hi
I need to connect my meter with IEC 62056-31 protocol

Part 31:
Use of local area networks on twisted pair with
carrier signalling

it possible ?

I'm running a research project where we want to collect some readings from a smart meter that produces a public-key signature. We don't need to actually use the meter in any real deployment - it's purely a proof-of-concept experiment for a research project in cryptography. All we need to do is hook it up in a lab, and grab some readings from it on a computer.

Here is an example of hexadecimal data received from the HAN port of a Kaifa MA304H4PSE:

7e a0 9a 01 00 01 10 12 10 e6 e7 00 0f 40 00 00 00 09 0c 07 e7 0a 14 05 12 3a 0f ff ff c4 00 02 12 09 07 4b 46 4d 5f 30 30 31 09 10 37 33 34 30 31 35 37 30 33 30 39 30 34 30 34 35 09 07 4d 41 33 30 34 48 34 06 00 00 01 a9 06 00 00 00 00 06 00 00 00 00 06 00 00 00 04 06 00 00 00 61 06 00 00 01 ac 06 00 00 05 c4 06 00 00 08 fa 06 00 00 08 fe 06 00 00 09 0f 09 0c 07 e7 0a 14 05 12 3a 0f ff ff c4 00 06 00 07 4b b5 06 00 00 00 00 06 00 00 64 3c 06 00 02 6e f6 4b 0b 7e

Is there a Gurux.DLMS package for OpenWRT in the .ipk installation package?
If not, how can I install the libraries on OpenWRT myself?

I am new to to smart meters, I was recently checking out a smart meter system, the gateway is a esp8266 which communicates to the data collector over mqtt with some hex format. other meters connects to the gateway meter with some sort of rf mesh NAN with 32 bit meter address similar to ipv4. the data collector publish to the topic with the name of the grid id of the gateway meter.

Hello guys, im a total newbie on the subject of smart meters and DLMS

would anyone be willing to spend some time on a chat, explaining to me the basics of how to get started? Id be glad to pay for the effort

can we write the disconnection control ones meter has connected. Can you tell how ?

Hi,

How can I implement and replicate in ANSI C, in the client side of the program, the action of Capture Objects of profile generics.

This is the dialog GXDLMSDirector shows when I press the Capture action:

12:50:08 Method object 1.0.99.1.0.255, interface ProfileGeneric
TX: 7E A0 1B 03 23 76 89 D6 E6 E6 00 C3 01 C1 00 07 01 00 63 01 00 FF 02 01 0F 00 73 A3 7E
12:50:08
RX: 7E A0 11 23 03 96 21 CD E6 E7 00 C7 01 C1 00 00 FC B4 7E

I want to implement in C this action, in the client side, but I don´t know how to do it.

Thanks.

Hi kurumi

Hi, I was reading the DLMS green book, where it explains priority management and says the following:

"9.1.4.4.4 Priority handling
For data transfer services using LN referencing, two priority levels are available: normal (FALSE) and high (TRUE). This feature allows receiving a response to a new request before the response to a
previous request is completed.
