Hi, not sure exactly with which version it occurred, but recently i started missing the brightness feature on my dual channel dimmer.
I now just shows as a switch…
These are the state attributes reported:
supported_color_modes: []
color_mode: unknown
friendly_name: Light Bar
supported_features: 8
Funny thing is, i have 2 single channel dimmers set up in the same way, and they still behave normal:
supported_color_modes:
- brightness
friendly_name: Light TV Room Ceiling
supported_features: 40
I suspect it has something to do with
- Color mode implementation esphome#2012 by @oxan (notable-change) (breaking-change)
I use this yaml, which is almost identical two the single channel (except it is for dual channel):

Is this a bug, or should i change my configuration?
If the latter…what to change??
