ZBT-2 frustrations forming a new network

Jelving-hub · November 28, 2025, 5:01pm

I am new to home assistant and felt a good place to start was to incorporate the new ZBT-2 hub for Zigbee. I have tried multiple times to bring this in but get stuck on Forming a new ZigBee Network. I have left it for multiple hours with no luck. I have tried hard booting multiple times HA (using a pi 5), manually flashing firmware to ZBT-2, used a few different usb c cables (one it shipped with was bad). HA is running current firmware with no updates pending. Does anyone have any ideas I haven’t tried, or experiencing the same issues as me? Help!

Same here, zbt-2 Arrived today and I’ve been going crazy to set it up for two hours.
Did you find a solution?

Nothing yet. I have disconnected and removed all radio hubs. I have also restricted my 2.4 wifi to channel 1. I have also ordered and installed 10ft usb 2 cables. Still same result… I will update this thread I figure this out.

I would recommend writing up an issue on this here and see what they say. In my mind, there should be a timer associated with this process, and if it times out, present what caused it.

Same issue here.

It never moves past ‘Forming a new Zigbee network.’

I’ve created an issue.

### The problem I am running Home Assistant via Docker on Ubuntu 24.04. I have …zigbee2mqtt and mosquito containers setup and configured. On the devices and services dashboard, the 'Sonoff Zigbee 3.0 USB Dongle Plus V2' card appears and I can click add and start the setup process. It hangs every time at 'Forming new network' and even when left overnight it never proceeds past this screen. I'm not sure what logs to provide to be helpful but I'm glad to do so. I found others with a similar issue here: https://community.home-assistant.io/t/zbt-2-frustrations-forming-a-new-network/956361/3 ### What version of Home Assistant Core has the issue? core-2025.11.3 ### What was the last working version of Home Assistant Core? _No response_ ### What type of installation are you running?

So after looking at the log I figured out it was an issue with usb connection. I switched to another port on my pi and success. Frustrating, although up and running now
