I wasn't too happy with the granularity of the Pachube solution and the lack of data access made me look for a better solution.
So I started with setting up a couple of tables on my MySQL webserver. Added a REST interface to it and implemented the corresponding code to my datalogger on my Edimax OpenWRT machine.
Finally I implemented the pGraph library from SourceForge and provided some basic graphs for daily use :
- Solar Production
- Solar Efficiency
- Solar Production Today vs Yesterday
- Power Consumption (last 24h)
- Power Consumption (Day/Night per day)
- Solar Production vs Power Consumption
