Sorry about the Angry response to your initial post. My tablet is so small and the screen so sensitive that sometimes when I am trying to scroll I hit buttons that I don't mean to hit.
I am new to chickens but I got the Omlet door. It is great! My coop is under cover so I use it on the timer mode as oppose to the light sensing mode. The flexibility of the Omlet is one of its biggest selling point as far as I'm concerned.
