temperature light",
    "uniqueid": "xxxxxx"
  }

Is there something extra that needs to be configured in ESPHome? I suppose not, since the emulation is done by HA.
