Does it matter?
If your initial usage is n power monitor units and after a week of discovering what takes unnecessary power the usage is n/2 power monitor units then you are saving money.
Don't forget to set the unit price at 41p to show your kids how much "green" energy costs.
My CurrentCost is pretty damn close, maybe half a unit/day out on about 20 units. I did find that the clamp is pretty sensitive to cable position and orientation. The most accurate result is with the cable tight to the inside of the jaws and the cable running at right angles to the clamp. Just clipped around hanging loose isn't good enough.
I was thinking of providing a single 12v supply for all the switches/routers/AP's etc but hadn't found a "nice" connector for the distribution. Borrowing 12v from the servers PSU is a good idea, I already do that for the VFD display attached to it. And thinking a bit further a couple of chocolate blocks and bell wire terminated in plugs for the kit would do for the distribution...
I was thinking of running a molex connecter to a spare PCI slot like this
I have the speech software, it just needs to be a textual file or stream of a recognised type. As you say pretty boring but not as useless as an energy monitor that is silent in a house with nobody who can see it!

You need a fuse.. I have seen the wires glowing red after a 12V PC power supply has been shorted. They lasted a good few minutes as we left it on to see what would fail first. The potential for a fire is quite high.
Got any O's?
