I followed the install procedure. All looks fine in HA. I have openthread running with a preferred thread network of Home Assistant. Matter integration is installed and all looks good in the logs. But when trying to commission a new device, the HA companion app says “Your Device Requires a Thread Border Router”. I note in the “All Hardware” section of HA, I can see “ttyACM0
/dev/serial/by-id/usb-Nabu_Casa_ZBT-2_DCB4D910EF64-if00” but I cannot see any entries for ttyACM1 or ttyACM2. Is this correct?
If you use a mobile phone to commission then you need to sync the Thread credentials to you phone.
You do that in the in the companion app under troubleshooting.
