Hue light brightness level incorrect when using transition_time #108234

Closed mcmd1962 closed 3 months ago

mcmd1962 commented 5 months ago

The problem

The brightness level reported for a hue light when using a transition period is reporting the end value for the transition and not the current brightness level. A nano leaf type light is behaving as expected. The command used to test this: light.turn_on called with service_data={'entity_id': ['light.hue_light', 'light.nanoleaf'], 'brightness': 200, 'transition': 15}

In this period asking every 2 seconds for the brightness level shows: 13:54:21.376 [service_test_brightness] entity_id=light.hue_light brightness=200 lu=2024-01-17 12:54:20.059762+00:00 lc=2024-01-17 12:39:32.604282+00:00 13:54:21.377 [service_test_brightness] entity_id=light.nanoleaf brightness= 30 lu=2024-01-17 12:54:20.556465+00:00 lc=2024-01-17 12:39:39.619442+00:00 13:54:23.379 [service_test_brightness] entity_id=light.hue_light brightness=200 lu=2024-01-17 12:54:20.059762+00:00 lc=2024-01-17 12:39:32.604282+00:00 13:54:23.380 [service_test_brightness] entity_id=light.nanoleaf brightness= 58 lu=2024-01-17 12:54:22.977432+00:00 lc=2024-01-17 12:39:39.619442+00:00 13:54:25.382 [service_test_brightness] entity_id=light.hue_light brightness=200 lu=2024-01-17 12:54:20.059762+00:00 lc=2024-01-17 12:39:32.604282+00:00 13:54:25.383 [service_test_brightness] entity_id=light.nanoleaf brightness= 71 lu=2024-01-17 12:54:24.187046+00:00 lc=2024-01-17 12:39:39.619442+00:00 13:54:27.386 [service_test_brightness] entity_id=light.hue_light brightness=200 lu=2024-01-17 12:54:20.059762+00:00 lc=2024-01-17 12:39:32.604282+00:00 13:54:27.387 [service_test_brightness] entity_id=light.nanoleaf brightness= 96 lu=2024-01-17 12:54:26.608352+00:00 lc=2024-01-17 12:39:39.619442+00:00 lu=last_updated lc=last_changed

As you can see here the hue_light always reports 200 for brightness while the nanoleaf reports the current value.

The python logic used to test this: entity_ids = [hue_light, nanoleaf] light.turn_on(entity_id=entity_ids, brightness=20, transition=0.6) task.sleep(1.5) light.turn_on(entity_id=entity_ids, brightness=200, transition=15) for entity_id in entity_ids: st0 = state.get(entity_id) lu = st0.last_updated lc = st0.last_changed st = state.getattr(entity_id).get('brightness') log.info('brightness=%s lu=%s lc=%s', st, lu, lc)

Hey there @balloob, @marcelveldt, mind taking a look at this issue as it has been labeled with an integration (hue) you are listed as a code owner for? Thanks!

Code owner commands Code owners of `hue` can trigger bot actions by commenting: - `@home-assistant close` Closes the issue. - `@home-assistant rename Awesome new title` Renames the issue. - `@home-assistant reopen` Reopen the issue. - `@home-assistant unassign hue` Removes the current integration label and assignees on the issue, add the integration domain after the command. - `@home-assistant add-label needs-more-information` Add a label (needs-more-information, problem in dependency, problem in custom component) to the issue. - `@home-assistant remove-label needs-more-information` Remove a label (needs-more-information, problem in dependency, problem in custom component) on the issue.

This is by design for Hue lights. Nanoleaf implemented in between state reports with the values while transitioning but Hue does not, sorry.

If this is not what you expect it to be, maybe file a feature request with Hue ?

Closing as issue here as this works as expected by design, we just follow whatever the Hue api tells us.
