Switching light groups of light groups very slow since recent updates

[Maddosaurus]

The problem

Since recent updates, HAss reacts extremely slow when switching light groups that contain other light groups.
All of my lights (Ikea Tradfri) are integrated via deconz (ConBee II) and are working as usual with minimal delays.
I have defined light groups via configuration.yaml that contain other groups (see snippet for original config):

• Group "All"
  • Group "Kitchen"
  • Lamp 1
  • Lamp 2
  • ....
  • Group "Living Room"
  • Lamp n
  • Lamp n+1
  • ...

Switching the daughter groups (e.g. Kitchen) works instantaneous. Switching the "All" group used to be instantaneus as well, but now takes 5 - 15 seconds. It doesn't matter if the group is triggered by the UI or a remote, it will always take a long time.
On top of that, I have also noticed that the UI is sluggish in updating the status of the "All" group when toggling it.
This is not the case for daughter groups - these update instantly.

Observed behaviour:

1. Toggle Group "All"
2. Observe Toggle in dashboard switching
3. 5-15 seconds later, all the lamps in the dashboard are updated and are actuated (turned on or off)

Steps to debug:

• Limit group membership of "All" to 1 daughter group (same problem with any daughter group)
• Replace daughter groups with the lamps that are contained in daughter groups

When removing the daughter groups out of the "All" group and adding all the lamps that are contained in the daughter groups directly into the "All" group, everything works instantaneously (basically, with the same speed like it was in 2021.12.10 with the original group setup)

Example YAML snippet

# configuration.yaml

# Custom light groups
light:
    - platform: group
      name: Living Room (L)
      entities:
        - light.computer_lamp
        - light.couchlampe
    - platform: group
      name: Kitchen (L)
      entities:
          - light.led_bar_60cm
          - light.coffe_counter
    - platform: group
      name: All (L)
      entities:
          - light.living_room_l
          - light.kitchen_l

Anything in the logs that might be useful for us?

Additional information

Resolving the daughter groups and adding the very same lights directly into the "All" group leads to instant switching and UI updating, basically the same speed as HAss had before the latest updates.
This is the temporary "fixed" config I'm running now:

# Custom light groups
light:
    - platform: group
      name: Living Room (L)
      entities:
        - light.computer_lamp
        - light.couchlampe
    - platform: group
      name: Kitchen (L)
      entities:
          - light.led_bar_60cm
          - light.coffe_counter
    - platform: group
      name: All (L)
      entities:
          # Kitchen
          - light.led_bar_60cm
          - light.coffe_counter
          # Living Room
          - light.computer_lamp
          - light.couchlampe

Hey there @kane610, mind taking a look at this issue as it has been labeled with an integration (deconz) you are listed as a code owner for? Thanks! _{^{(message by CodeOwnersMention)}}

Seeing the automation flagging this as a deconz issue:
I would suspect this not to be a deconz issue, but more of a core issue, as the lightgroups seem to be the culprit.
I filled out deconz merely because this is how I control the lamps in these groups 😄

Hi everyone, I have replicated this issue with only LIFX bulbs. After updating to 2022.2.2, the light group—containing both individual bulbs and other light groups—exhibited the same behaviour.

The individual bulbs changed immediately, but the groups had a ~10 second delay.

Rolling back to 2021.12.10 is my current workaround as I would not like to alter this config.

[reaper7]

I have exactly the same problem but with esphome lights, zigbee light in a group reacts immediately but esphome lights (as well as the whole group) with ~5-10sec delay

[emufan]

There are a lot of issues already opened.

[Maddosaurus]

Sorry, for causing chaos. I was trying to find similar issues but didn't seem to have looked closely enough. I'd be fine to close this off as a duplicate to #65119 as this looks quite the same.

Hi,

same Issue.... I have only zigbe2mqtt light. If I toggle a light group all direct member are turned on imeditaley and all lights which are member of another group which is part of the group have a delay from about 15 seconds.

Hi, I'm experiencing the same issue, I think it's due to PR #63477

[lbouriez]

Same issue on my side since the last release

[Andrewpaps]

Yep, same issue on my end making scripts & scenes extremely slow to react.

[casual-programmer]

I'm having the same problem with Philips WiZ bulbs, started with 2022.2 and continuing through 2022.2.3. The problem occurs with any action that is taken on a nested light group. There is a 10 second delay between the trigger and action, and then the action slowly makes its way through each light group within the nested light group.

[emufan]

Is anyone aware, how to get a core topic owner to this problem and opened issues, as there are now a lot of them and none of them has a code owner assigned to have a look.

Esp. as it is related to more groups, at least light groups and cover groups and more issues will follow, if more user will update.

[lbouriez]

Maybe @frenck can help :)

[torbjorn2000]

I got the same issue, and it is very easy to replicate.

This is the group config:

light:
  - platform: group
    name: test_group_1
    entities:
      - light.test_group_2
  - platform: group
    name: test_group_2
    entities:
      - light.bedroom_light_bulb

Switching light.test_group_2 is immediate while light.test_group_1 takes 10 seconds.

[jasondefuria]

I have the same issues presented here. It seems like the nested groups are the problem. @torbjorn2000 provides an excellent test case to help debug why this is occurring.

[tomasbedrich]

Confirming. I have mixture of Shelly, Zigbee2MQTT and Skydance lights. After manually flattening all the light groups, they react withing 1-2 seconds. With nested groups, it sometimes took 5-10s.

Nothing in logs unfortunately. The issue started in 2022.2.x.

[mmkrysiak]

Same issue on my side since. core-2022.2.5. It takes about a minute to turn off triple nested group of lights.

[balloob]

It's not part of 2.5. It will be part of 2.6
