Powe rMeter Web App from Google
Slash your electricity bills and find the power-hogging beasts that inflate your electricity bills. You can now use an app from Google to track how much electricity you consume in your home and you can do this from your PC or your phone. All you need is Wi-Fi, Internet access via broadband and of course, Google's PowerMeter app.
Blue Line Innovations had linked up its PowerCost Monitor to the PowerMeter so that you can keep an eye on your electricity usage. You get an energy display, an electricity meter sensor as well as the Wi-Fi Gateway. The Gateway allows you to see data from your meter on the Web, get real-time information about how your energy is being used, predict your costs and also share energy saving tips with other people.
