Transition for turn_off service doesn't work for Yeelight Lightstrip

Configuration
1

I have Yeelight Lightstrip YLDD01YL with firmware 1.4.1_34 and transition for light.turn_off service doesn’t work. I have in automation this service:

- service: light.turn_off
  entity_id: light.yeelight_lightstrip_sypialnia
  data:
    transition: 10

and lightstrip turns off without transition (it takes about 1 second).
My configuration for Yeelight component:

platform: yeelight
devices:
  192.168.2.220:
    name: yeelight lightstrip sypialnia
    transition: 500
    save_on_change: false
    use_music_mode: false

It’s hardware limitation or some issue with component/configuration?

I don’t think there is an issue as transition for Yeelight is specified in ms instead of seconds. https://home-assistant.io/components/light.yeelight/

Yes, in configuration of the component default transition is in ms. But in service turn_on/turn_off transition is in seconds.

For service turn_on with transition: 10 lightstrip turns on about 10 seconds. Only with turn_off there is a problem.

Missed that one… :grinning: I see several questions about it in the Yeelight topic @lambtho suggested to not use turn_off but set the brightness to 0 could be a good workaround.

I looked into it and it seems either transition on light_off action is not yet supported in HA for Yeelight or it is a bug. Transition brightness to 0 doesn’t work but this workaround does the trick I think;

    - service: light.turn_on
      entity_id: your.light_entity
      data:
        brightness: 1
        transition: xx
    - delay: '00:00:xx'
    - service: light.turn_off
      entity_id: your.light_entity

I have exactly the same code in automation :wink:
