Let me unconfuse you:
I thought, that the calibration detects itself maximum Close.
So my purpose with the chair was to tell the rollo, what`s maximum.
I tried, but when I took away the chair and close again the rolle, it went down to bottom and was 100% dark.
So, I don`t understand, why to make a auto calibration…..
I didn`t think about the screws IN the shutter. Have to look, if I will find them.
@coldbringer: My idea was to say 100% close means stop 20 cm above bottom. Use the XX% icon at a mobile isn`t as comfortable as just to swipe right or left. 😉
I´ll look for the screws 😉
