- navigate back to scan view and point the camera to the blinking light in front of the energy meter.
- hold the phone in upright position.

App insists phone has to be vertical even though it can see the single led fine horizontally it refuses to try and read if phone is not held vertical and since the phone wont fit in the space vertically this app is useless. Why? The orientation of a single flashing light changes nothing!

Fixed at 1000 Imp / kWh. Even after changing setting to 3200, still using 1000 / kWh A similar app which asks for the value before use, works fine but doesn't have the option of calculating cost so shame this app doesn't work properly. Have to manually divide figure by 3.2 (our meter is 3200 Imp / kWh) to get correct reading.

Wildly inaccurate - changing the impulse/kW doesn't change the readout.
