Dimming light groups via Alexa (no cloud) not working

Hi together,

i grouped my lights in the lights.yaml to one device

- platform: group
  name: "Bürodeckenlicht"
  unique_id: buerodeckenlicht
  entities:
    - light.buro_deckenlicht_1_level_on_off
    - light.buro_deckenlicht_2_level_on_off

and then i include them to my alexa.yaml like this:

smart_home:
  locale: de-DE
  endpoint: https://api.eu.amazonalexa.com/v3/events
  filter:
    include_entities:
      - light.baddeckenlicht

but my alexa said she cannot dim them - on / off is working.

Someone a idea whats wrong?

I’m having a similar issue (using Home Assistant Cloud for the Alexa integration). Have you figured anything out on this?

Had something similar this week and I’m still trying to figure it out.
