zwave-js-ui <---> MQTT broker does not seem to work properly Topic is solved

[kman]

I am in the process migrating from openzwave to zwave-js-ui.

I have followed all the steps mentioned here:
- https://www.domoticz.com/wiki/Zwave-JS-UI
- https://www.domoticz.com/wiki/MQTT#MQTT ... very_Setup

But I was not seeing the devices show up in domoticz.

So, that is when I tried to see if it works fine with MQTT Explorer. From the looks of it, it doesn't look ok. Screen shot of MQTT Explorer shared below:

Please can someone advise what am I doing wrong.

Below I have attached "zwave-js-ui" config details.

The issue was resolved by turning of UFW on the raspberry pi.

> sudo ufw status // if this shows 'active', then disable it.
> sudo ufw disable

To keep it simple, I have been using MQTT from Pi's repos. I am not using docker version for MQTT.

Yes, a firewall could indeed cause connection issues if you have not opened up the firewall for Zwave-JS-UI and/or MQTT mosquitto.
