Modern power meters require the entry of a PIN using a flashlight. To input the different digits in the form of blinking signals, one must enter them in a kind of Morse code. One blink corresponds to one, two blinks to two, and so on. This can be very tedious and time-consuming, and mistakes can easily happen due to the need for precise timing. FlashMyPin is the solution: Instead of manually inputting individual blinking signals using a flashlight, you only need to type in your PIN and the flash on your phone’s camera blinks in the correct pattern. You simply need to hold your phone in front of the light sensor of your smart meter, and your PIN will be entered in no time. FAST No ads. No registration. FlashMyPin is ready to use right away. SIMPLE With its intuitive interface, FlashMyPin is easy to use. EFFICIENT Instead of laboriously entering individual commands through blinking lights with a flashlight, FlashMyPin saves you a lot of time! CONVENIENT The most common commands are already stored in the app, so you can get started right away.
