Solar Power Monitoring, well that and most of the other energy consumption in a typical house. Mostly I was interested in how my 1900 Watts of solar panels was working.

Energy monitoring using NodeMCU-ESP8266 with SCT-013-000 - 100A, non - invasive sensor. Monitoring phase 1 of my house.

The video (not mine!) explains the settings of a similar system I am using. For more info, go to http://openenergymonitor.org/emon/ Other sites where I publish live data: http://daturach.github.io/ http://emoncms.org/daturach
