Because it was light very early in the morning I had been letting them out at 6 a.m. but a fox snaffled one of my girls so I put the timer back to 9 a.m. Also I want my chickens to lay their eggs in the nest boxes not all over the farmyard and have to go hunting them down.
My coop is under a tree so the sensor shuts the door before they have gone to bed, especially when the tree is in full leaf, so I still have to go out there to open it to let the stop outs to bed. Consequently for me the sensor was not an option and didn't make life easier I tried it and was not happy with it, that is why I bought a door that gave me the option to be flexible. I want the options of being able to do, what I want to do, not be dictated to by a company that thinks it knows better, when said company does not know every ones set up, so IMO said company is losing trade to those that want an option and are not being given it.
