My setup:
Gigabyte GB-BMCE-5105, running HAOS natively.
- Core: 2025.3.4
- Supervisor: 2025.03.3
- Operating System: 15.0
- Frontend: 20250306.0
Running Zigbee2MQTT over a Sonoff USB dongle (USB0)
So far so good. Now I wanted to try out the Thread functionality. So I purchased the ZBT-1.
But I failed to configure it and now I am really clueless.
Plugged it in (with extension cable) to the USB1 port.
Checked Settings/Hardware and the new stick was identified.
![zbt-5]()
Went to Devices&Services.
Under the Discovered section, I could find Home Assistant Connect ZBT-1
Clicked the Add button and selected Thread as firmware.
Then it tried to install/configure the OpenThread Border Router add-on.
After awhile it errored out with the same message as in this thread:
Configure ZBT-1 is not possible
The OpenThreadRouter log says:
