This affects me too:
The code below has worked for a good few years. I had to take both “transition” and “color_name” out of set_state and use in the turn_on method to get it to work for testing. I don’t want to really do that as a permanent solution as it would be a significant amount of rework.
I checked the breaking changes for the last few releases and didn’t see anything.
The code below no longer works.
## Night state
- id: state_set_light_mode_night
alias: 'Set light state mode - night'
trigger:
- platform: state
entity_id: input_select.house_light_state
to: 'Night'
action:
- service: lifx.set_state
data:
entity_id: group.kitchen_night_lights
color_name: red
brightness: 65
# transition: 10
