Pow-U

HAN-port reader for M-bus power meters

Used on two categories power meters:

  1. Power meters in Norway and Sweden with HAN-NVE interface (RJ45 connector; same as for Ethernet).
  2. Power meters in other countries that delivers M-bus signal to an RJ12 connector. If in doubt, consult your grid company or email us before placing order.

For Kamstrup Omnipower meters, Pow-K is a better and less expensive solution.

Order without 3D printed holder if you prefer to 3D print enclosure yourself.

Note: This products is NOT compatible with the Smartmeters installed in Germany, even if those have an RJ45 socket.

Frequently asked questions

Which cable should I choose?
RJ45 if your meter has a HAN-NVE interface (RJ45 socket – common in Norway and Sweden). RJ12 if your meter delivers M-bus on an RJ12 socket. Check your meter model in the Selection guide.

My meter has a "P1 port" on RJ12 – Pow-U or Pow-P1?
In some European countries "P1 port" is used for meters that deliver M-bus on pins 3 and 4 of an RJ12 socket. Those meters need Pow-U. Meters with a real P1 companion (DSMR) interface need Pow-P1.

Can I use Pow-U on a Kamstrup Omnipower meter?
It works with a Kamstrup HAN-NVE module, but it may then be necessary to power Pow-U via USB. For Kamstrup Omnipower, Pow-K is the better and less expensive choice.

Does Pow-U work in Germany?
No. Pow-U is not compatible with the smart meters installed in Germany, even if they have an RJ45 socket.

Does Pow-U need a cloud service or an app?
No. Pow-U connects to your local Wi-Fi and has its own web interface. Data is sent locally via MQTT, with Home Assistant auto-discovery.

I am not sure if my meter is supported. What should I do?
Check the Selection guide, ask your grid company, or contact us before ordering.
