Additional context

Would be nice to have MQTT mini-server disabled by default, and enable it only when necessary in rodere to limit necessary resources.

TThe built-in MTT server is not a full MQTT server and does not affect the performance if not used. This was just a test and we will add configuration to enable it etc. I also looking to use the integrated MQTT part of HA.

Then that is the reason. You can downgrade one instance to b1 for now.

Yes will add settings like that with default to off. I just want to see if it working for others than me first.

Can you change title to some thing like; Add settings for mqtt?
