Hello, I've tried to connect a botton switch to know if the door is open or closed, i've added it through the gpio panel and set it up to read, altough it always shows as off, what is the right way to connect the button to RPI and to this wonderful software? thanks in advance

HI, You must add 3.3V to GPIO then You have HIGH state.
