Exception when launching venv/bin/python -m growatt <user> <password>

[achimera]

Hi,
I've executed all steps but when launching to connect to my growatt server, I receive the following exception. User and password are correct.

``_Traceback (most recent call last):
File "/Users/achimera/dev/growatt_api_client/growatt/init.py", line 71, in login
result = self._back_success_response(response)
File "/Users/achimera/dev/growatt_api_client/growatt/init.py", line 147, in _back_success_response
raise GrowattApiError()
growatt.GrowattApiError

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/runpy.py", line 193, in _run_module_as_main

raise LoginError``

This happens when the Growatt API returns a valid JSON response indicating that the login attempt was not succesful. This usually happens when the username or password is incorrect. Please check your credentials and put them between 'single quotes' to prevent your shell from messing up the arguments.

Hi Sjoerd,
yes, single quoting the user and the password was the trick! Now I'm able to access. Thanks!
