Hi, yes, the project is very raw at this point. Thanks for pointing out this deficiency.

I am using an AdaFruit TSL2561 light sensor taped over the infrared LED on my electric meter. It is wired up to the i2c pins on a Raspberry Pi over a cannibalized cat5 cable. The project only works with this setup right now, and your meter must have an IR LED that blinks for every watt-hour used. You can check for this blinking with a digital camera.
