The graphs allow you to look at stored data as well as real time (1 sec) data.
The project is on git hub at https://github.com/lelazary/elma
There are only two source files to look at,
the perl program: https://github.com/lelazary/elma/blob/m ... adMeter.pl that reads and parses the meter data (saves the output into a json and rrd)
the web graphing program: https://github.com/lelazary/elma/blob/m ... /index.php
I plane on creating some advance features to identify and label major appliances, as well as generate alerts for abnormal behavior (water leak, unusual power usage, etc.).
