Home Assistant ZBT-1 Thread Device goes offline after reboot

Hi all, I’m experiencing this problem where if I shut down or reboot Home Assistant (running on a Pi 5 8G), the Open thread border router will be offline when it boots back up. A quick trip to settings, system, hardware then click configure on the ZBT-1 section, resolved the hardware issue, then I can go back into the border router, click reload and all is back to normal. This appears to be 100% repeatable. I haven’t noted anyone else with this issue, so am asking here. Has anyone seen this before and is there an obvious fix? Otherwise this all works well with the Nanoleaf bulbs. Thanks.

Hi Marshall,

Quick thought on my part, you are using the extension or even a longer one to get the dongle away from the electronics in the PI. They will do strange and terrible things to your dongle radios if close together. The extension comes along for a reason.

Thanks. I do have it on the extension yes. I don’t think that that would require a reconfigure of the hardware at boot each time though right? I actually think it’s just trying to re-write the firmware each time at boot and it doesn’t do it. So I go in and do it manually and then it works. Does anyone else have one of these that they can confirm survives a reboot? Being it’s the official device I would have thought there was a lot of people using them and they’d be a first class HA citizen. That’s why I bought it.

And if they do have one of these, that then points to my configuration I guess. We had a power cut last night. I had to shut it down. Upon reboot, you guessed it, has to be reconfigured again.

Im having the same issue with a proxmox vm running HAOS

I think this actually was fixed in the latest upgrade, at least it started working. But then the Thread Border Router got an update and it’s broken again. Might be inconclusive but I did test two full reboots after the upgrade but before the thread border router update and it recovered both times perfectly. Now after the TBR update it’s back to needing the hardware reconfigured at each boot again.

i’m having the same issue.

I have the same issue, the problem seems to be ZBT-1 dongle not being automatically configured as Thread for me… everytime HA restarts I need to go into settings and manually configure ZBT-1 to thread and reload the thread integration and everything comes back to life.

haven’t found anything useful yet to solve the problem

I don’t know if it’s solved it yet, but I did discover a setting in settings, add ons, open thread border router that says start on boot and it was off. I assume it was meant to be on, so I have enabled it. That may kick something off I don’t know. Of course I also checked the matter server as well which was already on. Also enabled watchdog as it seemed sensible.

Cross-linking to another thread where myself and several other users are seeing Thread issues with SmartWings blinds. I was able to resolve my issue by rebooting the Matter Server Add-On in Home Assistant.
