So I have home assistant up to date, and just got my ZBT-2. I set it up as a thread, it updated the firmware, then installed the OpenThread Border Router (All ruining without issue). It installed thread (matter already Installed). Rebooted HA, and now it shows Thread using the preferred network that it created using the OpenThread Border Router.
Now when I try and add a matter/thread device by scanning the qr code (Via phone HA), it starts to connect to the device and after a few seconds it says "Your device requires a Thread Border Router. yet I have it installed and running.
What am I missing?
Found the issue. Posting so other know: On my phone, and in the HA app go to Settings->Companion App->Troubleshooting->Sync Thread credentials. For me the “Send credentials to Home Assistant” button on the Thread integration always failed. Anyway, once I did this I was able to pair this device.
