Functional problem

[GevaudanBeast]

Hello QuickSander,

I am encountering a problem :
When I try to change the position of one of my roller shutters, the first press on the button (to open or close it completely) in the Home app produces no effect (the encoder wheel appears at the top right of the button ), I then have to press again to "cancel" my first request and start again for it to finally work. I don't have this problem, if I do a long press and set a specific percentage.

Here's a result from my logs that might be useful (but is irrelevant to when I'm using a roller shutter):

A snippet of my config file:

            },

            "invertPosition": true,

        },

Thank for your help !
