How to use lights as notification - create scene?

1

Hi there,

I am pretty new to this community and already blown away - already a big thank you to everyone!

I am struggling with a set-up I am trying to implement.
I have a sensor triggering when my washing machine is done. I wanted to play around to also add some light notification (flash and then going back to the state it was).

First, I created a group for the lights I want to flash.
Then I wrote two scripts “scene.create”, where the first one creates a snapshot of the Group and the second withe the desired color.
In my automation I then call the two scenes in a sequence.

Unfortunately, it seems the color information of my hue lights are not considered when using “snapshot”.

alarm_lights_create_scene:
  mode: single
  sequence:
    - service: scene.create
      data: 
        scene_id: alarm_lights_red
        entities: 
          group.alarm_lights:
            state: on
            rgb_color: [255,0,0]
            brightness: 255
            transition: 1

            
alarm_lights_backup_scene:
  mode: single
  sequence:
    - service: scene.create
      data:
        scene_id: alarm_lights_before
        snapshot_entities:
          - group.alarm_lights

Any ideas how to solve this?
Thanks in advance
