TSalwach @ github.com build a 3-phase home power meter system. A STM32F072RB MCU on Nucleo evaluation board make measurements and Raspberry Pi 1 collects data and share via web interface.
I want to have real time power measurement of my home in my smartphone. I’ve got one some long time ago, it was counting time between pulses on energy meter. It was sufficient, but when I upgraded my home to three phase AC I thought it would be nice to have some new gadget, so I’ve built one.
