Hi, this is Juan From colombia, for the last days i`ve been working with the landis+gyr e 650 Model:ZMD402 & the CU-E22.
I`m gonna talk you about what i wanna achieve, and maybe you could help me with that.
Ok, from the last days i've been trying to connec the landis from the CU to python, i already know which port i have to use and all the security information.
I try with wrapper and HDLC but i dont manage to make it work.
Usually the device open the tcp and arrq, after that he makes the request from tx-AARQ with the information bytes.

We tried to follow your description about the pre-established connection:

As we understand it, in this mode the meter should continuously send data to the client, and the client should just listen without establishing the connection itself.

A few things are unclear:

Hello everyone,
Does anyone have a verified working wiring diagram or screenshot for the RJ11 to RS232 pinout on the Secure Premier 300 meter?
I’m specifically looking for a confirmed setup that has been tested successfully. Any reference images or pin mapping details would be greatly appreciated

HI any one with connecting experience of GENUS SUGAM 3P4W bi directional with DLMS??. can guide me??

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:
