On these pages you find my experience with X10 home automation.
X10 is the affordable product line for Home Automation. It uses the mains powerlines as communication channel between receivers like lamp modules (dimming lamps) and appliance modules (switched power) and transmitters like minicontrollers or remotes. Most anything that can be controlled by the mains can be controlled with simple X10 devices. The fun starts when computers are added. With adequate X10 hardware and a PC with smart software you can build a smart house that improves comfort and security.
