Update: Maplin have discontinued the electricity monitor used here (N94KQ) and Maplin don't even exist now.

I've added a basic Python 3 version (N94KQ-basic-python3-console-logger.py) that outputs to the console (if you setPYTHONUNBUFFERED=true).

There is also a Python 3 port of the original version (thanks to Dave Cutliffe).

Software for monitoring the electricity consumption of a home with a Raspberry Pi (or other Linux machine) and a Maplin electricity monitor (N94KQ).

Copy thewww folder to/var for httpd to host and the python file to anywhere.Installpyserial withapt and plug in the receiver.

To run executesudo python raspberry-pi-electricity-monitor.py & or add this to/etc/rc.local to run at boot.Visit your pi in a browser to see the data.

I've added a new script (maplin2emoncms.py) which you can use to push the data toOpenEnergyMonitoremoncms running on the Pi.
