Only once, then I changed my door temperately to a timer while I finished testing the Raspberry Pi 3 code which adjusts the open close time by sunrise and dusk every day automagicly.

I had a photocell on my door and a thunderstorm came up and the door closed! If I had to use a commercial door IMHO a timer is better because you can set it to close at dusk and every chicken will be in by then.
