WiFi Wall Switches/Apps for Millisecond Control of Motorized Blinds

Hello everyone! I wanted to ask if you know of any wall switches (double) or apps for controlling blinds (or shutters) via WiFi that allow programming of the motor run time on a millisecond level. I have 2 internal motorized blinds fitted which only have the ability to raise and lower (they do not have a function to rotate the slats by a set angle, the slats only rotate when the blind starts to wander up or down). I have programmed them in the app to lower and raise at set times, but I would also like to be able to control the rotation of the slats so that they let in more or less light. Unfortunately, the app allows the least amount of motor time at 1 sec - far too long for the louvre to rotate so that it is horizontal (it rotates 180% and the louvre starts to wander upwards). I estimate that 0.5 sec of operation is enough to get the louvre horizontal and so I am looking for other apps or buttons (double, in one flush mounted box) - do you know of any?
Greetings and all the best for 2024!

What is the app and what exterior roller shutter controller. Is it possible to replace the controller

I'm using Smart Life and Google Home apps, and I have a T522 controller on the wall (LR TUYA WiFi series: https://houseiq.pl/pl/p/Sterownik-2-rolet-zaslon-WiFi-seria-LR-TUYA/1633). The controller is due for replacement anyway - it broke after I turned off the home WiFi for a trip, then wouldn't connect to the WiFi anymore, and after trying to reset it stopped working altogether. I'm in the middle of a complaint - unless you can recommend something for more precise control
