Belkin WeMo Switch + Motion Sensor
$129 (usual price $159)
Belkin's WeMo Switch + Motion Sensor kit can help you save on your electricity bills, especially if you tend to forget to switch things off.
The Wi-Fi-enabled WeMo Switch uses a smartphone app (Android and iOS) to switch your home appliances and electronics on and off, as long as you are connected to the Internet.
The Motion Sensor plugs into an electical outlet and detects motion up to 3m away. It then sends a wireless signal to the WeMo Switch to turn the connected device either on or off.
