Matter unstable unless local TBR running

Configuration Matter/Thread
1

Hi,

I am using home assistant on a raspberry pi 5 and have a small thread network.

I have a Apple TV 4k and 2 homepod minis running the network.

All matter devices seem to drop of the network unless I run the OTBR add on but that in itself doesnt seem right looking at the logs (some attached) If i stop the OTBR add on the whole matter network becomes unstable.

Just looking at why the logs seem to point to it not working however in reality everything works perfect.

Drop off the thread network? If the addon isn’t running the network no longer exists.

Do you have them connected to Apple TV?

I’m pretty sure HA will need addon running to talk to the thread devices even with Apple TV. You should be able to use apples “home”(?) app to operate devices using Apple TV.

Sorry I should have clarified. My Apple thread network is preferred with the OTBR joined into it.

4

The last I heard, earlier in this year, having multiple TBRs makes connectivity unstable, and I understand that the Thread feature “TREL” is one of the main reasons for this. Whether this is the problem here, I don’t really know, just be aware of it.

5

Yeah I read about that too. What I’m confused about is the logs from the OTBR seems to show it’s not working right but if it’s not running the thread network is unstable. It’s all really weird.
