Hello,

I'm currently testing DLMS communication over Android devices, and I've noticed that some VPNs cause the connection to drop or timeout intermittently when trying to read meter data remotely.

After several trials, I found that using Stag VPN actually resolves the issue. The communication remains stable and meter responses are consistent, even when routed through the VPN. I’m curious—has anyone else here tried DLMS/GXDLMS communication over a VPN? What’s your experience?

Any insights or alternative setups that work reliably would be appreciated.

Hello Mikko,

I have a few doubts regarding communication with energy meters over Bluetooth. Specifically, I would like to understand:

When we say that an energy meter supports Bluetooth communication, does it mean that the meter comes with built-in Bluetooth capability?

Or do we need to externally connect a Bluetooth module to the meter in order to enable Bluetooth-based communication?

I would appreciate it if someone could clarify this for me, especially in the context of commonly used smart energy meters.

Thank you in advance!

Hi,

Can someone explain in simple terms how reading load profile data works on an L+G E560 meter?

Hii

I'm using below Gurux python client to read meter data.

https://github.com/Gurux/Gurux.DLMS.Python

Now I want to write to the meter objects. Is all the object attributes of a meter is writable? How to check it?
How to write meter objects using gurux python client?

Good morning.
I'm simply trying to verify why the DSO can no longer read, via the GSM modem system with SIM DATA CSD,

The Modem-GSM system seems ok.

I also wanted to test the operation of the "Utility's Port" of the meter with my pc (3 wire conection?).

The meter is Actaris Itron - SL7000 761 - FW 6,24 (2013)

I think Gurux is fine for this test.

After some trial and error I entered the configuration below

Hi,

I can able to read meter data using obiscode but there is a situation to send custom commands to meter(proparatory command).How we can do this.

Thanks in advance

Hi Team,

I am looking for parameter code and OBIS code mapping for the Indian region so that we can generate CDF/XML files from our software.

Is there any documentation for reference?

Hello everybody!

I am trying to create wireless DLMS client for Nartis emeter, based on my own hardware (STM32 MCU & CMT2300A transceiver).

By logic analyser i can see all the traffic between remote control panel and meter, but I can't understand what kind of information is being transmitted. Most likely, encryption is used when transmitting data wirelessly.

Is there a description anywhere of exactly how data is encrypted during wireless exchange?

Hi
is there a method to get the UIValue based on the actual
value read in the meter?

for example, I have a GXDLMSData that has a custom 
attributesettings that defines GXObisValueItem like 
for example:
GXObisValue Value is 1 and UIValue is Reset

right now I am manually matching them

GXDLMSAttributeSettings atbr = dataobj.Attributes[1]; 
if (atbr.Values.Count > 0) 
{ 
	foreach (GXObisValueItem val in atbr.Values) 
	{ 
		if (dataobj.Value != null &&
			int.TryParse(dataobj.Value.ToString(), out int parsedValue) &&
			val.Value == parsedValue)
