Mosquitto Add-on with diffrent mqtt port

[Kuesel]

Hi all,
!'m currently testing a switch from ioBroker to Home Assistant. My first step is to integrate my Shelly switches, which I control via MQTT, into Home Assistant. To do this, I’ve installed and configured the Mosquitto add-on. As a special note, I’ve used port 1882 instead of the standard port. This setup has worked seamlessly in my previous ioBroker installation. However, in the MQTT integration of Home Assistant, I don’t see a single Shelly device.

While troubleshooting, I noticed that the configuration of the port in Mosquitto doesn’t seem to take effect. Here’s my configuration:

And here’s an excerpt from the Mosquitto protocol:

It seems to me that Mosquitto is still listening on the default port 1883.

I did not configure a mqtt-user within the add-on. I configured the same user as used by the shelly devices directly in home assistant.

Do you have any tips for me?

Thanks in advance,

First post, first failure. Here is the correct screen from mosquitto config.

Sorry for that.

Did you clik the Save button at the bottom of the add-on config before restarting the addon?

Changing the port is really going to create a lot of work for you. You will also have to change the port in all of your devices and other integrations that use mqtt may not even have the option to change the port.

Hi tom_I,

yes, the configuration was saved and mosquitto has been restarted afterwards.
All my devices are running on port 1882. That’s why I want mosquitto to work with that port.
I changed the port of one of my shellys to 1883, same on mosquitto and the mqtt integration.
I see this in the logs

2024-01-27 11:11:23: New client connected from 192.168.178.61:22958 as shelly1-E09806963789 (p2, c1, k60, u'mqtt').
2024-01-27 11:11:27: New connection from 192.168.178.50:35401 on port 1883.

But in the mqtt integration I still don’t see any device.

Any ideas?

Thanks, Kuesel
