Kamstrup DIY Energymeter
thingiverse
The Kamstrup energy meter reading can be accomplished using an optical protocol, which involves a 3D-printed reading head equipped with two IR LEDs. Access detailed instructions (in Danish) at http://wiki.hal9k.dk/projects/kamstrup to learn how to manufacture the PCB from the provided Kicad sources (kamstrup-v2.zip), or use the Eagle version by @boelle (eagle-kamstrup-by-boelle.zip). Ensure that you 3D-print the enclosure and drill the holes to correct diameters (5mm for LED holes, 6mm for magnet holes) for a snug fit. The enclosure features four bottom holes for fitting four magnets like http://www.supermagnete.de/eng/S-06-06-N, which help hold the enclosure onto specific Kamstrup meters with metal rings.
