ZigBee Smart Life how to consider inertia

I have a pretty long large and heavy roller shutter in alluminium. The engine is a bit undersized and as a result the time to go down is 30 seconds while the time to go up is 32 seconds.
I have a moesgo switch ZigBee + RF associated to home assistant through smart life.

If the travel is complete either way all is good. If I open or close partially the shutter, it starts gaining few cm every time so that the shutter is not completely open.

I think this is due to the higher inertia in opening versus closing.

Is there any parameter to correct this?
