In zwave-js-ui i See mij usb device and qubino modules.
How can we connect to Domoticz

I tried so much but MQTT gives:
2023-03-22 10:13:15.177 INFO MQTT: MQTT client reconnecting
2023-03-22 10:13:15.181 ERROR MQTT: Mqtt client error connect ECONNREFUSED 127.0.0.1:1883
Error: connect ECONNREFUSED 127.0.0.1:1883
at TCPConnectWrap.afterConnect [as oncomplete] (node:net16)
2023-03-22 10:13:15.183 INFO MQTT: MQTT client closed

We have made a setup in zwave-js-ui for MQTT
localhost port:1883 prefix zwave

We also made a setup for home assistant. Prefix domoticz
Do We need that for Domoticz?

MQTT auto discover in hardware from Domoticz
Discover domoticz

How can we solve the problem?

Well the error is:

ERROR MQTT: Mqtt client error connect ECONNREFUSED 127.0.0.1:1883

So it is a connection issue

Can you connect to it with MQTT Explorer?

No. We use MQTT with lan interface in Domoticz
There we have localhost port 1883. We need that for Node-Red. That works well.
We can not connect to it with MQTT Explorer. Not with 127.0.0.1
and not with raspberry_ip_adres.

We have also tried with MQTT discover in Domoticz., need for zwave-js-ui on the same port.
