If you can unscrew a face plate, then you can install this timer which simply screws into the bottom hole of your standard wall-mounted light switch. As you can see in the product shot it sits over the actual switch and will physically flick it on or off at preset times and intervals, perfect for conserving electricity or making it appear as if someone is home while you’re not. And while no wiring or electrical skills are needed, a basic grasp of alarm clock programming is required to setup when the device does its thing. There’s also a manual override that lets you turn the switch on or off regardless of the time, and since it doesn’t tap into your home’s electrical wiring in any way, you’ll also need to occasionally swap out a set of AA batteries to keep it running. $39.95 from Hammacher Schlemmer.
