I have an automatic chicken coop door from the company Run-Chicken. It is one of the most brilliantly designed products I've ever owned. It has an app for setting up the opening and closing rules, which can be rather sophisticated, based on both time and light conditions. The device itself has no WIFI, bluetooth, or a radio of any kind . To program the device, you push a button to put it into a programming mode, then…
Really clever piece of engineering on the programming mode for sure.
