Dear Gurux Team,

I hope you are doing well.

We are currently working on the development of electricity meters and are interested in implementing a DLMS/COSEM stack in our Renesas Controller. We would like to understand whether Gurux provides a DLMS stack suitable for integration into meter firmware, along with details regarding licensing, commercial usage, and technical support.

Kindly share the relevant information and documentation to help us evaluate the solution.

Looking forward to your response.

Hello,
I'am trying to read multiple objects with 1 query via tcp/ip using python.

Running this code:

obj1 = GXDLMSRegister()
obj1.shortName = 39656
obj1.attributeIndex = 2

obj2 = GXDLMSRegister()
obj2.shortName = 39800
obj2.attributeIndex = 2

objects = [obj1, obj2]

packets = client.readList(objects)

for p in packets:
reply = send_and_receive(p)
client.getData(reply)

gives me an error:

hi Am trying to connect the Gurux GXDLMS Director to the landisgyr meter and it has a CU-XE communication module. There are no Obis codes in the software, and it says failed to receive reply from device. can you help? I can only connect with the MAP110 from landisgyr but with Gurux is giving me problems.

Hi,

Attribute 4 of ActionSchedule return DayOfWeek is 1),
but as a result GXDateTime has DayOfWeek as FF

Why is this happening?
Can something be done about this?

Hello,

we intend to use the Gurux DLMS .NET stack for a system that needs to communicate with a large number of smart meters in parallel.

Our application architecture is fully asynchronous and uses async/await throughout the entire call chain. However, we have not found any indication that the Gurux DLMS stack supports asynchronous communication.

From what we can see, communication appears to be implemented using synchronous/blocking socket calls.

Our concern is the following:

I am using two L&T Trivector meters connected through RS-485 looping with a USB-to-Serial converter. Earlier I asked about multiple connections in the Gurux forum(https://www.gurux.fi/node/35203). I created a sample program using the Gurux DLMS Client in C#.

The issue I am facing is:
When reading data from one meter, if I power ON the second meter, the current meter stops responding.

I suspect there may be a communication conflict or addressing problem in the RS-485 multi-drop setup.

Hi,
I am using gurux_dlms for python and I would like to know how to configure the translator properly
Here is my code

Hello Gurux Team,

We are currently facing an issue while reading meter data using the Gurux DLMS libraries.

In the field, some meters display six-digit KWH values (for example, 987654.32). However, when we fetch the value from the meter using GXDLMSDirector, we receive only five digits (for example, 87654.32).

The meter display shows the correct six-digit value, but the response appears to be skipping the first digit in the reading.

Please let us know if you require any additional logs, OBIS codes, or sample responses from our side to investigate this issue.
