[mrtg] Measuring a closing circuit

I have a electricity meter that has a closing relay for a specific
number of Wh that my house uses. That means that I can add 0-24V to
that relay and get a pulse for each time the number of Wh is consumed.


Then it must get into the computer and in to MRTG.

Is there anyone that has done something similar that I might benefit from?

I have no problems creating circuit boards from descriptions and can
easily add this to the parallel port, but my programming sucks. :-)

I have both linux and windows-servers running with MRTG right now.

Thankful for all help I can get!
