Wanted to know if this is out there yet...have automated door equipment that will go in run, looking the activate door based on light (I.e. dark, door shuts, light it opens) but would like to put a motion sensor that stops door from opening if movement detected (possible predetor). Is there something like that availible? Wanted to do timer but light shifts drastically so might need constant adjustments. The coop is bear proof so would like chickens to remain in the coop until I can clear what tripped motion sensors...
If you're meaning you'd like an automatic door opener that can open the door based on when it gets light and close it when it gets dark, yep, that exists The ChickenGuard door opener has this feature. I've used it myself and it works well. It doesn't have a motion sensor though - not sure if that's something you might be able to add on your own in some way or not.
