We failed to set the rtc clock of meter using Gurux UI, may be due to some limitation of ms in timing of the meter ,
Is there is any Gurux python library is available so that i can try using the script?

Also i want to go the all the configuration of meter using Gurux python library, Can you help for the same.

Hi,

I want SImulator to act same meter

Below is the setup used
1. Created .xml file from meter.
2. Using Manufacturer: Indian Standard, Authentication: PC

Hello, please help me,

When I try to load my collectionObject file using the method, GXDLMSObjectCollection.load from the gurux library for python, I get the error: can only concatenate str (not "GXDLMSData") to str.

The file is saved in .xml format and the structure seems correct. Below is an extract from my code:

Hi

I want to connect Wasion iMeter318 using a serial port what is the configuration to connect it?

How to add the kW, kVA in scalar units as there is no value defined in the DLMS blue book.

How is DLMS meter reading possible using MQTT protocol, what is the advantage of using MQTT over dlms wrapper to read meters?

Newbie here, "Hello"

In HDLC Mode protocol disconnect from meter looks something like this:

HDLC Flag: 7E Frame format: A0 Frame length: 07 Dest and Source addresses: 0303 Control field: 53 HCS: 80D7
HDLC Info.: FCS: Flag: 7E
SEND: 7E A0 07 03 03 53 80 D7 7E
RECV: 7E A0 20 03 03 73 F0 2E 81 80 14 05 02 00 F8 06
RECV: 02 00 F8 07 04 00 00 00 01 08 04 00 00 00 01 58
RECV: 71 7E

How do you protocol disconnect in IP mode from meter? (not TCP disconnect)

Thxs,

Hi!

If encryption and authentication is used in DLMS, we need an encryption key (EK) and authentication key (AK).

The authentication tag is created using the AES-GCM algorithm, using the EK. From my point of view, the packet is then already authenticated by the owner of the EK because AES-GCM provides authenticated encryption.

I wonder, what is the purpose of adding an AK to the additional data of the crypto protection?

Thanks for any comments.

Hi Mikko,

In single action schedule object, we have to set the execution time array attribute.

In that, Can you please provide an understanding of the time interval?

If I set the following interval into the meter, Then meter sends data on every 15 min or
every 15 min of an hour.

*-*-* *:15:00

And do we need to set multiple interval to get data on every 15 min like,
*-*-* *:00:00
*-*-* *:15:00
*-*-* *:30:00
*-*-* *:45:00

Thank you in advance.

Regards,
Bhaumik
