So far, convincing (update follows)

My Config: FS 20 LES, 4x FS20 radio switch, instead of the S300TH I chose the slightly more expensive ASH2200, S300 grad was not available and ASH2200 is somewhat high, plus 2x fan Eco-Matic 150mm. I want to control 2 fans and 2 dehumidifiers.

I have not yet built anything and therefore can not say anything yet from the actual live environment. But it's all connected and set up and works just fine and intuitive! By addressing system you have to deal with a couple of minutes then klappts 1A. In dry operation everything is perfectly controlled and measured, am curious how it is then live.

A so ingenious, practical and expandable control at the price was really surprising to me. After much research I Google previously encountered only finished systems that would cost 1500-2500 euros in my config.

To be continued ...
