Evnex integration won't load anymore in HA 2024.5

[xxxarmitagexxx]

Hi,

Recently the Evnex integration has been failing systematically to load in Home Assistant, currently 2024.5.1.

Looking at the logs, there is this error:

Traceback (most recent call last):
  File "/config/custom_components/evnex/__init__.py", line 164, in async_update_data

Any clue what the issue could be, it was working fine in the past.

From the error message it looks like the data has changed but I suspect its the validation library I'm using (pydantic) is finally updated.

I'm trying out a new pre-release now on HA 2024.5 - it won't be compatible with every component though (due to the way Python dependencies are resolved across components). Perhaps let me know if that works, otherwise I might need to see the debug logs before that validation error. https://github.com/hardbyte/ha-evnex/releases/tag/v0.6.0a2

Not sure if related, but the evnex HACS integration (0.6.0a2) hasn't been working for me for a couple of weeks now.

Just ran pip install evnex to make sure things were updated (HA 2024.5.5, Supervisor 2024.05.1). Rebooted, and getting errors in the log:

`Logger: homeassistant.setup Source: setup.py:271 First occurred: 09:01:04 (1 occurrences) Last logged: 09:01:04

Setup failed for custom integration 'evnex': Requirements for evnex not found: ['evnex>=0.4.1'].`

Unable to install package evnex>=0.4.1: ERROR: Cannot install evnex==0.4.1 because these package versions have conflicting dependencies. ERROR: ResolutionImpossible: for help visit https://pip.pypa.io/en/latest/topics/dependency-resolution/#dealing-with-dependency-conflicts`

Not sure where / how to resolve these dependency errors?

Follow up comment - is there any way to install this outside of HACS / through the terminal?

To try to resolve the dependency issue I uninstalled the Evnex integration. Now when trying to reinstall it through the GUI (+ Add Integration), I'm getting the error: "Config flow could not be loaded: 500 Internal Server Error Server got itself in trouble"

EDIT: finally managed to get the integration loaded - I think by uninstalling and reinstalling Pydantic from the terminal.

But now, despite entering my username (xxx@email.com + my evnex app account password), the devices fail to load thanks to this error: https://github.com/hardbyte/ha-evnex/issues/36

Still - closer than before a working integration!
