counts flashes and rotations, and shows you Watts.
With this Powermeter app, consumers can quickly measure how much electricity is consumed in their home. You can see how much power consumption increases when you turn on the washing machine, coffeemaker or oven. Classic meters have a spinning metal disc. New meters and smart meters use a LED-light as indicator. The rotationspeed and flash frequency depends on the amount of power consumed. The Powermeterapp works like a translator, it displays the current value in Watts and shows a small graph. It works for both model types, DISC and LED. You can also enter rotations or flashes by hand.
