Time goes by and I don't have any more freetime to work on this project. I suggest you take a look at https://github.com/alexbelgium/hassio-addons/tree/master/nextcloud which is well maintained and up-to-date.
These add-ons can be installed in Home Assistant by configuring the following URL in the Hass.io panel:
