Hi, my wall where is a sonoff installed is a little crooked. So after installation back part of sonoff is little wavy. When i mount front panel, sometimes i have to push hardly. I think there are a little gap between touch sensor and front panel. Can i insert something between sensor and glass front panel to better reactions? Thank you
Better to move panel forward with the spacer so front fits well.
Also clean behind glass and on sensor with a dry cloth, blow away any dust.
