HAN-port reader for power meters with "P1 companion" interface

Used on smart meters with HAN-port according to DSMR P1 Companion Standard (with RJ12 connector).

Note: The term "P1 port" is in some mid-European countries used on power meters that deliver M-bus signal on pins 3 and 4 of an RJ12 socket, which is not "P1 companion". Those meters cannot use Pow-P1, the right product for those meters is Pow-U.

Norwegian customers: P1-port is not used in Norway.

Order without 3D printed holder if you prefer to 3D print an enclosure yourself (contact us to receive free STL files).
