Hi trygve,
Did you ever do the writeup of your setup with the Velux KLF 200 and z-wave devices?
I'm looking at doing the same for my 4 Velux windows and blinds - I can see the KLF 200 with allow external controls but it's not clear what type of z wave device (e.g. relay/blind controller).
It would be really helpful to get more info please.
