Problem migrating zigbee2mqtt from version 1.30.2 to 1.41.0

[alkempter]

Hi,

I am using Zigbee2MQTT with the current Domoticzs version and was trying to upgrade my Zigbee2MQTT from Version 1.30.2 to 1.41.0

After that, zigbee2mqtt kept restarting every 6 to 12 seconds without data in the log.

So I started it with docker run and got the output
Error: 'homeassistant.discovery_topic' cannot not be equal to the 'mqtt.base_topic' (got 'domozigbee')

See detailed log:

docker run --name zigbee2mqtt --restart=unless-stopped --device=dev/serial/by-id/usb-Silicon_Labs_Sonoff_Zigbee_3.0_USB_Dongle_Plus_0001-if00-port0:/dev/zigbee -p 8092:8092 -v /home/domopi3i/zigbeemq/data:/app/data -v /run/udev:/run/udev:ro -e TZ=Europe/Vienna koenkk/zigbee2mqtt

Using '/app/data' as data directory
Starting Zigbee2MQTT without watchdog.
[2024-11-13 19:31:39] info: z2m: Logging to console, file (filename: log.log)
Error: 'homeassistant.discovery_topic' cannot not be equal to the 'mqtt.base_topic' (got 'domozigbee')
at new HomeAssistant (/app/lib/extension/homeassistant.ts:470:19)
at new Controller (/app/lib/controller.ts:135:34)
at start (/app/index.js:152:18)

After going back to 1.30.2 the problem was gone.

Autodiscovery prefix is set to: domozigbee
Client Gateway settings are
prefix topic incoming: domozigbee/in
prefix topic outgoing: domozigbee/out

The Domoticz setup contains MQTT settings also for zWave, both are using the same mosquitto installation.

Is there something I have to change in the setup in order to use this new version or is it a bug?

Any help is welcome. Thank you a lot in advance.

Best regards
Al

Finally found a hint in homeassistant community and made the following changes:

in configuration.yaml changed discovery Topic (now domoadzigbee)
homeassistant:
discovery_topic: domoadzigbee

and in Domoticz
Auto Discovery Client Gateway Definition changed Autodiscovery prefix to domoadzigbee

Did not Change in Domoticz Client Gateway the prefix definitions (domozigbee/in and domozigbee/out)

Now zigbee2mqtt starts up nicely and seems to work the same way as before.

Interestingly the zwave MQTT software can live with the same prefixes for auto discovery and gateway definition.
