Power on Transition Durations in Hue integration are broken

[thrillcat]

The problem

While power off transition durations work properly for all lights, my Hue light strip power on transitions have broken. Lutron lights still fade up to desired setting, but Hue lights turn on instantly.

I've tried rebuilding the scene, relaunching the integration and Home Assistant. Nothing seems to bring back the power on duration for Hue lights.

What version of Home Assistant Core has the issue?

core-2024.7.3

What was the last working version of Home Assistant Core?

Additional information

Have confirmed that all hue devices are up to date, Home Assistant is up to date (this may coincide with latest update I installed a week or so ago).

I've noticed this exact same behavior happening all of the sudden on my set up as well. Turn on commands ignore transition time.

This is probably related to #122165, due to a change in the Philips Hue API after a firmware update.

I've noticed this exact same behavior happening all of the sudden on my set up as well. Turn on commands ignore transition time.

@mark3apps Does it also ignore the temperature, like described in #122165?

[mark3apps]

Yes, for me it was also ignoring temp. I did find a workaround for the time being though. Found in another thread that removing effect: none from every scene seemed to fix the issue. I basically did a find and replace, restarted and at least for the moment, all my lights are back to normal and working.

[thrillcat]

I've removed 'effect: none' from all the scenes but it did not change the behavior. Transition time is still being ignored in turn on processes.

This started here immediately after a hue bridge update yesterday (BSB002 | 1.66.1966060010) @domibarton: Yes, temperature was ignored, too. Removing every effects: none from scenes.yaml "fixed" both.

[thrillcat]

None of the YAML edits worked for me but a week or two ago I ran an HA update and all is back to normal.
