Hello! I don't know how far your coop is from the house or the orientation with regard to your house, but this works for me on a super tight budget. I attached a rope to the top of the pop hole door and through a series of eye hooks mounted on the coop, the garage, and the house. The rope goes from the coop door, over the yard and right into the window right by my bed. In the morning, I just have to crack the window and pull the rope. Voila! It works regardless of whether the electricity goes out, and the parts are less likely to 'surprise-fatigue'. With the manual approach, you never have to worry that it didn't open and your chickies might be roasting inside on a hot day. It doesn't work so well when I'm not actually home though... Cheers!
