Help for setting up MQTT via home assistant add-on needed

kingisch · January 3, 2025, 2:22pm

I am having trouble setting up mqtt via the add-on.

Here is what I have done:

I added mosquitto broker as an add-on (no changes in the config)
I created a new person in people with the name mqtt and a password
I then restarted home assistant - weirdly I already get a couple of requests in the Mosquitto logs (see below)
now MQTT is automatically detected, so I click on “add”
I reconfigure it with the new User and Passwort but get the following error:

So now I am puzzled… Where do the mosquitto broker request come from? Is the mosquitto add-on as well as the MQTT integration set-up correctly?

Here are the logs in the broker:

Any help is appreciated. Thanks!

Hi OIaf,

This has always been flaky for me.
I just use the configuration screen in the add-on to add a user and password.
If you want it hidden, use !secrets.
If you want to use secrets add then first, then restart HA so they get into memory, then add them to the addon.

Thank you for your answer @Sir_Goodenough,

That helped indeed. I have also googled some more as I was wondering why there were so many frequent and unknown MQTT calls. Here is the answer:

github.com/home-assistant/core

Unknown client connecting to MQTT broker

TLDR: the unknown MQTT calls are normal and cannot be stopped
