Hallo Community!
Vielleicht hat ja jemand hier einen guten Tipp für mich.

Ich suche aktuell ein Stromzähler welchen ich einfach an OpenHAB anbinden kann.
Die Vorgaben sind:

  • 3 Phasen
  • 230/400V
  • Für 16A ausgelegt
  • Anbindung via RJ45
  • Muss offline laufen (Zähler hat nie im Leben Internetkontakt)

Ich hab mal im Netz gesucht, aber die meisten lassen sich nur per S0 oder RJ485 anbinden.
Das erfordert Zusatzgeräte.
Kennt jemand einen guten und günstigen Stromzähler, welcher per LAN (oder WLAN) mit OpenHAB ausgelesen werden kann?
MQTT oder Zigbee wäre auch als Anbindung möglich.

Der Zähler kann auf einer Hutschiene oder an einem Zählerplatz im Schrank montiert werden, da bin ich recht flexibel.

Hello Community!
Maybe someone here has a good tip for me.

I am currently looking for an electricity meter which I can easily connect to OpenHAB.
The specifications are:

  • 3 phases
  • 230/400V
  • Designed for 16A
  • Connection via RJ45
  • Must run offline (meter never has internet contact in life)

I searched the net, but most of them can only be connected via S0 or RJ485.
This requires additional devices.
Does anyone know a good and cheap electricity meter, which can be read via LAN (or WLAN) with OpenHAB?
MQTT or Zigbee would also be possible as a connection.

The meter can be mounted on a DIN rail or at a meter location in the cabinet, I am quite flexible.

Only needs internet connection for firmware update.

In case Z-Wave is an option: https://shop.zwave.eu/de/artikel/strom-energiemesser/688/aeotec-zangenamperemeter-mit-drei-zangen-gen5-60a?c=19

@hmerk Thanks for the tip. I somehow overlooked it while scouring the Internet.
@Oggerschummer No, Z-Wave is currently not an option. Have everything set up with Zigbee and would have to buy everything fresh for Z-Wave.

Search for “power”:

BUT:
Please make sure that your setup (ZigBee Binding, MQTT, …) is compatible with the ZigBee device chosen. Do not assume that Tuya devices are compatible with the ZigBee Binding. Check the csa database for ZigBee certified products. Devices without CE declaration might get confiscated by the customs.

Might be impossible to source:

Not sure about your budget, but devices should be available in DACH:
