Hello! I am very inspired by your project and started my own, unfortunately, there is a problem with the registers for me. How did you retrieve those register? I found this document from huawei :

https://support.huawei.com/view/PdfRead/EDOC1100050690/SUPE_DOC/6001/document.pdf

but none of the registers listed there are the same as yours. Moreover, I can't seem to find anywhere on the datasheet that you can use ModBus TCP with a sun2000. Only RS485 (Modbus RTU) is available for communication. Would it be possible to give me a clearer idea on how you did this?

thanks in advance

The version I'm using is Interface Definitions (V3.0) for the Modbus registers. Also filled some of the blanks with the scanner files from the project. However, you can change the Huawei.py file to suit your needs, or even make a new one

Could be that your inverter doesn't include tcp, Huawei has a bunch of different versions. The residential models seem to do. Are you using a commercial one?

Think it should be able to change the tcp calls to rtf. The library does both

Hi basking-in-the-sun2000
Thanks for your project.
I'm trying to execute in Visual Code for Windows and I get the following error:
PS C:\Users\nocturno\Dropbox\Micropic\Proyectos\solar-logger-master> & C:/Python39/python.exe c:/Users/nocturno/Dropbox/Micropic/Proyectos/solar-logger-master/main.py

File "c:\Users\nocturno\Dropbox\Micropic\Proyectos\solar-logger-master\config.py", line 33, in
latitude = lat
NameError: name 'lat' is not defined

I have defined my latitude and longitude in data_sources.json but I get the same error.
Can you help me?

Thanks you very much

[basking-in-the-sun2000]

There are a series values you need to replace in the config.py file to reflect your site. Among these are the latitude and longitude (to actual numbers for your location). The data_sources.json is just the grafana definition for your databases.

Try reading the README.md and setting_up.md. Let me know if these need further work to make them easier to understand.

I got it!!!!

Thanks you very much for your help

[basking-in-the-sun2000]

Great, glad you got it working

The colors might be off, since I set the thresholds according to my system levels. You might want to take a look at them, in the panels. Will try to take a look if these can be set as grafana variables, to make it easier if you upgrade the dashboards.

My MEW-01?
I don't see any device on my Supla account.

Thanks

[bdkacz]

Do You add your MEW-01 into supla ? Do You see it in supla app ?

[nocturno66]

I don't have a MEW-01; I have a Raspberry Pi with this solar-logger firmware.
In Supla, I have looked for new devices and did not find any.
Thanks

[bdkacz]

Supła integration is for reading data from this device https://supla.zamel.com/en/product/mew-01/ If You don't have this device You can skip supła configuration

[nocturno66]

Ah, ok, I didn't know. I believed that the integration was with the Pi.
Thank you

[ScApi]

I'm trying to properly configure Supla part but no matter what I try most of the times i get
supla error: Invalid base64-encoded string: number of data characters (5) cannot be 1 more than a multiple of 4
It's probably something trivial but I'm missing it.

Edit: I've managed to get it sorted out (need to authorize token) but I don't see any movement in dashboard.
GRID stays at 0

[basking-in-the-sun2000]

Sorry, I really never looked into the supla code, since @bdkacz provided it.
