I want more info, now! ;-)
If this is in the right price range it feels like the solution for a lot of installs! This looks like a perfect "not light technician solution" to stick in the hands of SM, Sound tecs and so on to just turn on some parts of the rig. and the hall lights.
Please release more info sooooon!
