Is there a way to switch light on and off, and even dimming lights with the Beovision 7-40 MKIII. If the answer is yes, how many lightsources can it contro, and can it do it in different rooms through b&o ir-eye? What about curtains and a projectorscreen that can go up and down?

How is it, does it have all the functions that BS3 has?

No, not for now, but it only needs a softwareupgrade, so hopefully in the near future..
