async def _home(self):

Uses await self._not_busy_sig.wait() to determine when to set the position.

This is less critical than ensuring that the set_position behavior is correct, as homing is usually only done by human interaction that is not rapidly polling the busy state, but still.

There is not an explicit message for "home completed" as there is for APT, so some additional care must be taken here... shouldn't be that hard, but yeah.
