The PowerCost Monitor is a wireless energy monitor that tells you at a glance how much electricity your home is using moment-to-moment and in total. Tests show that households which use real-time feedback reduce electricity use by as much as 5 to 20%. Simply program in your utility's electric rate, and the PowerCost Monitor will display your home's electricity use in dollars and cents as well as in kilowatt hours. Includes two components: A Sensor Unit that attaches to the outside of your electric utility meter, plus a Power Monitor that reads the wireless signal transmitted by the Sensor Unit and displays it for easy viewing. With a range of up to 100ft from the sensor unit, you can place the Power Monitor just about anywhere in your home.Manufacturer Information »
