My Zigbee2Mqtt seems broken

Garfield2108 · November 10, 2025, 11:40am

Hy All,
this is my first topic here and I checked the forum but din’t fiind any simmilar issues.

My Zigbee2MQTT is runnign since a few years.
Now for any reasons, my devices can’t be controlled anymore.
I always get an error in the logs

[2025-11-10 12:37:43] error: z2m: Publish ‘set’ ‘state’ to ‘Wohnzimmer_Schalter_1’ failed: 'Error: ZCL command 0x54ef441000bdd7c2/2 genOnOff.on({},

When I restart Zigbee2mqtt addon the system is running for a few minutes and then the issue starts again.

I have no clue what happend, I only added one new client device but din’t change anything else.

I use:
Homeassistant 2025.11.1
Zigbee2MQTT: 2.6.3-1
Sonoff Stick P

Any idea?

problem

### What happened? Devices are lagging and not properly communicating with the …coordinator and Zigbee2MQTT. Similar to closed issue 22189. In relation to the SLZB-06, I have flashed the Zigbee firmware from 20230507 forward and would get the errors within an hour. Kept core firmware at v2.5.6. Mains devices in particular randomly drop and come back after a short time. This did not happen previously. Tried uninstalling and reinstalling Zigbee2MQTT as well to no avail. ### What did you expect to happen? Devices to communicate and work in a timely manner. ### How to reproduce it (minimal and precise) The error does not seem to be consistent, other than as devices send information to or from the mains or endpoint devices I get the error. There are also delays on the communication between the devices up to a minute. ### Zigbee2MQTT version 1.40.2-1 ### Adapter firmware version 20240710 ### Adapter SLZB-06 ### Setup HAOS 2024.10.2 Sup 2024.10.2 OS 13.2 FE 20241002.3 ### Debug log [2024-10-16 11:41:22] error: z2m: Failed to read state of 'Deep Freezer Plug' after reconnect (ZCL command 0x70b3d52b6001ba61/1 genOnOff.read(["onOff"], {"timeout":10000,"disableResponse":false,"disableRecovery":false,"disableDefaultResponse":true,"direction":0,"reservedBits":0,"writeUndiv":false}) failed (Timeout -

What device did you add ?

Garfield2108 · November 10, 2025, 3:41pm

I just added a Sonoff Actor to my lamp.
and changed the battery in some devices thats all.

At the moment it is running after a restart.

Maybe the stick has an issue, I will try to check the firmware and maybe get a new one.
Is the Sonoff Stick E still the best one for Zigbee2MQTT?

A WIFI might have changed channel and now you are interfered with.
Do you have an extension cable on that donble to get it away from all other radios?

More things to look at here. Just because your RF system worked yesterday, doesn’t mean it will work today and it’s usually NOT hardware.

If these are zigbee 1 devices (not zigbee 3) they may need to be re-paired.
