Moved from RaspPi to GMKTec Mini PC - Zigbee2MQtt not starting

stephang · July 19, 2026, 9:29am

Hi Team,

I restored a back up of Raspberry Pi to new hardware today.

I did try to change the name of the device in from the hardware finding the by-id lince in the hardware, but still fails.

Zigbee2MQtt gives me errors and won’t start. Any ideas

Hi Stephan, what do mean by

Did you or did you not and have you checked that the port is the right one.

How are you running Z2M, what kind of HA setup do use?

stephang · July 19, 2026, 10:22am

I am not sure what you mean by check port?

How do I do that

Nick4 · July 19, 2026, 10:24am

What about

stephang · July 19, 2026, 10:25am

yes running Z2M and running HA = Home Assistant OS

But I can not get Z2M to start

Nick4 · July 19, 2026, 10:31am

Under configuration → Serial: is that correct?
Compare with

stephang · July 19, 2026, 10:34am

I took the first line

Then

But this is still generates the same message.

Dongle is ZBDongle-P

Nick4 · July 19, 2026, 10:37am

what if you put /dev/ttyUSB0 in serial → port

stephang · July 19, 2026, 10:38am

Nick4 · July 19, 2026, 10:41am

Did you check if it’s the right port

on your new system?

stephang · July 19, 2026, 10:44am

this is all on my new system.

stephang · July 19, 2026, 10:52am

I tried a few more times and it seams to have resolved itself, but I am not sure what it was that fixed it.

Nick4 · July 19, 2026, 10:54am

What did you try so that it resolved by itself?

stephang · July 19, 2026, 10:58am

The only big thing I tried was in devices pres “Add Zigbee Controler” it then went to a spinning wheel. But after trying that the Z2M started and is running now. It still spins. But 99% of my automations have started to work again from motion etc

Nick4 · July 19, 2026, 11:02am

What is that screenshot?

Are you using ZHA as well as Z2M?!?

stephang · July 19, 2026, 11:03am

when you go to settings there is now a ZIGBEE item in the menu next to THREAD etc

But I am using Z2M not ZHA

Nick4 · July 19, 2026, 11:05am

Are you talking about

stephang · July 19, 2026, 11:07am

stephang · July 19, 2026, 11:07am

After pressing this from DEVICE page.

Nick4 · July 19, 2026, 11:08am

That is ZHA imho.

Check

There you go: that’s the reason why your Z2M is not working.
You can’t have both with the same coordinator!
