Hi,
after updating Home Assistant to 2025.9.2 (and still in 2025.9.3), my Nanoleaf bulbs connected via Thread through the HomeKit Controller integration stopped working.
All devices show up as unavailable in Home Assistant.
They do not respond to any commands (on/off, brightness, color, etc.).
Rolling back to 2025.9.1 restores full functionality.
So it looks like a regression introduced in 2025.9.2.

Has anyone else experienced this issue with HomeKit Controller and Nanoleaf Thread bulbs or any other accessories via homekit?
If you believe you have found a bug and your discussions here have people agreeing with you (It’s not currently working as designed) then you should check the issues. If it is working as designed and you just don’t like it, then look at the Feature Request Category for more info.
If there is already an issue for it, add a thumbs up to help push the effort along. If there is not an issue open for it open one.
It’s good to discuss and verify that there is an issue here, but if you want the appropriate developer to look at it & maybe get it resolved, it will have to be seen as an issue…
Same issue here. I re-paired all nanoleaf bulbs but it’s really slow. And now reverting back to 2025.9.1 does not help because of re-pairing… So stuck here until next release to recover control over HomeKit devices. Hope it will be soon. Meanwhile, I am back to manual control.
I am also experiencing this problem with the Homekit Integration after updating from 2025.9.1 to 2023.9.3. It is preventing my Honeywell T9 thermostat from functioning.

Same issue here… .been pulling my hair over my Nanoleaf/SecretLab Magnus Desk Strip and wondering why the entity was gone…
Tried a 2025.9.1 backup but that still didn’t work somehow (probalby because I paired and unpaired the damn thing a bunch of times in between…)
