Hello,

I would like to evaluate my smart meter data with Java.

I am currently trying to decrypt the data using a sample from the operator
(https://www.netz-noe.at/Download-(1)/Smart-Meter/218_9_SmartMeter_Kunde…)

For this I used the following code.
https://www.gurux.fi/Gurux.DLMS.Secure (AES-GCM-128 AES-GCM-128)

public class DecryptDlms {

Hi,

i trying to recive values from itron meter using ReadRowsByRange, so i recive the array of data but the values are wrong, for example, the value should be 0.8966 but the recived value is 8966, and if the value is 140 the recived value is 14.

how can i solve that problem?

Good afternoon.
The task is that I need to read the values ​​for 1 day.

I am reading the ProfileGeneric and capture objects, and reading the information from the buffer.
Here is my code :

GXDLMSProfileGeneric profileGeneric = new GXDLMSProfileGeneric("1.0.99.1.0.255");
reader.read(profileGeneric, 3);
reader.readRowsByRange(profileGeneric, startDate, Util.getCurrentDate1());
reader.read(profileGeneric, 2);
But there are too many objects in the buffer around 4500.

I'm trying to a meter using an optical head with the following parameters:-
----------------------------------------------------------
client.setInterfaceType(InterfaceType.HDLC);
client.setClientAddress(*);
client.setAuthentication(Authentication.HIGH_GMAC);
client.setServiceClass(ServiceClass.CONFIRMED);
client.getCiphering().setSecurity(Security.AUTHENTICATION_ENCRYPTION);

Hi gurux team,

I'm trying to connect meter server example from github running on raspberry pi model 3.

When it try to connect lower than high authentication, it works successful with no errors.
But when it try to connect highECDSA authentication, it returns "Access Error : Device reports a inconsistent Class or object.".

Hi,

I'm working on a gprs energy meter system, i saw the code for dlms listener on github and i can and also went through the article on gurux website. I've one question that how can meter initiate connection and if meter initiates connection then why do we provide ip and port in the listener.

Thanks,

Good afternoon!
I am new to building a Gurux DLMS client. I need to connect to the counter and read the information. This connection must be made through an existing DLMS server. I used gurux.dlms.client.example.java for the example but my client is not connecting to the server. Have I chosen the right example to create a client?

Hi,

I ran the dlms simulator with parameters using command :
java -jar target/gurux.dlms.simulator.java-0.0.1-SNAPSHOT.jar -p -x crystal.xml -t Verbose -N 2 -X

when N = 2 i'm able to read data from DLMS client example in gurux's github repo using command :
java -jar .\target\gurux.dlms.client.example.java-0.0.1-SNAPSHOT.jar -h 10.0.8.8
-p 9654 -t Verbose -n 1

problem arises when i use N =3 or more in simulator command, after running simulator if i use the same client command, then i get invalid tag error.

Hi,
I'm trying to connect to several meters simulated on same ip and port, i tried using the server address but it works for first meter and gives invalid tag error for all other subsequent meters.

i've gone through some related questions on forum and found that normally you need to create multiple instances of GXNet, but in my case there's only single ip and single port, do i still need to create multiple instances?

Good day,

I'm trying to read the Load Profile of a Landis+Gyr e460S but am not sure if I'm doing it correctly. I can read the instantaneous values but cannot get load profile data. Below is the code in my method ( I then cal the method in the GXDLMS.client .example instead of the association view reading)
