Hi there Thomas,
Generally new integrations are rarely and seldom put into Home Assistant Core first, as you are asking for when putting in a Feature request here. The usual path is someone builds a custom integration that can be use with HA. It is then used and tweaked by the author, and that is then in a form that could be loaded into HA core.
I suggest looking for some existing code elsewhere, this could be a thing somewhere. You will also need to find someone to help you code and that would be a good place to look as well.
I wish you luck.
