A couple of months ago I wrote a Python library and custom home assistant integration for Evnex chargers.
The evnex Python library can be used to communicate with the evnex api from a Python program or script. It can be installed using:
pip install evnex
The Home Assistant integration can be installed from the Home Assistant Community Store, or manually using the source code from https://github.com/hardbyte/ha-evnex
Once authenticated, the integration creates a device in Home Assistant for any chargers you have access to. Each charger exposes a bunch of sensor data, and a switch to control starting and pausing of charging.
Some of the data exposed to Home Assistant can be seen in the screenshot:
