If anyone wants to know, these work for me:
The ASIAIR USB to RS232 connects to the iOptron RS232 cable which plugs into the RS232 port on the mount.
In SkySafari > settings > setup > equipment selection > scope type; select: iOptron CEM/iEQ Pro/AZ Mount Pro
In mount type select: Equatorial GoTo (German)
✅Connect via WiFi
✅Auto detect SkyFi
SkyFi Name: SkyFi
