WTH is restoring scene snapshots for light groups still not working properly?

As the title says: WTH is this issue still not being resolved?

Scenes with a light group snapshot do not activate correctly

opened 11:59AM - 19 Sep 24 UTC

integration: hue

### The problem This is a follow-up for #122165 which has been fixed & closed, …but I think something is still not working correctly. I have an automation that creates a scene using a snapshot, dims the lights, and reactivates the scene later on (to dim the lights while the balcony door is open). In my specific case, they are all Hue lights. When I create the scene as a snapshot of a light group (with each light having a different color), activating the scene turns on the lights, but sets them all to the same (white, for me) color instead of the correct individual settings. If, however, I create the scene specifying the individual lights rather than a light group, everything works correctly. I am attaching an automation that I can trigger manually to reliably reproduce the issue. ### What version of Home Assistant Core has the issue? core-2024.9.2 ### What was the last working version of Home Assistant Core? _No response_ ### What type of installation are you running?

Scenes are an elementary feature for lights and it would be nice if this issue could get a little bit more priority

It’s not seen as an issue, marcel described what you need to do when restoring states. For different light levels and colors, you need to list out each light in the light group. The group combines all light values together and the scene only see’s the top light and it’s combined settings.

Yeah, would be a workaround if it actually would work, but it clearly does not.
Actually it does not even matter if you choose the light group or if you choose the specific lights, the result is always that the light color and brightness does not match the state before/after the snapshot was being taken.

Assuming you are using a native light group and not one that syncs all lights (which would also mess things up), this sounds more like a problem with the intagration controlling your lights. If so, only the integration builder has a hope of fixing this.

Well, playing around again I now found out that when I take the light’s scene snapshot, then start effects via MQTT: Publish (zigbee2mqtt topic, in my case) and then restore the snapshot, the issue mentioned above occurs.
If I use the same effects via Device/Effect option, the snapshot gets restored as intended.
Weird, but yes, I guess you were right somehow. The issue is dependent on the light steering method used after the snapshot has being taken.
