iPhone Screenshots


PowerMeter App turns your device into a Wattmeter. Just point the camera at the red flashing light on your electricity meter and get the reading!

Using PowerMeter you can measure the standby power of devices at home or electricity production of your Solar PV panels.

The App measures the time between impulses ±20ms and calculates the corresponding power usage with high accuracy. Depending on the class of your electricity meter the result is ±1% or ±2% whereas popular energy monitors are sometimes even 10% off.

Used by professionals, many 5 and 4 star reviews!

• "Nice app - works perfectly. Congratulations!" – Lavello, Italy
• "Excellent - Excellent thanks for your effort!" – Solar narsti, Australia
• "Superb App to know your consumption instantaneously. Recommended!" – Pascal, Switzerland
Note: This App will not work with infrared LED, so if you can't see a red light flashing on the meter the camera will not be able to detect the impulse.

What’s New

Version 3.1.0

Nice easy to use little app

Nice little app that does what it says. Simple to use. Would be great if it averaged the kW usage over the period you interogated the meter and kept that average in a table for future reference and comparisons.
