Example script for changing color temp using the left and right buttons;

Yaml script for the left button:

service: light.turn_on
target:
  entity_id: light.hanglamp_keuken
data:
  color_temp: >
    {{ state_attr( 'light.hanglamp_keuken', 'color_temp' ) | default( 0, True
    ) | int + 50 }}

Yaml script for the right button:

service: light.turn_on
target:
  entity_id: light.hanglamp_keuken
data:
  color_temp: >
    {{ state_attr( 'light.hanglamp_keuken', 'color_temp' ) | default( 0, True
    ) | int - 50 }}

The default(0,True) sets the value to zero, True is required to make it work. This is because sometimes when powering the lamp on for the first time the color_temp value is None and not an int.

I’m looking for a way to remove the manual entity_id, I tried !input “light” or this.entity_id but that doesn’t seem to work.

I hope this helps someone.
