Since the park position requires being able to move to user definable Hour Angle/declination or Altitude/azimuth position, and ASIAIR has only so far be able to GOTO a Right Ascension/declination position, you will need to wait until that is available, before home is available (unless it is available in the mount themselves, in which case ZWO could just use mount commands).
Yeah, it is a 5-minute addition, and even Meeus' book has ready equations, but ZWO has resisted implementing a GOTO to alt-az coordinates, or fixed hour angles, for at least three years since requests started appearing.
