Scenes no longer transitioning over time?

Hey Everyone,

I’ve had a scene transition option running for more than a year, but recently it doesn’t transition. Instead, the scene is instantly applied. The devices involved are Hue bulbs and that’s it. It’s worked in the past and I was only recently informed that it hasn’t worked for more than a few weeks.

What could be wrong? What could have changed? How do I fix it?

Here is the automation:

type: button
tap_action:
  action: call-service
  service: scene.turn_on
  service_data:
    transition: 60
  target:
    entity_id: scene.david_blue_lights
show_icon: false
name: Wake
hold_action:
  action: none

Here is the scene definition:

I don’t have an answer unfortunately, but I’m experiencing this now as well. Scene transitions seem to be falling back to the hue firmware default transition time.

I guess I’m glad it’s not just me. :grinning_face_with_smiling_eyes: Should we make a bug report?

I won’t have access to my computer to pull logs for a couple days, but seems an issue is in order. As best as I can tell, transition times are not currently respected for turn_on commands, but still work fine for off. Only have hue bulbs to try this, but there’s an open issue for lifx lights that sounds similar: LIFX Cloud integration ignores transition times from `scene.turn_on` · Issue #69829 · home-assistant/core · GitHub

Ok, I put in a bug report about it. Hopefully it will get noticed and resolved. Thanks!
