Hi folks,
i am struggling setting up a light group.
I have 3 Träfri bulbs and want to control them together.
I have set up a light group in the configuration.yaml
# Wohnzimmer Licht Gruppe
light:
platform: group
name: Wohnzimmer Licht
entities:
- light.wohnzimer_1
- light.wohnzimer_2
- light.wohnzimer_3
I put a button to my Lovelace Dashboard but it says ‘not available’. I can neither turn it on or of nor can I change the brightness.
Any idea where I went wrong?
