I mentioned Wattvision previously, and the company is now running a Kickstarter campaign to deploy its complete the next generation of hardware, cover more types of power meters, and deploy the new hardware by about January 2013. Wattvision 2 includes a sensor that attaches to your home electricity meter and a gateway that connects up with your internet network. With these in place, a user can check electricity use online or from a smart phone.
A new company, Wattvision, is rolling out a beta version of an energy monitoring system, and it seems promising. The company is selling the Wattvision Sensor for $199 (currently only $149 with the code “wvbetablog“), which can be applied to compatible digital meters. With an online account at Wattvision and the sensor installed, you can start monitoring electricity usage online, on your phone, or through email reports.
