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.

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

Currently, this Nodemcu is used to measure the capacity from recycled 18650 notebook batteries. Values maybe empty before new battery start.

Contains necessary variables and fields for lamp two. Collects data on street lights to analyse the street lamp environment and make meaning from it .
