Consultant needed for reading and sending tokens to DLMS meter from ESP32

Forums
General discussion

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.

invocation counter issue

Forums
Gurux DLMS for ANSI C

Hello,

I have two variants of energy meters. I have taken the GuruxDLMSDataCollector example for dlms client integration in my MCU. One of the meter is working fine reading obis profiles without "update Invocation counter". But another meter needs Invocation counter this i verified with Gurux director so it needs "Invocation counter". So can you provide a piece of code for my micro controller for to read "Update Invocation counter".
It's urgent if possible can you provide me ASAP.

Regards,
Srikanth Jogi.

Defining a Structure on server

Forums
Gurux DLMS for ANSI C

Hello.

Im triying to create a COSEM object class_id = 1 (DLMS_OBJECT_TYPE_DATA) of type structure. This structure will contain 4 different values. First 2 of them will be uint32 and last 2 will be int32.

The way i'm creating this object is the following:

gxData myMEASURES;
static dlmsVARIANT vUA, vIA, vPA, vQA;
uint32_t g_rmsUA, g_rmsIA;
int32_t g_rmsPA, g_rmsQA;
#define MAX_MEASURES 4
static dlmsVARIANT arrElements[MAX_MEASURES];
static variantArray arrBuf;

How to configure TLS communication and add CA certificate in Gurux DLMS Director

Forums
DLMSDirector

Hello,

I am working on a smart energy meter project and would like to establish a secure TLS communication using Gurux DLMS Director.

I have a few questions regarding the configuration:

How can I add or configure the CA certificate, client certificate, and private key in the Gurux DLMS Director tool?

Where should these certificates be placed — under Integration settings or Device credentials?

Is there any documentation or example available for setting up TLS/SSL (Port 4059) communication with a DLMS meter using Gurux tools?

Meter main 4mb eeprom memory ciphered

Forums
General discussion

Hi Mr. Mikko, I would like to ask you about the blockCipher and Authentication keys . I try to find the keys inside meters the main 4mb eeprom memory where the security keys is stored. The meter saves the most data(not all) ciphered in the main eeprom memory and I can’t locate the address with the saved keys. I have read with programmer the eeprom.
Is there some software to “translate” the ciphered hex dump of the eeprom memory?? Is it possible to help me?
I have been trying for months to do that with no success.

Regards Lambros
