Here’s what I did to get this working.
Either hook up a monitor and kb to the Stellarmate or go to http://stellarmate.local:6080/vnc.html and replace stellaremate.local with the IP of your Stellarmate.
On the desktop you will see the software updater. Double click to run that.
After thats done go back to the desktop open a terminal window and run
sudo apt-get y install indi-bin
Finally, open http://stellarmate.local:8624 to open the web manager. Select your profile then go to drivers. Scroll to focusers and ensure ASI EAF is checked.
If you reboot the driver will load. You can see this in the web manager.
Works perfectly with ekos
