WLED Turn Effect on with Brightness

Hi! I am trying to turn my WLED strip on with a sunrise effect with a specific brightness, but apparently the WLED integration (WLED - Home Assistant) doesn’t work with the brightness field.
Is there a way to do it without having to call the turn.on service (and without having the light turning on and quickly changing state) with the desired brightness before?

Thanks!

There are very few light platforms that allow altering the brightness while the light is off. WLED is not one of them.

This works for me. light.ensuite_lights is a group of two lights, one of which is a WLED strip.

            - service: light.turn_on
              data_template:
                entity_id: light.ensuite_lights
                brightness_pct: "{{ state_attr('switch.adaptive_lighting_ensuite', 'brightness_pct') | int }}"
                rgb_color: "{{ state_attr('switch.adaptive_lighting_ensuite', 'rgb_color') }}"
                white_value: 0

With that I don’t get any initial brightness etc from the previous on state.
