A few more years later...
I'm using Indigosky on a Raspberry Pi to control my XT5 and mount. https://www.indigo-astronomy.org/indigo-sky.html
Have it paired to Indigo D1 running on my Mac https://www.cloudmakers.eu/d1/
Works well and can control the camera.
Couldn't get Kstars/Ekos to work reliably with my XT3 and not at all with my XT5.
