Still have this problem.
Indi built from git on RPI4. Running kstars either on the RPI or on windows. GEM45 runnin the iOptron v3 driver.
When the GEM45 slews, it will slew to the correct location and stop, but indi/ekos does not detect that the scope has stopped. Status in ekos is that the scope is still slewing even if has stopped. The scope will automatically start tracking if I press the red stop button in ekso scope controls.
I have tried to delete the .indi folder and set up everything from scratch, but no solution.
Same behaviour with handset attached and without.

Ideas anyone?
