Hi Team ,
I am planning to implement the DLMS protocol in Python using the Gurux-DLMS library. I have a few questions regarding how data is transmitted through the gateway, how connections are established and maintained, and how communication happens with the meter.
We have gateways in place, and I would like to understand what type of gateways are supported by DLMS meters. Additionally, I want to know the communication media involved (similar to Modbus TCP/IP) and the complete end-to-end flow.
Specifically, I am looking for clarity on:
How the gateway communicates with the DLMS smart meter
What communication protocols or media are used
The structure of DLMS packets
How data transmission takes place between the meter, gateway, and backend
This information will help me proceed with the implementation effectively.
Thank you.
Hi, DLMS is not an easy…
Hi,
DLMS is not an easy protocol, but it's well documented in several standards.

It's not possible to describe the standards shortly.
You need to ask the meter manufacturer whether the gateway is supported.
There are differences between meters, and not all GWs work with all meters.
