Integration of Viessmann Aquahome 20 SMART with Home Assistant - how to read the data?

Hi,

have any of you tried to access the data from the Viessmann Aquahome 20 SMART water softening station?
I am thinking of buying such a unit, but would like to have info on water consumption and the amount of salt on the HA.
The only thing I can read is that there is an iQUA application where we will see these parameters, but this does not suit me because I will not install an application on my phone for each device. I need this for the Home Assistant. Viessmann provides a platform for developers https://developer.viessmann.com/, but I have not found there any information about the possibility of reading data from the Viessmann Aquahome.

I would be grateful for any information.

Here you have the integration. You add via HACS

Hi. I have a problem installing this addon in a Homeassistant set up on an RPi4. The description says to install this addon in the config folder. I am not advanced enough in RPi to find this folder. I've tried installing via the repositories in the shop but I keep getting the response that this repository is not correct.
