@David3610 oh my god THAT’S why my guests keep dong this!!!
Thank you so much for solving this mystery! We have these dotted throughout our place to highlight tripping hazards in the dark, so people don’t trip on doorway tracks as they make their way to the bathroom at night. I found it so strange that people weren’t just turning them off, they were unplugging them, covering them, putting them in drawers.... my god, they must think the sensor on the front is a spy camera!!!
Thank you so much for pointing this out. I’m now going to label them with a sticker so people know what they are.... I never would have thought this was the reason, but it makes so much sense now that you’ve pointed this out.
