Here’s a neat piece of pre-production technology called MeterPlug. MeterPlug measures electricity consumption by plugging in between any appliance and the AC outlet. The smart plug uses Bluetooth 4.0 to send data to your smartphone and enable features like proximity control, manual on/off, and vampire power shield. In other words, with a range of about 100 feet and a smartphone, it’s easy to shut down appliances or calculate the costs of standby power. Each plug is a little expensive right now, but if you want to try MeterPlug, you can pledge support at Indiegogo.
