Current Cost energy monitor in my flat.

Reading is the current electricity consumption in Watts.

Using an Arduino with Lady Ada ethernet shield + Wiznet module.

There are some rogue values creeping in here, which I presume are my fault (i.e. the arduino's). Need to do some further investigation.
