Having not seen any photos of setup of the coop, I would advise that if you are going to use an automated door, the opening to the coop should not have as any ledge that could be confused as a roost. With my original coop, my pullets would roost in the doorway to the coop at the top of the ramp and not go in. This was being off the ground to them.
When I built our new coop I wanted to deploy an automated door. That was one of the reasons I built a front porch for them. I use the Ador and I love it. No one has ever been locked out. The last call feature assures me of that. I also oriented the coop door towards the setting sun in order to give them the most time out on the sensor. It is truly dark when the last call operates and let's any straggler in.
Here is my porch.
