[OZAPRS] smart meters ?

[Darryl Smith]

Hi Guys...

I will not make too many comments on the matter as I am now the chief engineer at www.Greenbox-group.com, and if you check out the URL you might find some interesting information. The following comments are personal comments, not related to anything...

Smart Meters have an accuracy of commonly 0.5% or 1%. From what I can see, most of the monitoring devices on the market have sensors that are no better than 2% accurate, with electronics that make things even worse. My guess is that given the AEMO rules for Meters in general, the two will *NOT* line up. And it will be the Smart Meter that is correct. There are very specific rules how to totalize electricity usage, and these do not tend to be followed by the after market units. I suspect that the error is much worse at the bottom end of the scale of consumption. 

In order to reduce my energy consumption at home, I have done a few things... Firstly I replaced all my servers with a low end new dual core hyperthreaded machine running 4 GBytes of RAM and VMWare. On this I have installed about five different virtual machines. The software for this is free. I have also outsourced my email to sherweb so that I don't need to have redundant machines for email. I also have a few PC's that use about 5W each, and run them on USB thumb drives.

Anyone wanting more details can contact me directly. And, yes, I still work from home, but the business is just operating the background at the moment.

Thinking about, it should really be too hard to self monitor power consumption, total, circuit by circuit etc.... and even possibly work out power factors, I wouldn't doubt there is a setup somewhere on the market, usb to a computer and store everything, do your own calculations and then you could check these smart meters...

Any bets on their accuracy :-)
