Awesome dead comment: ------- The Wattvision doesn't appear to be anything new. I had a CurrentCost Envi unit (that read with non-intrusive clamps over the leads in the breaker box) that did much the same thing, and would output its data over serial. Tied in with Google Power Meter and so forth. Then, my utility installed the new "Smart Meters", and a few months after that they offered me a countertop unit that talks to the meter using ZigBee and gives me real-time usage information (and historical graphs, etc). For free. Using the data I get from this, along with a Nest smart "learning thermostat" I installed last year, has reduced my "height of summer" electric bills to around $140/month from almost $300/month a few years ago. I've still got the CurrentCost Envi setup, along with "web bridge" unit (Ethernet interface) if anybody in Houston wants one. Trade me a 12-pack of Mt. Dew for it or something...
