I made this module as a bolt on (shield) to RPI B+
Dont know how to edit this wiki so , bare with me before I get this under control.
I logged my energy before via an optical sensor to the meter supplied by the power company , but wanted to see this now on a phase level, thats why i developed this. The Optical senor giving Kwh aggregated will be kept for calibration and aggregated power. I logg every minute to an mysql server and via another progarm I can draw curves for any period of time I have collected data for. This includes also a lot of other parameters like temperature etc.
Its using the Analog Devices ADE7878A for Polyphase Multifunction Energy Metering.
