From the project
Device to view household power consumption
The Internet-of-Things Power Meter (IPM) is a device fixed on top of the regular household power meter and provides detailed information about the electricity usage. Modern power meters have a LED blinking every time a Watt is used, the IPM detects these flashes using a light sensor, counts them and saves the values to an SD card. Later the data is stored on the cloud.

Internet of-Things-Power-Meter: common questions
What microcontroller does the Internet of-Things-Power-Meter use?
The Internet of-Things-Power-Meter is built around the ESP-12, from the ESP8266 family.
How big is the Internet of-Things-Power-Meter PCB?
The Internet of-Things-Power-Meter measures 33 × 61 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Internet of-Things-Power-Meter?
9 components, from 9 distinct parts. The full bill of materials is listed on this page.
Where can I download the Internet of-Things-Power-Meter design files?
From the Nurgak/Internet-of-Things-Power-Meter repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Internet of-Things-Power-Meter design in my own project?
The repository has no license, so all rights stay with Nurgak. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Internet of-Things-Power-Meter without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP8266 firmware against it before you order a PCB.
