I have a SLZB-MR1U set up in thread mode, which HA is controlling via the OTBR Add-on. If I understand correctly the actual OTBR software runs in HA and the SLZB-MR1U is just acting as the radio(etc).
I have a ZBT-2 I got as a backup. It’s installed on a Raspberry Pi running ubuntu where I did a native (source) install of OTBR. I added it via the rest API to HA.
When I look in HA I see one preferred network and both devices.
If I access their web interface, it looks ALMOST like what I expect. The HA one shows the first topology below. Note it shows both a leader (itself) and router (the ZBT-2).
The second toplogy is from the ZBT2 one (or more precisely the OTBR software on that rPi). Notice it sees both but there is no “leader” shown.
Should it show the other as the leader? It correctly identifies where they are connected. I just don’t know if the “leader” aspect is important?
