Energy monitor program for Myron B. Thompson Academy, created in 2014.
In my high school electricity class, we were manually aggregating data from various energy monitor devices in Excel. I volunteered to create a tool to automatically import the data and create interactive charts so the class could focus on analyzing the data instead.
The app supports various filters for the charts, such as only showing working hours. The average energy usage from multiple reports is calculated and displayed with a prominent bold black line.
I extracted some of the parser code and turned it into a more generic library, wemo-chart.
