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.

Please do write about it. Personally, I'll be happy to steal as many ideas as I can for my upcoming home installation :).
