I did not practice a lot of tests.
I have pluged my EFW on the RPI3 (that run Ubuntu Mate) and launch Kstars then Ekos and finaly starts INDI in local mode.
For testing I choose the devieces as folow :
Mount : Telescope Simulator
CCD : CCD Simulator
Filter : ASI Wheel
The logs that returns indi is in my previous message.
May be there is a log somhere else but i dont know where. If so, let me know where to look
Sorry not to be more accurate in my explanations and I hope my english is clear enough for you to understand (i m french)
