Back in March I bought an "E-On" branded Current Cost Energy Meter on EBay for £32.00 GBP including surface mail (NZD$82). Yesterday it arrived. [You can buy them in New Zealand for $150, $200 or $239 - which would be much quicker delivery.]
The main benefit of the Current Cost meter is I can monitor my whole household power usage. And I'll be able to produce graphs of usage over time. That will allow me to really understand my power demand, and therefore modify my behavior in ways that actually reduce my energy usage.
I plugged it in today - very simple setup. The transmitter has 2 D sized batteries and lives inside the metal meter box on the outside of the house. I'm impressed that the transmitter works through the steel box.
Currently my based load (things that run all the time is somewhere around 176 Watts.
My "base load" appliances are:
There's plenty of potential to reduce this list.
Next step - make a data cable:

I also looked at buying a Centameter - which is wireless - but has no data port. I could have built my own wireless receiver for it and work from that - but that seems like more effort than I can be bothered with.
