For my new home I plan to implement some decentral controlled domestic ventilation (in german kontrollierte, dezentrale Wohnraumlüftung). My favorite device for this is the Siegenia Aeromat VT WRG 1100.
It could be controlled via Siegenia Sensoair (which is a zWave enabled device, but not really stylish) or via wires.
I agree - unless you can put it under one roof like OH and everything is automated.
My main idea is, if there is WIFI available on it I can access it by a web interface and intgrate it into OH.
Zwave would be even better for me, but placing the WRT 1000 will not work.
I need the tube ones.
