Use long transition time on Hub Bridge v2

Hi all,

Is it possible to set a transition time longer than 10 minutes with Hue Bridge v2? Whenever I set the transition longer than that, the attached automation fails. If I use some value less than 600, it works flawlessly.

alias: test
description: ""
trigger:
  - platform: time
    at: "06:00:00"
condition: []
action:
  - service: hue.activate_scene
    data:
      transition: 1200
    target:
      entity_id: scene.myroom_honolulu
mode: single

The error message is

value must be at most 600 for dictionary value @ data[‘transition’]

I nailed down the limit is set by:

I’m aware that Hue v2 API uses milliseconds instead of seconds. The maximum value was 65535 (in seconds) in v1, but the official API reference says the max is now 21600000 (6 hours). So not sure why we have 600 seconds limit.

Thanks :slight_smile:

I too have been struggling with the same error language when attempting an Activate Hue Scene with a transition longer than 600 seconds. I have mucked about in mostly quite old forum entries on the topic but so far have not managed to overcome this particular error.

I too would love to access longer transitions, whether through an official fix or a customization.
