Are there any example implementations of DLMS/COSEM servers that use ECDSA for High-Level Security (HLS) authentication?

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

Hi all,

We have ~500 ameter300 DLMS meters deployed across the country. They all use the same key material (system title 5753450000000001, client title 434C4E5400000001, auth key D0…DF, block key 00…0F, GMAC password 0x3333…). The legacy OPC client (C# / MyDaAddressSpaceDevice) talks to them just fine, but it hardcodes Ciphering.InvocationCounter = 1.

Hello, everyone

I want to connect the simulator meter with the template (LN-v2-GMacWithAuthenticationEncyption.xml).

I started the simulator with command(.\bin\Release\net9.0\Gurux.DLMS.Simulator.Net -S COM3 -t Verbose -x .\Templates\LN-v2-GMacWithAuthenticationEncyption.xml)

After that, i started the command to connect( no issue with the physical layer), but it did not work, the aare is failed. is my command wrong? or other ? i need help. thank you for looking.

Hi Mikko,

<Array Qty="01">
<Array Qty="02">
<Structure Qty="02">
<OctetString Value="070000FF"/>
<OctetString Value="060000FF"/>
</Structure>
<Structure Qty="02">
<OctetString Value="080000FF"/>
<OctetString Value="090000FF"/>
</Structure>
</Array >
</Array>

hi dears , an iskra M3 meter always delay more than 2 years even after synch with system time, What could be the most important reasons? thanks in advance

Good day all. I want to take readings from a DLMS meter to an ESP32 and send tokens from ESP32 to the meter.

1. I need a mentor. I am willing to pay for your time
2. I need a meter manufacturer suggestion that can give me this functionality. I will order a test sample

Thank you.
