I have made a configuration on "Register Activation" class but attribute index data 3 is not visible on GxDLMS Director. Instead of data it is showing following system Generic list as

 System.Collections.Generic.List'1[System.Collections.Generic.
KeyValue2[System.Byte[].System.Byte[]]]

 System.Collections.Generic.List'1[System.Collections.Generic.
KeyValue2[System.Byte[].System.Byte[]]] 

Tariff log of all attribute index are (rest attribute index data is visible on GxDLMSDirector screen) as 1

Hi

I want to Know while reading data from meter do we need to apply the scalers to the meter data separately or else gurux will automatically apply scalers to the meter data.

Please clarify this doubt.

Thanks

I am using a Holley DTS545 smart meter. How can I add objects manually with OBIS codes? And how can I know it's working?
I attached OBIS codes of my meter's objects.

Hi,

I am trying to connect to a Sagemcom T-210D using Suite 1 (AuthenticatedEncryption) and HLS-5 (HighGMAC).
I could successfully import the client certificate using the public client, however, logging on to the management client fails.

Hello Mikko,

As written in blue book 4.5.4 Special days table, methods insert/delete are optional. Gurux DLMS Director Add/Remove buttons in special days table objects unavailable for selection if methods insert/delete are not realized by meter manufacturer.

Is it possible to add Director functionality to modify Special Days table via ordinary set/get request?

Best regards, Andrew

Dear kurumi,

Hope you are doing well.

Excited to become on forum after long time it's around 2.5 years.

I am developing indian standard and for that i have implemented firmware upgrade association but gurux gives error on object list downlow.

Error : Index was out of range. Must be non-negative and less than the size of the collection. Parameter Name: Index

Hi

I need to test HLS GMAC authentication for the Landis+Gyr E570 meter model (Client ID: 1). However, High GMAC authentication is not available for the E570 model in Gurux Director.

Hi everyone,

I'm using GXDLMSDirector to connect to a Landis+Gyr E550 meter. The connection is established successfully, and I can read the basic DLMS/OBIS object structure.

However, I'm facing an issue when trying to read the actual parameter values - most attributes return a NoAccess status. As a result, I can't retrieve the data.

I've attempted to switch the authentication level to Low and High, using the commonly known passwords 00000000 and 12345678, but access to these attributes remains blocked.

Hello Mikko,

There is a a small bug in recent Director functionality, though I can't recognize is it a code problem or a directive trouble (#if !NET5_0_OR_GREATER || WINDOWS_UWP)

I'm working with Activity Calendar object, Passive calendar tab, Day profile tab.
While trying to add day profile action with a start time field "00:00:00", I'v got a message that string is not recongized as a valid DateTime Value.

Hello everyone,

I'm working on a tool to virtualize a low-voltage TLSBT meter using the Gurux.DLMS.Net simulator. I cloned the real device using GXDLMSDirector and generated a valid XML file, which I load into my simulator using the official GXDLMSMeter.cs class.

My goal is to replicate the behavior of the real meter, where, upon connecting with ClientAddress = 1, I can see multiple GXDLMSAssociationLogicalName objects listed:
