The elite classic is our latest and renewed version of our elite wireless power monitor updates every 10 seconds so you can instantly see the impact of turning a light on or off, using the stove top burner, or your electric clothes dryer. It has an innovative memory function that allows you to see how much you have used today, yesterday and in the last week or month. The elite monitor also displays your daily average so you can see when you are using more electricity than normal and see how your average usage reduces as you change the way you do things.
The efergy elite electricity monitor is simple to install and use. The sensor wirelessly sends information about the amount of electricity you are using to the display monitor. The monitor converts this into kilowatt-hours, the standard unit which the electricity company uses to charge you. This shows how much you are using in the same units that are on your bill. Input the amount your energy company charges you for each kilowatt-hour and you can see how much you are spending in electricity instantly. Make instant changes to save money, energy and the environment.

For most homeowners this is an incredibly useful system for measuring electricity use, especially for appliances that you can't test with a simple plug-in meter like a Kill-a-watt (either because they're hard-wired or because they use 240 V). I used it to quickly track down "phantom" appliances that draw power even when they're turned off, including hard-wired smoke detectors.
Just two caveats:
(1) Installation can be tricky and is not for the faint of heart. In my case there wasn't enough space around one of the feed wires in the panel, so I had to turn the power off and then pull and bend the stiff wires until the sensor finally fit (barely).
(2) If you have a grid-connected solar PV system you should get the True Power Meter instead of the Elite Classic, because your inverters may confuse the Classic to think they're drawing power when they're not (e.g., at night). This is because inverters have a nontrivial "power factor". (Also, of course, the Elite won't tell you the direction in which the power is going between your home and the grid. I don't know whether the True Power Meter can do that.)
We set these up with our geothermal customers so they can decipher their electric bills and see how much it costs for them to heat their home. Straight forward setup.
