Hi. I have one IKEA Thread Border Router (DIRIGERA) as my only physical TBR in my mesh (9 other Thread mesh devices, no other Thread adapters). I've just looked at my Thread mesh network diagram in HA for the first time (I discovered it under Matter Server menu --> Thread tab). It shows the IKEA TBR as "Unknown Device" with type: "Router (external)". Down at the bottom, I see a message:
This device appears in Thread neighbor tables
but is not commissioned to this fabric. It may be
a Thread Border Router or a device from another
Matter ecosystem.
How can I commission my IKEA TBR so that HA's Matter Server accepts it into its fabric properly?
I suppose DIRIGERA is also running its own matter server internally too. Not sure if that complicates things or not.
