If you have a smart meter this is the cheaper way to go. I have had the Rain Forest Energy monitor for almost two years works great on letting you know energy consumption...real-time and accurate...Cheap too...*$69.00

Quoted from mcluvin:50 amp power inlet is installed. Ended up putting it in the garage as I was going to have to drill the studs above the breaker box otherwise. You really have to measure 6 gauge wire just right to get it to all fit in the box. Gonna do a test run tomorrow as it is about to storm here.
Anybody running a Sense Home Energy Monitor? Kinda pricey, but I like the concept.
