Thanks for the input!
Maybe a 'shut off the lights every 30 minutes' type macro or something.......or maybe I'll kick off a macro whenever I detect motion (there's an MS10a in the room) that turns off the foyer light 10 minutes after someone walks through....I'll have to play around and see what works best.
My wife stays home during the day so the lights are often left on for long periods of time. Are there any wall switches that do send x10 codes when activated locally? I googled it up but didn't find much info one way or the other.
On another note, have you guys seen
http://www.thex10shop.com? This guy is selling the stuff for cheaper than I can find it on x10.com and/or ebay. And his shipping is ridiculously reasonable too. Maybe it's old news, but just wanted people to know.
