Opening a window on a curtain switch on percentage

I have a chain motor to open a window, motor with 3 wires, neutral, open and close. Added a Loratap Curtain Switch which shows up in HA as a TuYa TS130F, calibration done, set to 15 seconds running time. So far so good, no I want to ste the window to half way open so shift the bar to 50%, windows opens all the way…
Am I doing something wrong or is ther still something else I need to set/change to get this percentage to work properly?

Reagrds, Fantic.


I have exactly the same problem, did you get it solved?
