Homeassistant as a Wireguard client

I have an rpi running wireguard. Now I want to setup my hass installation to connect as a client to this wireguard.

I am aware of (and using in other places) the wirequard add-on from Frenck, but this is for running a wireguard server, not a client (as far as I know).

Anyone any pointers on how to do this ? Thanks !

Works great!

This is an old post, but if anybody stumbles across this searching for a similar solution, I just made a tutorial for this: Integrate Home Assistant Green into a wireguard VPN (client without port forwarding)
