After reverse engineering the API myself I found out that there is already a Python libary wrapping the Alfen API. https://gitlab.com/LordGaav/alfen-eve/-/tree/develop/alfeneve

If you do not have HACS installed yet visit https://hacs.xyz for installation instructions. In HACS go to the Integrations section hit the big + at the bottom right and search for Alfen Wallbox.
Clone or copy this repository and copy the folder 'custom_components/alfen_wallbox' into '/custom_components/alfen_wallbox'
Once installed the Alfen Wallbox integration can be configured via the Home Assistant integration interface where you can enter the IP address of the device.
The wallbox can be added to the Home Assistant Energy Dashboard using the _meter_reading sensor.
