I just got the auto door this summer. It's an Ador Door. It works great for letting the girls out in the mornings, but I have to close it manually at night because I live so far north that we still have blue skies at bedtime and the closing sensor isn't triggered. I can set it for a delayed opening, but not to close early. Once September rolls around this won't be a problem.
It is a bit tricky getting the girls to go to bed when the sun is still shining! I sometimes bribe them to go into the coop with raisins. I don't do it every night, but often enough that they stampede after me when I go in the coop in the evening just in case
