I am reaching out for guidance regarding my recent endeavor to establish communication with a DLMS smart meter using Holley meters. As someone new to this domain, I am currently navigating the initial setup phase and encountering some difficulties.

I can use the ECDSA suite1 and One-Pass Diffie-Hellman connect to the meter. But when I read the data from the objects,it shows "Object reference not set to an instance of the object. "
And I try to change the key agreement from one-pass to none，then I can read the data successfully. So Why does this error occur？

The log is below:

Hi, I am trying to read load profiles for a Sanxing meter. Could you please take a look at the flow and expand why I am getting an invalid data type at the end of this?

Thanks

I select "Certificates tab from the "Security setup" object. Then press "Key pair". The error is “access error Device reports a inconsistent Class or object ”.

Hi
I tried using Simulator（Java） as the meter，then i use the Director to read the meter。When I connet to the meter without Authentication，it works successfully。But I use the HighGMac，there are some issues here。Show that LLC bytes are missing from the message。

the sever log is below：
Client address: 1 HighGMac authentication, Client address: 1, password:

Hi there.

I'm new to the DLMS world and currently using this wonderful tools to help with meter development.

I just don't know for these two frames, why the len field in the parsed xml doesn't match the actual frame
e.g.
* First frame's len is 0x0A but in XML it is "C"
* 2nd frame's len is 0x23 but in XML it is "22"

Could anyone help to explain this?

Thx!

Good day developers and communities,

I have project to connect meter EMH LZQJ-XC with Gurux GXDLMS director using serial interface. The information for this meter is very limited in the web. Please help me to configure this meter as my deadline for this project is near. I already try the default setting for the EMH meter but it failed.

Hello Mikko,
I have implemented object with Proprietary attributes (Blue Book:„Proprietary attributes may be added: these shall be identified with negative numbers.“).
This is a part of packet with Object List (when perform Refresh in Director):
"
...60100010102020F01160002041200011100090600005E2735FF0202010702030F

0216060002030F /* attr 02, access 06 auth.read/write */
FF16000002030F /* attr -1, access 0 no access */
FE16000002030F /* attr -2, access 0 no access */

i could not see in the data tab even receive it as in log. here is my log:

Hi,

I'm having some trouble reading my Itron/Actaris SL7000 meter. its a 2021 meter of type SL761.

I can connect to the meter using DLMSDirector with no authentication. But I want to read some of the energy values, as well as the clock and serial number. I can read this for a Landis+gyr meter using a java application with the GuruX library and want to be able to read the SL7000 the same way.
