Looks like there was a fix to get the reverse motor direction button to work with the ZWO EAF but it might not have made it to the Astroberry repos ? I think the current version is 3.1.9
Looks like not a lot of interest in this, however just in case!
To get the reverse motion working I had to recompile from github Indi, Indi-lib and the 3rd party driver. Compiling the 3rd party driver alone did not solve the issue.
Oh, I thought there were some other sources for EAF driver discussed.
If recompiling (from github) libindi and indi-asi driver works, it means that the change was introduced to libindi, not indi-driver itself.
It will be pushed to astroberry repository along libindi 1.8.6
