Reasonable preset of MQTT topics

[Phi2k]

After I moved my installation to docker containers I almost gave up because I did not get it working. Reason for the system not working was wrong strings in the MQTT. After installation lots of settings like e.g. speed come with "(null)". If you do not change these to the expected values the server will not accept any changes from MQTT at all.

Is it possible to directly set all MQTT topics to a working preset?

This is a setting which works for me. Make sure you setup every fan. Even if not installed.
You have to stop the server in order to make the changes if you have a malign setting.
The MQTT Broker must be setup in a way that all states are updated after the server is connecting.

The JSON-File at "state" must also be set accordingly and must not be contradicting the other settings.
