Looks great - a bit overwhelming for me :) Hope @pesor will look into this and merge if possible.

I will look into it, I have been following on the sideline, and the input is very interesting.

I did look into the Autodiscover, but then spring and summer happened.

I will really look into everything, when autumn sets in.

I have learned a lot about the sensors this summer, which I will also share then.
