I can write up the sensor setup I have at home, if you want. It has motion, temperature, humidity, light sensors and IR/RF remotes for controlling devices, and a burglar alarm.

I'll write up the details, but this is a good chunk of it.
I'm pretty disheartened, I'll try some more and either succeed or go back to an Arduino over serial... Do you have any experience with making it not crash?
Good luck!
By the way, if you don't want to keep checking the comments, you can follow me on Twitter at @stavros and experience my frustration first-hand. I'll be posting about it there.
