For some time I’ve been monitoring my home’s aggregate power consumption using a CurrentCost EnviR.  I’m now planning to upgrade my monitoring hardware.  Firstly, I want to install CurrentCost Individual Appliance Monitor plugs on my appliances (£13.33 each).  Secondly, I want to measure aggregate real, reactive power and voltage using an Open Energy Montitor.

Update 21/6/2012

I bought 3 CurrentCost Individual Appliance Monitors to test.  They seeem to work well.  My main concern was that the wireless range would be too short to allow me to monitor every appliance in my house but the wireless range seems fine.  Sure, the system drops a few more samples from the wireless monitor that’s furthest from the CurrentCost EnviR but the data is entirely usable.  I’ve modified my Python logging script to handle multiple sensors.
