Customer Questions & Answers

More sensors/Screen readout will show???

if you add more sensors as its suggesting you can do, lets say a total of 4 sensors - will you have the ability to calculate or see what each sensor area is consuming - otherwise whats the use in additional sensors?? just go back to panel box, and meter the circutes that are being used
Asked by: Bosco
Yes, it is possible to see what each sensor area is consuming as well as the total consumption for all sensor areas. You can switch the display between the various added sensors. After you have gone through all the individual sensors, the sum of all sensors is shown.

how much is an extra sensor?

The kill-a-watt item includes one sensor.
