Hi,

We are getting this data-(energy values mapped to OBIS code) from Secure make Premier 300 DLMS Meter in the cloud. Need guidance to convert these values to arrive at the cumulative energy reading in KWH. Have checked the physical meter reading today - Cumulative Active Energy - 88.92KWH

Hi

What kind of encryption and decryption mode of aes is used for encrypting and decrypting the HLS secret if the authentication mechanism if just high level.

Please try to answer ASAP.

Thank you in advance.

Hi,

I am new to the forum. I wish to consider using DLMSDirector together with a PLC modem to be able to identify and read L&G E460 PP meters and their CUI on the same power reticulation network.

Dear Sir,

Is it possible to read meter using optical read head and Arduino client code.

Arduino setup code

GXTRACE(GET_STR_FROM_EEPROM("Start application"), NULL);
BYTE_BUFFER_INIT(&frameData);
//Set frame capacity.
bb_capacity(&frameData, 128);
Client.init(true, 16, 1, DLMS_AUTHENTICATION_HIGH, "****", DLMS_INTERFACE_TYPE_HDLC);
//Un-comment this if you want to set system title, block cipher key or authentication key.

I am using a PL2303 based USB to RS232 converter which has 4 wire (TX, RX, GND, VCC).

I have connected RJ11 (4 pin) connector as per the meter ER300P datasheet.

I am yet to test this cable with the meter, wanted to confirm if this will work as I don't have access to the meter and need to test the cable in the field.

Any help on this is highly appreciated.

Hi,
I am trying to use ""Gurux translator" testing long set with multiple obis by block.
Using the example of the green book, I get the following error:

Hello everyone,

I am researching about the use and implementation of Public Key Infrastructures (PKI) both open source and paid technologies in Advanced Metering Infrastructure (AMI).

Any recommendation of any open source PKI that I can investigate, in the case of GURUX DLMS AMI4, does it have PKI capabilities?

thanks

slds,

Hi

How do I define the serial port that I will use on the STM32CubeIDE to connect to a power meter with an optical probe?

This is my code and I have two usb serial ports:

/* Initialize all configured peripherals */
MX_GPIO_Init();
MX_USART2_UART_Init();
MX_USART1_UART_Init();

/* USER CODE BEGIN 2 */

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:
