I had that problem with the camper chickens (that end up getting eaten by raccoons) and also sometimes additional guests like possums or skunks would enter the coop. In the end I always closed the coop at night manually and let the auto coop door open in the morning, that way I could sleep in in the summer. Next level of coolness would be a full coop monitor with non-chicken intruder detection. Alas, all my chickens have passed on by now so it'll remain a fantasy.
