Yes, ASCOM/EQMOD does it so there must be a way on INDI.
I hope we can get this feature because unfortunately to me this is a deal breaker, I'm in a quiet area and the HEQ5 is way too noisy at max speed to use during the night with my neighbors sleeping all around.
Jasem, let me know if I can do something to help you with that. I'll be glad to beta-test the feature if needed.
