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

HAVOC system monitoring.

Monitoring of a solar installation with 24V 330W panel, Tracer4210AN MPPT controller, 12V 138Ah battery and 12V 1000W inverter. Used STM32F103 to decode controller data and get inverter current and SIM808 GPRS module to communicate with ThingSpeak
