Power usage meter
So, I want to track the power usage of our house. My entrance power meter outputs an IR flash for every 1kW consumed, so that's easy to measure without any need to buy any special equipment. Unfortunately, the meter is pretty far from my computers to directly connect up for display or logging.

I figure I'll need to use a basic Arduino and IR sensor (maybe a Diavolino) to detect the IR pulses, then accumulate the consumption so I can total it up on a monthly basis. I'll probably manually reset it every month, though I'd like to add a RF packet transmitter so that I can remotely log it on my Linux server at some point.

At some point, I'll try to tie it into EMoncms.
In the meantime, I'm going to get an LCD screen LCD Scren from ICStation and use that to display the results. It should be enough room to show total consumption, time period, average consumption, and maybe display peaks and/or recent consumption.
