CSE7766 ESP8266 Arduino library and firmware https://github.com/vanvuongngo/CSE7766.git fork of https://github.com/ingeniuske/CSE7766.git
Created stand alone library for the Sonoff Pow R2 power switch with energy monitor witch uses the CSE7759/ CSE7766 as power monitor sensor. Based upon the excelent espurna platform of Xose Pérez "Home automation firmware for ESP8266-based devices"
https://github.com/xoseperez/espurna/blob/dev/code/espurna/sensors/CSE7766Sensor.h
The serial port ground from the Sonoff device is directly connected to AC-mains.
Be carefull it could potentially destroy your devices if connected directly!
