Many thanks for the amazing s/w -- on of the best and nicest written OSS i've seen.

(Apologies in advance if this has been asked earlier; didn't find it anywhere) Do you have any documents on how to contribute?

Hi,

I am having an issue. When I put the COM port in source setting the program still cant read the data instead of just show same as not changing the COM port.

Hello, please, I have a meter at my disposal that I want to connect to via the serial port, but I don't know the server address. Is there a way for me to automatically detect the server address of the meter, or is there another way I can connect to the meter without the server address?

Thank you in advance for your response.

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?

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?
