Zigbee2mqtt not starting up anymore


I’ve been running zigbee2mqtt with a zbmini for about 3 months now and this morning it stopped working.
None of my zigbee device would respond anymore so I restarted the plugin and here is what I get into the log:

> [email protected] start
> node index.js

Any Idea about how to fix that?


Stop zigbee2mqtt, disconnect your adapter (remove from usb), reconnect your adapter, start zigbee2mqtt.
This works for me.

Thanks for the feedback
this didn’t make the trick since I am using a sonoff bridge
However, I solved it by issueing again the following command to map the zigbee chip to the TCP server:

backlog rule1 on system#boot do TCPStart 8888 endon ; rule1 1 ;* *template {"NAME":"Sonoff ZHABridge","GPIO":[56,208,0,209,59,58,0,0,0,0,0,0,17],"FLAG":0,"BASE":18} ; module 0


Solved my problem also. Thank you for that!
How did you find this solution?

Solved my issue as well. Thanks

I went throughh the installation process of the sonos gateway and, by connecting the dots, figured out that this might be the issue.

I also have a sonoff bridge but i’m new to this world… How did you do that? Where and how did you set it up. I have had my sonoff bridge running (and working with ZHA) but i updatet the firmware to Tasmota 10.0.0 and now try to get it to work with Zigbee2mqtt. Please help :slight_smile:


You can follow this great tuto:

Dou you use ZHA or Z2M?

Because I have the same problem that you but I use the Zigbee to Mqtt and your solution is used for what integration ZHA or Z2M?


I completely dropped Z2M. Had too many issues with it.
Moved to ZHA. 100% happy with it!

Ok, thanks
