I have a Current Cost box monitoring my power usage at home, with a bit of perl and with the help of a MQTT message broker, I’ve got the data being reported to Google Power Meter (Broken link
http://www.google.com/powermeter), and to some RRD files locally. The graphs below are being generated from them.
I’ll try and tidy up my perl a bit and put some more stuff here in the future, until then here are some mostly pointless graphs 🙂
