What are your thoughts on MQTT setups?

Configuration
1

Hello everyone,

I am getting more and more into using MQTT for things outside of HA. So far I have been using MQTT server/broker on HA.
But I was wondering what your thoughts are on running MQTT brokers on other devices that do not require frequent restarts (HA needs restarting regularly which interrupts MQTT).

Is there really a big advantage of running one that is “always” available? So e.g. if it runs on the router, then it is always available when the network is available.
Or will it not have any real benefits?

Or is there even any benefit to having multiple brokers in one network?

Thank you for your thoughts and ideas.
Alex

This is the issue

I only restart often upgrade. You have hardware or install issue that needs to be resolved

One broker is enough

?

If you’re running the Mosquitto MQTT Broker Add-on, it runs in a separate docker container from Home Assistant. Restarting Home Assistant doesn’t interrupt the Add-on. Rebooting the host machine will, of course, interrupt everything.

As for the need to restart Home Assistant, I rarely need to do that except for version upgrades or installing integrations that are configured exclusively via YAML and don’t have a Reload service.

I am running supervised. If I am not mistaken, that restarts the broker then.

Restarts of course mainly for updates, new integrations etc.
Or when I try out new scripts etc.

I’m pretty sure you are mistaken.
