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.

used GXDLMSDirector and everything works fine. But when I try to use C example client with these arguments:
./gurux.dlms.client.bin -h localhost -p 4061 -c 22 -a HighSHA256 -P Gurux -T 4142434445464748
I get error:
Connecting to localhost:4061
InitializeConnection
Access Error : Device reports Read-Write denied.

Also tried to use .NET client and everything works fine.

Hi Mikko,

Happy new year !

I need your advice please, I have to make some tests on indian meters (Capital Power System and L&T), this 2 meters have 2 connection types (HDLC with optical probe and 4G modem).
I am facing a problem, I didn't manage to connect them here in France, I have tried several telecom operators but I see a GRPS connection failed error code on the meter and the APN doesn't give me an IP address (the 2 cosem objects ip4setup and ip6setup remain empty).

When I am reading the billing profile date the timestamp is getting as hexadecimal is there any way to convert it into readable form?
This is the output I am getting
