Update: building meters

Just a very quick update. Recent work has been focussed on getting the energy meters ready for the MSc group who will be doing a project on "VIsualisation and Analysis of Domestic Electrical Energy Consumption" next term. Specifically, I've been working to get the Open Energy Monitor EmonTX talking to my rfm_edf_ecomanager Nanode code and discussing ways to eak as much accuracy from the measurement hardware as possible. And trying to find a way to measure reactive power for students who won't be able to measure mains voltage and phase angle directly (this is discussed in depth here).
