Wattvision, the newest Plug-N-Play Real Time Energy Monitoring Tool
Wattvision, a new plug-n-play tool for real time energy monitoring allows you to snap a sensor on to your electricity meter and get real-time energy consumption data on your computer or smart phone. Features include super simple displays and social networking tools for energy consumption data. Wattvision, still in beta mode, is selling the Wattvision Sensor for $199 (currently only $149 with the code "wvbetablog"). Once beta mode is over, Wattvision will have a tiered pricing structure based on the level of service a user wants, how much information you have access to and how many properties are included in the account.
If you're interested in how Wattvision looks, you can check out their live demo of a house in New Jersey, which shows energy consumption updated every 10 seconds.
