Dsmr (p1)

[tsmit (Tom Smit)]

For as far as I know the dsmr binding doesn’t support an ethernet connection like the OTGW does.

As suggested here you could look into using an Arduino or ESP and publish to MQTT:

How to get P1 telegrams from remote RaspberryPi?

In my setup the OpenHAB server runs on a Ubuntu server. On a remote raspberryPi I have connections to a DSMR electricity meter and a Landys & Gyr UH50 heat meter. The DSMR binding expects the OpenHab server to have to connection to the electricity meter. Does anyone have a suggestion on how to get the electricity consumption data into OH? Thanks, Niels

I Googled and found this: GitHub - sandervandegeijn/P1-Meter-ESP8266-MQTT: Software for the ESP8266 that sends P1 smart meter data to MQTT (without CRC checking)
