Hi all,
I have a question.
I am studying how to sync clock on a meter and I stumbled upon this definition:
"The Deviation and the Clock Status may be defined or may be left undefined:"
Case A:deviaition not specified, clock status not specified
CAse B: deviation not specified, clock status with DST set to 80 or 00
CAse C: deviation is set to deviation from local time to UTC, clock status with DST bit 00.
My question are:
1.When we want to sync meter date, meter has to support all 3 methods?

I try to read register with address 1.8.0 because according my research on internet 1.1.1.8.0.255 refers to total active import energy.

But according to returned message from Gurux and 62056-61, 1.8.0 is said to be Sum Li Active power+ (QI+QIV) Time integral 1 Rate 0.

Do these two description mean the same or if not what causes the difference?

DLMS connection is success in DLMS Gurux Explorer with US mode on TCP Wrapper and below is the TX and RX log.

hi
I need to connect my meter with IEC 62056-31 protocol

Part 31:
Use of local area networks on twisted pair with
carrier signalling

it possible ?

I'm running a research project where we want to collect some readings from a smart meter that produces a public-key signature. We don't need to actually use the meter in any real deployment - it's purely a proof-of-concept experiment for a research project in cryptography. All we need to do is hook it up in a lab, and grab some readings from it on a computer.

Here is an example of hexadecimal data received from the HAN port of a Kaifa MA304H4PSE:

7e a0 9a 01 00 01 10 12 10 e6 e7 00 0f 40 00 00 00 09 0c 07 e7 0a 14 05 12 3a 0f ff ff c4 00 02 12 09 07 4b 46 4d 5f 30 30 31 09 10 37 33 34 30 31 35 37 30 33 30 39 30 34 30 34 35 09 07 4d 41 33 30 34 48 34 06 00 00 01 a9 06 00 00 00 00 06 00 00 00 00 06 00 00 00 04 06 00 00 00 61 06 00 00 01 ac 06 00 00 05 c4 06 00 00 08 fa 06 00 00 08 fe 06 00 00 09 0f 09 0c 07 e7 0a 14 05 12 3a 0f ff ff c4 00 06 00 07 4b b5 06 00 00 00 00 06 00 00 64 3c 06 00 02 6e f6 4b 0b 7e

Is there a Gurux.DLMS package for OpenWRT in the .ipk installation package?
If not, how can I install the libraries on OpenWRT myself?

I am new to to smart meters, I was recently checking out a smart meter system, the gateway is a esp8266 which communicates to the data collector over mqtt with some hex format. other meters connects to the gateway meter with some sort of rf mesh NAN with 32 bit meter address similar to ipv4. the data collector publish to the topic with the name of the grid id of the gateway meter.

Hello guys, im a total newbie on the subject of smart meters and DLMS

would anyone be willing to spend some time on a chat, explaining to me the basics of how to get started? Id be glad to pay for the effort

can we write the disconnection control ones meter has connected. Can you tell how ?
