Data for turn_on and turn_off

Configuration
1

Hello,

I’ve simple automation that turn on/off a light :

- alias: Light HUE RDC
  description: ''
  trigger:
  - platform: state
    entity_id: switch.din_rail_dimmer
  action:
  - service: "light.turn_{{ trigger.to_state.state }}"
    target:
      entity_id: light.entree_entree
    data:
#      brightness: 255
      transition: 1

I would like to set specific data value for turn_on (brightness = 255 and transition = 1) and other data for turn_off (transition = 5).

What is the best way to do that ?

Thank you very much.

action: light.turn_{{ trigger.to_state.state }}
data: |
  {{ {"brightness": 255, "transition": 1} if trigger.to_state.state == "on" else {"transition": 5} }}
target:
  entity_id: light.entree_entree

Thank you very much !

But with settings, the light ‘light.entree_entree’ does not turn on anymore (the transition = 5 work fine when turn off).

I had a typo… brightness_pct instead of brightness. I have fixed it above.
