20CHF for night is for campers - there is a sign, but it doesn't include cars. It is free for cars from 7pm-7am (you can pay during the day by easy park app). We were amazed by the toilet - it was heated, warm, with soap and very well maintained. There is no sign prohibiting camping. The lights are on during the night so you feel quite safe. Be cautious on your way up there - very narrow road.
