I haven't developed an app on iOS before, so this might not be possible.
I am using HomeWave and liking it! I have been thinking about wall-mounting an iPod Touch, and running HomeWave on that.
Does iOS allow an app (when running) to turn the screen on and off? I was wondering if HomeWave could watch a device (virtual switch) and use that as a "screen on/off" signal. I'd love to be able to turn the screen off during movies, when away, overnight, on vacation. It could turn off when it sees the switch go off, and turn back on when the switch is turned back on. Then I could use Vera scenes to control the switch to meet my needs.
I was hoping to be able to turn the screen completely off, but if that's not possible, maybe just the backlight?
