Zigbee stops working after restart

Configuration Zigbee

Unfortunately I get problems with zigbee2mqtt when I have to stop the addon to get a battery for example. Unfortunately, zigbee will no longer start with the following log:

The only way I found to get it working again is to remove the addon along with Mosquitto and the

folder “/var/lib/homeassistant/homeassistant/zigbee2mqtt”. Unfortunately, I have to reset all the devices.

There must be another way, but how? Hopefully you have a solution?

I don’t understand what this means. What do you mean by “get a battery”?

Everything in that log looks normal right up to here:

Tell us about your hardware and Home Assistant system. Could this be a power issue due to you trying to power too may things on a Raspberry Pi USB port for example?

I have been working on this problem for some time. It was necessary to insert a new battery into a sensor. After that, it all stopped working. Even when the sensor went out of range, it went wrong.

Hardware is a Raspberry PI5 with Bookworm (uptodate)

HA OS: 2025.4.3 running in docker

addon: Mosquito Broker, Zigbee v2.2.1-1

First time I’ve ever heard that happen. Worst case you may need to re-pair the sensor.

Is this using an SD card or SSD?

Is your zigbee adaptor on a USB extension lead?

5

You dont need to stop the addon to replace the battery of a sensor.
Only thing maybe (in some cases) you have to repair the sensor.

6

I thought they were implying that replacing the battery caused z2m to halt. Which I find hard to believe, so maybe you’re right. Maybe they (needlessly) stopped z2m to replace the battery.

7

I use an SSD and a USB extension cable.

8

The SSD and Zigbee dongle maybe drawing too much power. Try a powered USB hub.

Thank you. I used Domoticz with the same hardware and everything just worked there.

Problem solved. I bought a Sonoff 3.0 Plus and everything is working properly now.
