All the goodies...
TV's, coffee makers, powerbars, you name it... anything that you simply want to power on or off.
Lights can be turned on/off or dimmed to any level. Make sure that lights are off when you're not home, or set the mood when watching a movie.
Organize devices into groups however you want (e.g. Kitchen, Lighting, etc.) so that you can find them faster.
Create custom actions that do whatever you want - whenever you want. Turn off a bunch of lights with one click or even on a set schedule.
