#Matter over Thread devices disconnecting from HA but remain connected in HomeKit & the vendor apps?

I’ve just started with HA and one thing I’m noticing is that some of my Matter (seems like Matter over Thread devices right now) are randomly showing as unavailable. It seems to be related with Apple Thread networks, right now it seems to be happening to my NanoLeaf Essentials smart lights, my Eve Energy plugs, and my Aqara P2 Door & Window sensor - all Matter over Thread devices.

What channel should I go into in order to gather more information on what’s going on, potential fixes I can do, and find any updates from HA/Matter developers about the topic?

The devices in question all remain connected with no issues in their respective NanoLeaf/Eve/Aqara apps as well as via HomeKit.

#

Removing/repairing the devices seemed to bring the connection back up but I’d rather not do this daily and fix my automations every time.

Bump.

I have a similar issue as well. My Matter devices (Aqara P2 Sensors) keep going offline in python-matter-server, so I decided to remove the ghost entities and re-add everything. I cannot add them back to my network though. They can be added in the Aqara app, but when adding directly in HA, it says something went wrong with the logs stating:
2025-11-19 12:56:58.733 (Dummy-2) CHIP_ERROR [chip.native.SC] PASESession timed out while waiting for a response from the peer. Expected message type was 33

@tidal vortex : Do I get it right that you have paired these devices with both Matter Controllers/Fabrics (Apple, HA) at the same time? If so, for the affected devices, which one is their primary fabric (meaning, to which controller did you pair with the original device QR code, and which one did you share to)?
