Dear Sir,

I have read the values of the L&T meter using the DMLS director and optical cable. It is working perfectly, and its interface settings are HDLC with MR authentication

After that, I am trying to read the L&T meter using Arduino. In the Arduino development folder, it shows three programs: client, server, and pushListener. From these which programs should I use for meter reading using HDLC with MR authentication

Hi

Client.ino compile in Arduino IDE 2.3.3 compile without problems using ESP32 or ATMEGA boards, but when I change to STM32 (STM32Duino) board several erros occur:

Hi,
I want to read energy meter using Arduino mega 2560 via DLMS. I downloaded the Arduino_IDE and copied include and src into client folder.The code compiles and get downloaded in Arduino but i dont now what i need to do next?
At the moment i do not have a meter. is there any way i can simulate meter that i can test communication with my mega2560?
Also are there any arduino ide mega client working examples that i can check?

Gurux DLMS for Arduino IDE

I am trying to connect with Secure Premier 300 with RJ11 port and RS232 protocol. It's and Indian Standard DLMS meter.

Can anyone help me with the pinout for the RJ11 port? Is it standard among all meters with RJ11 RS232 or varies from manufacturer to manufacturer?

Any help is appreciated.

Dear Mikko,

I am using an Indian smart meter for testing, In while reading data from the meter we are getting the following response randomly.

Can you please suggest when this error response sent by the meter?

Hello Gurux Forum,
I am using the Push Listener to read data from the ISKRA AM550.
All good for now - but what I found out is that the meter pushes every full hour (f.e.: xx:00:00) one (1) frame that comes along with strange data.
I tried to contact the grid service and Iskra themselves but no answer for now.

Anybody knows what that is and how to handle it?

Thanks for any kind of feedback!

Here one frame/readout example:

Hello.

I have had problems changing the watch. I am using the Python library and I have tried several examples like the following found in the forum but I can't get it.

reader = GXDLMSReader(settings.client, settings.media, settings.trace, settings.invocationCounter)
settings.media.open()
reader.initializeConnection()
reader.getAssociationView()

clock = GXDLMSClock("0.0.1.0.0.255")
fecha = GXDateTime(datetime.datetime(2024, 9, 3, 13, 0, 0))
clock.time = fecha
reader.write(clock, 2)

Hi
I am trying to set some sort of security level to test the Meter.
For example
by default the security for Manager level is :
Authentication: HLS_GMAC
Use Dedicated Key: True
Application Context: LN-With Ciphering
in the properties section.
My question is:
Where can I change these parameter to something else..(Where is the Location).
like where can I set Authentication to LLS instead of HLS_GMAC?
and what is the meaning of use dedicated Key: False

want to know concept of block response from server C4 02. What's difference between C4 01 normal and C4 02 block is there size of data matter??
