[🐛]: Using min_example.py results in “error_permission_denied”

[Sweenylein]

What is the current behavior?

Today, I used an example file min_example.py with the token from the linked documentation (6eb6f069523055a339d71e5b1f6c88cc).
This error message appears: Error during getting plant list (Code: 10011, Message: error_permission_denied).

I then used a token that I retrieved from my Growatt web system. I use a MIC inverter. There, a different error message is displayed: “Found 0 plants Unexpected error: list index out of range.” That can't be right either.

What is the expected behavior?

Retrieving data from the inverter

How can we reproduce the issue?

Using 6eb6f069523055a339d71e5b1f6c88cc in min_example.py

What is the proposed solution?

Hi @Sweenylein ,
I just stumbled about this issue you created.
I'm not a maintainer here, but just a developer interrested in growatt API.
Still, I would like to assist a little:

The test token is only to be used with the test server. From the linked docs, this is test.growatt.com
Unfortunately, you cannot set the server url as a parameter when using V1 api. But you can work around this issue by using

    api = growattServer.OpenApiV1(token=api_token)
    api.api_url = "https://test.growatt.com/v1/"  # Use test server

You will be able to login and authenticate, but the example still does not work as no devices are assigned to plant [0]

output:
Plants: Found 997 plants
<end of output>

Although this does not really help soving your issue with your own plant/device, maybe this helps others investigating their issues with the test server

This is probably the same issue you are having: home-assistant/core#155931
