The best and easiest way is to use the X-10 Power modules, amazing simplicity and reliability and inexpensive. They operate through your home's electrical wire system, so you dont need any wiring or the unreliability of wireless RF units. I think some of the Radio Shack stores still sells the X-10 modules. I have my system rigged up to be even controlled by my cellphone to turn on lights, heat and water my lawn, alarm systems even listen in to the house when I am out. Its been on the market for over 30 years, so its proven, best investment I ever made and the uses grow with the use of your imagination !
You need this plug in controller that serves as both dimmer and on/off remote or you can get a wireless one. This inexpensive module can control and dim up to 8 lights/appliances. They used to have a timer controlled module too so you just set it to turn on or off at a specific time, but I can't seem to locate it now.
