Beth I've not seen anything at Home Depot that would do that but, if you do a search on "X-10" you'll find some interesting information. My understanding is it's a software app for your PC and it's got a transmitter/card with it that sends out signals to recievers that are controlling your power heads, lights etc. So you can use it as a wave maker/light timer/ auto feeder etc etc... Some people on this board have had problems with them though.
