IKEA light on Hue hub, scene doesn't change brightness

Third party integrations

Hey there,

I have the exact same problem.
Even using the scenes from the official Hue app, some bulbs will end up not reacting . . . and it will even go as far as messing with the Hue scene.
The scene will end up in the broken state and that broken state will be saved as the new value for the Scene.

Huge disappointment on that part, but I think it’s on the Zigbee driver side of thing.
What seems to happen is that the Tradfri / Ikea bulbs discard a new command if they are doing something.
Doing something I mean transitioning either color or brightness.

Say it takes 5s to transition from white to yellow, any command sent during that timespan will be discarded. It’s a guess, but an educated one, after spending hours trying to debug that :slight_smile:

The solution I found to have reliable scene activation 100% of the time is to:

  • Use scripts instead of scenes
  • Split the calls between setting the brightness and setting the level
  • Explicitly specify the transition time (in seconds)
  • Add a delay between the 2 actions equal to the transition time

It looks like this:

alias: Evening Scene
sequence:
  - service: light.turn_on
    data:
      entity_id: group.living_room
      brightness: 102
      transition: 1

  - delay:
      seconds: 1

  - service: light.turn_on
    data:
      entity_id: group.living_room
      color_temp: 450
      transition: 1

But still I would love to see a fix for this, it’s actually a huge deal having to go through such complexity for such a simple action.

In any case, if that helps someone, it’s somethings :slight_smile:
