I am ready to buy an automatic door but there are so many to choose from and many of the reviews I've read are from 2018 so wondering if there are 2019/20 models that I should look at with improvements. Our coop is enclosed in a very predator proofed run but I still would like to close it up for the nights. I'd like it to be WIFI and battery enabled since it doesn't get that much sun under the big oak. I would also love to have a feature where it could open again if one of the hens didn't get in on time. From what I have read they start to know and if the sun is down they're already in there coop. Thanks for any advice.
