I have recently gotten a Raspberry Pi, and am looking to use it as a home automation system using the GPIO and Python. Does anyone know any way to link light controls to the GPIO?

One way is to simply rewire the light switches so that when you turn on the GPIO using Python, it closes the circuit. You can do that for a few light switches, but you might want to use several Raspberry Pis.
