Hello Sir,

Recently we got our Smart Gas Meter tested in CTT 4.3 release 103. The meter failed in APPL_OPEN_7: sub-test 1 (AFU Absent). Although, the Ciphering is not implemented in the meter, and this test gets Passed in GXDLMSDirector CTT.

My question is, Implementing Ciphering is mandatory to Pass the APPL_TEST_7 ?

Hello people,
i have a question about Arduino Client Example. My program simulator have some authentication:

Hello everyone,

I'm creating a new software for getting data from meter using python. For that i need to know how to get data individually using python. Can anyone please tell me how to do this. And I also tried https://github.com/Gurux/Gurux.DLMS.Python this in cmd, it's working.

Hello Gurux Team and Forum Members,

I'm new to this forum, and I apologize in advance if some text formatting isn't correct. I'm not a professional programmer, but I've been trying for several months to connect my ISKRA AM550 meter to my RPI4 and send data to Home Assistant via MQTT.
Unfortunately, I haven't had much success, and I could really use some guidance.

Hi, I have problems reading all association objects in WRAPPER mode. I don't see Clock, Limiter, SpecialDaysTable and other objects using the Python library (I use gurux-dlms 1.0.158).
GuruxDirector reads these objects without problems. (Authorization level is the same)

association_obj = GXDLMSAssociationLogicalName(ln='0.0.40.0.0.255')
association = self.reader.read(association_obj, 2)
print(list(association))

Hi,
Please tell me, is there a ready tool for password encryption using aes gcm 128?
I need to encrypt the new password with the current password and pass it to the association method 2.
Thanks!

Hello, wanted to ask if there is a tool how to parse association view PDU?

Reading association view gets me this payload:

(example):

Hello,

I am new to the DLMS protocol and I am working with the python example to get acquainted with the library and the protocol.

I am reading out a smartmeter and after I retrieved the Association view, I don't have all expected objects. I want to know the profiles, from PROFILE_GENERIC type.

However, I can read these objects in the director.

What could I be missing?

Thanks in advance!

HI,

I'm experiencing problems when I'm reading the entries of a profile generic. This happens only with one profile generic, and when I read more data than 40-50 rows.

This error doesn't happen when I try to read other profiles with more rows or more data per row. And I able to read this profile when I choose to read the last 40 entries or by date.

I'm able to read other profiles in multiple packets, so I'm not understanding where is my problem.

Dear Mikko,

We are currently using the Gurux.DLMS (C Language) library for meter testing. After configuring the DLMS client and attempting to read from the meter, we are encountering a "not enough memory" issue.

I've attached a screenshot for your reference. Could you please review it and provide your suggestions on how to resolve this issue?
