They have chosen to use Echelon NES system components. Recently I got an EM-1023 Poly-Phase (PDF) installed which includes an ANSI C12.18 compliant infrared optical port.

The power company can now follow my electricity consumption from day to day and... so could I... if only I could interface to that meter. Which leads to my question: where can I find a reference implementation of the ANSI C12.18 (or similar PSEM) protocol? I have the specs and can write everything from scratch but why reinvent the wheel?"

I cannot conceive that anybody will require multiplications at the rate of 40,000 or even 4,000 per hour ... -- F. H. Wales (1936)
