oekofen-stats

Simple scripts to fetch statistics from a ÖkoFEN Pellematic Smart solar pellet heating connected to our LAN.

We want to process the log generated by the ÖkoFEN heating controller and produce nice graphs.

Requirements

This requires perl as well as rrdtool.

Components

The fetch-log.pl fetches one log file at a time and calls process-log.pl with the retrieved file name.
process-log.pl iterates through the log file and stores the interesting values in RRD files and creates some graphs.

Install

To install, copy the whole lot to /usr/local/oekofen-stats/ and

Copy oekofen.cfg.dist to oekofen.cfg
Edit oekofen.cfg to change the correct URL of your Pellematic smart
Configure your webserver to serve /usr/local/oekofen-stats/web/
If you are happy with the result, install the cron job in order to fetch new values every 5 minutes: ln -s /usr/local/oekofen-stats/cron/local-oekofen-stats /etc/cron.d/
