DLMS Client Java

Forums
Gurux.DLMS

I am using the gurux client Sample from the github repo in the following link https://github.com/Gurux/gurux.dlms.java/tree/master/gurux.dlms.client…

I run it with provided argument I got the available meter that I have access to in XML file, but I don't how the get data received from meters and which function to use to return the data so I can store it in a json file and push it my pipelines.
anyone have an idea about that I will appreciate any help.

hwo to connect to Genus meter via HighSHA256?

Forums
DLMSDirector

The "Authentication" drop-down for Genus meters only shows "None", "Low", and "HighGMAC". how do i add "HighSHA256" to that list? yes, the meter definitely supports mechanism 6.
I see that the goe.obx file that's downloaded from the website only has those 3, but I can't see a way to edit that file, and I can't see a way to do this in the Manufacturer Settings dialog, either.

How to encode authentication mechanism name as octet string in AssociationLogicalName

Forums
Gurux.DLMS

Hi,

I am trying to enable/disable HLS security on E360 meter from Landis. I am having troubles with how to generate correct frame for GXDLMSAssociationLogicalName object. I am trying to write "AuthenticationMechanismName" (attribute 6) to the meter but I would need to encode it not as a struct but as an octet string, could you help me with that?

This is an output frame that I am currently getting:
C104C102000F0000280002FF0600004000002B0000FF0200020207110211101202F411051108110211011600

dayOfWeek initialized with 0 instead of 0xFF

Project
Gurux.DLMS.Python
Status
Closed (fixed)

Reported for Version 1.0.178.

In the GXDateTime class, the variable self.dayOfWeek is initialized with "0" -> https://github.com/Gurux/Gurux.DLMS.Python/blame/9575fe600e643b0f43385d…

If a meter sends 0xFF for the dayOfWeek this value will not be updated and the resulting GXDateTime object will have "0" instead of "0xFF" for the dayOfWeek property -> https://github.com/Gurux/Gurux.DLMS.Python/blob/9575fe600e643b0f43385db…

In the C# code however DayOfWeek is initialized with 0xFF and therefor does not have this problem -> https://github.com/Gurux/Gurux.DLMS.Net/blob/446e1914e1c6d06061c190e2f1…

So self.dayOfWeek should also be initialized with 0xFF in the python GXDateTime class.

How to decrypt RF433 data from/to DLMS Emeter?

Forums
General discussion

Hello everybody!

I am trying to create wireless DLMS client for Nartis emeter, based on my own hardware (STM32 MCU & CMT2300A transceiver).

By logic analyser i can see all the traffic between remote control panel and meter, but I can't understand what kind of information is being transmitted. Most likely, encryption is used when transmitting data wirelessly.

Is there a description anywhere of exactly how data is encrypted during wireless exchange?

I can't connect the MT880 CM-LTE-3 modem meter to Gurux in DLMS.

Forums
Gurux.Serial

Hi,
I connected the CM-LTE-3 modem to the PC through RS485-USB converter. I set Gurux with the parameters:
-Iskraemeco
-HDLC
-Authentication none
-Client Address 46 (30+16)
-Logical Name Referecing on
-Physical Server 11
-Logical Server 1
-Serial COM4 9600 8N1
-DLMS standards
But the MT880 doesn't answer me. "Failed to receive reply from the device in given time".
