We’ve been having trouble with rodents (I assume squirrels) in the crawl spaces on our second floor. I decided to stick a PIR sensor on the door to see if I could catch any movement, and sure enough, a bunch of movement around 1 AM this morning. (Correction, it was a possum, which makes sense in hindsight as they’re nocturnal).
@jongranrose @early_riser FYI, vampires don’t trigger motion sensors. So if you do it and the sensor doesn’t go off, you probably have vampires.
