How do I get Transition to work on a Wiz Light Bulb?

Configuration
1

Hello,
Wondering if anyone is able to help me with an issue I am having trying to get transition to work on a wiz light bulb. The problem I am having is that any scene or script that I have written does not transition the brightness of the bulb. It will only immediately turn it on. I’m able to transition the bulb using the Wiz Smart Phone App by using the Apps ‘fade in/out’ feature. However, when attempting to get the state of the bulb, or attempting to add transition to a scene, it will not work whatsoever.

Has anyone had this issue and was able to solve it?

Thanks in advance.

Current Home Assistant Version: 2022.11.1

If the bulb supports a transition parameter and it is not working you can open an issue here:

Please include an example of the configuration you used that is not working.

Hello,

Thank you very much for responding to my post.

Here is a YAML scene I have attempted to use to transition the bulb.

Appreciate it.

I too am trying to figure this out, please let me know if you make any progress on this!

According to the integration github (GitHub - sbidy/wiz_light: A WiZ Light integration for Home Assistant), the API doesn’t support transition time for power on/off. But since it supports effect speed it may be possible to set transition times between color/brightness.

What is declined or rejected:

  • Change of the speed of the transition from on to off and off->on. This is not supported via the UDP API and can only be configured via WiZ App.

Hello,

I wasn’t able to find anything on resolving the transition effect. However, I was able to get a workaround going with some scripting to slowly increase the brightness. Have provided the below if it is beneficial for you at all. Basically, it will turn on lights at a low setting and then slowly transition the bulbs to almost being at full brightness. Hope it helps. Thanks.

alias: Wake Up Lights
sequence:
  - service: light.turn_on
    data:
      effect: Daylight
      brightness_pct: 1
    target:
      entity_id: light.bedroom_lights
  - repeat:
      until:
        - condition: state
          entity_id: light.bedroom_lights
          state: "on"
      sequence:
        - service: light.turn_on
          data: {}
          target:
            entity_id: light.bedroom_lights
  - repeat:
      until:
        - condition: numeric_state
          entity_id: light.bedroom_lights
          attribute: brightness
          above: 225
      sequence:
        - service: light.turn_on
          data:
            brightness_step_pct: 1
          target:
            entity_id: light.bedroom_lights

Hi, i found your posts here very helpfull to make a script for a sunset and added some color temp effect to it. Hope someone find this helpfull.

alias: wiz_control

sequence:
  - service: light.turn_on
    data:
      color_temp: 450
      brightness: 1
    target:
      entity_id: light.deckenleuchte_buro

  - repeat:
      until:
        - condition: numeric_state
          entity_id: light.deckenleuchte_buro
          attribute: brightness
          above: 254
      sequence:
        - service: light.turn_on
          data:
            brightness_step_pct: 1
          target:
            entity_id: light.deckenleuchte_buro
        - delay:
            hours: 0
            minutes: 0
            seconds: 9
            milliseconds: 0
        - if:
            - condition: numeric_state
              entity_id: light.deckenleuchte_buro
              attribute: color_temp
              above: 238
          then:
            - service: light.turn_on
              data:
                color_temp: '{{states.light.deckenleuchte_buro.attributes.color_temp - 4}}'
              target:
                entity_id: light.deckenleuchte_buro

mode: single

One more example with another effect. Here ist the brightness increasing to the fully value before the color starts to shift to daylight. That gives the sunset effect more color during the run. Hope you enjoy it!

alias: wiz_control
sequence:
  - service: light.turn_on
    data:
      color_temp: 450
      brightness: 1
    target:
      entity_id: light.deckenleuchte_buro
  - repeat:
      until:
        - condition: numeric_state
          entity_id: light.deckenleuchte_buro
          attribute: brightness
          above: 254
      sequence:
        - service: light.turn_on
          data:
            brightness_step_pct: 1
          target:
            entity_id: light.deckenleuchte_buro
        - delay:
            hours: 0
            minutes: 0
            seconds: 8
            milliseconds: 0
  - repeat:
      until:
        - condition: numeric_state
          entity_id: light.deckenleuchte_buro
          attribute: color_temp
          below: 239
      sequence:
        - service: light.turn_on
          data:
            color_temp: "{{states.light.deckenleuchte_buro.attributes.color_temp - 1}}"
          target:
            entity_id: light.deckenleuchte_buro
        - delay:
            hours: 0
            minutes: 0
            seconds: 3
            milliseconds: 0

Frustrating that the Wiz bulbs don’t support transitions through home assistant - seems a pretty generic feature of smart bulbs.
But thanks for these scripts, they’re doing the job nicely.

Sorry to necro this thread but I just experienced this with some floor lamps I added to my bedroom scenes. I have a gradual transition of 10s at various times of the day.

I was able to get it to work by setting up the globe with Matter instead of the WiZ integration. This seems to be working perfectly. The only thing I no longer have is light effects but I don’t remember the last time I ever used those.
