MQTT and Zwave-JS-UI problems connection to Domoticz

[skevik1]

I got an unwanted surprise when the support for OpenZwave disappeared in the new Domoticz release.

Therefore, I had to follow the instructions on how to setup zwave2mqtt and so far all the devices are visible in ZWaveJS-UI and parameters in Domoticz hardware settings are corresponding to the settings there.
I also installed the MQTT broker.
However, no devices are coming into and are visible in Domoticz hardware settings.
I suspect that Domoticz cannot pick up the devices as it should, I suppose.
Does anyone knows how to come further?

I'm running Domoticz directly on a Ubuntu Linux and have installed the MQTT broker. ZWaveJS-UI is running in Docker on the same machine. I have posted the logs from ZWaveJS-UI if this may help.

My mosquitto conf file has

listener 1883
allow_anonymous true

Are you sure you used the correct ip in the Zwave JS UI uner Settings MQTT? Use the ip of the server you have the MQTT broker running.

That's correct, don't use 127.0.0.1 or localhost, use the IP address (like 192.168.0.10)
