I got an ZBT-2 yesterday and migrated my z2m network to it. No problems there.
Then I reconfigured my old ZBT-1 to use thread and I have a HA OpenThread Border Router showing up under Other Networks in the Thread Preferred Network configuration. The Google Nest Hub is set as the Preferred Network. But I can't set the HA OBTR as preferred network. I tried "send credentials to Home Assistant" and "Sync Thread Credentials" in the Companion App > Troubleshooting section. I will deliver any additional information...

ZBT-1 OTBR: Can't establish preferred network

Man, I’m hoping someone can help as I’m pulling my hair out… I am trying to set up a new ZBT-1 as an OTBR in Home Assistant. I followed the instructions here for a new Connect ZBT-1. The process appears to have partially succeeded, in that OpenThread has been installed, and I have an OpenThread-based border router. HOWEVER, I don’t ha...

#

The Nest hub will be retired now...

#

Thank you!

#

The HA OTBR is used now, but how do I remove the Nest Hub?
