Functionality with Kamstrup DK-8660 electrical meter
Closed this issue · 3 comments
I was going to start with a similar project as my first project in many years, so I started with a test connection with Arduino to see what I got out of the serial port. I use a HAN port with RJ12 and inverts the signal.
There is a lot of conflicting information about port speed, but I got 2400 baud to work. I expected a list corresponding to your example list, but got the following according to appendix image (char dump) and list below (int dump).
Am I lost or may the power network owner have set the wrong parameters for my electrical meter?
It's a very small power network owner and I am the first customer with RJ12 adapter?

It seems you have A-XDR and it reads out correct. As you have to use 2400 baud you might have an older version but I can tell that the initial data is correct as it starts with 126 (0x7e).
Here is an explanation of the meaning of it: https://github.com/aviborg/swedishP1/blob/main/data/aidon20201108_112447.txt your dump seems to be very similar if you convert it to hex.
If you use my ESP-code what does it show at http://emeter/data.json ?
Thanks so much for your help. Really appreciate it.
Then I understand better how the information from the meter is intended.
Then I can try the next step of testing your code and we will see what results it gives in data.json.
