Energy gateway gadget
The sensor on the meter attaches to this small gateway inside and the gateway uses Wi-Fi and a home broadband connection to send meter data online. Then you set up an account online and you can view a data graph of power in real time, by day, or by month. Looking at spikes in the data graph makes you curious about what causes them. Seeing power usage overnight gives you a good idea of a house's "baseline," or always-on, electricity use. The idea is that using that information--and in the future, more analysis on that data--people can get ideas on how to save energy and avoid being surprised by monthly power bills.
