I have a chickenguard extreme and I love it. I only use it to shut the door after dark, I prefer to open it, or not open it myself. I do not want the chickens getting used to a schedule and bawking for me to let them out. So far so good.

Sounds fun, I am automating the easy way, with my Amex card... I have a auto door that closes using a light meter and a smart wifi enabled switch for lights and water heater. I have strong wi-fi in the coop area I will be adding cameras so I can peek in on everything from my phone:)
