Light.turn_on Color Transition

Hi All,

I’m using the light.turn_on service to change a light brightness and color when an automation is triggered. The brightness transitions appropriately but the color switches immediately. Does anyone have a way of making the bulbs color transition slowly as well?

data_template:
  brightness: 100
  rgb_color:
    - '248'
    - '3'
    - '252'
  transition: 10
entity_id: light.readinglight
service: light.turn_on

I’m using inovelli ilumin RGBW zwave bulbs.

Edited the main post - I was playing around with data templates to see if that would cause different behavior. Doesn’t change anything.

I’m guessing this depends on the type of light. My light colour transitions as expected (I use it in a sunrise simulation alarm clock).
