Hi Henry,

I can confirm that the current Astrophysics experimental driver does work well in the Southern Hemisphere (Brisbane) in the following setup.
RPi4 running Ubuntu Mate 20.1 and using the current KStars Nightly build (now locked in). The mount is Astrophysics GTO1100 with the the CP4 controller and V13 firmware. The connection to the Pi is direct USB2 with no handbox.
If you have been trying some different configs I would suggest that you open the /.indi folder and delete the Astrophysics Experimental_config.xml file in order to start afresh.
Plug the mount into the RPi and powerup the mount. Start KStars and EKOS and start the profile that you have created for the mount (just for testing keep this simple and just use the mount and a CCD simulator.) Make sure that you have set your geographical co-ordinates in KStars settings and tick the "KStars updates the mount" box.
As has been mentioned before you could disable verbose logging if this interferes with the buttons (cold and warm)
Start the driver profile and open up the Astrophysics tab in the indi gui.
Do not unpark yet!
Go to the "unpark from" and set this to whatever your mount is current set at (Park 2 or Park 3 seem to work for me) make sure the mount is at the position that you set for "Park from"
Go to "Park To" and set whatever you normally park to (usually Park 3 for me).
At this point do not worry about where the mount appears on the KStars planetarium
In the indi gui click the cold start button.
Make sure that the "park to and from" values have not changed
Now click on unpark and track in the EKOS gui (or the indi gui)
Your mount should not move at all but should start to track
Now go to the Site Management tab in the indi driver and click on write data to save the parking co-ords
Now you should be able to do a test slew by clicking on a point relatively close to the current mount position be ready to stop the mount in case it flies off in the wrong direction
The mount should slew to the desired point on the planetarium.
Now go to the options tab in the indi mount gui and click "save config".
Now try parking but just check that the indi gui shows your desired parking position.
Press "park" in either the indi or EKOS tabs and the mount should park OK.
Try disconnecting the mount, close down the program then restart and connect again.
Your information regarding parking positions should now be retained for "park from" but is unlikely to hold for "Park to" so always remember to set this before you unpark and save the config but you will have to click on cold start in order to be able to unpark and continue as before.
If for any reason the cold/warm start buttons dont work just disconnect the mount then reconnect and select cold start to allow the unpark to work
It's not perfect but it is workable once you understand the limitations.
Previously the mount would always try to park as if it was in Kiribati for me in Brisbane and this made it always 4 hr out of sync so pretty frustrating. Wildi's hard work on this driver has given us a very workable solution and we thank him for all the hours he has put in!

BTW I tried the editing of the xml file as suggested above but both cold and warm buttons stopped working so I have stayed with the situation as described above.
Hopefully this makes sense and will get you on the right track.
