Editor's Pick: If you have a side door, storage room, or a metal gate to your yard and often worry about forgetting to close it or someone tampering with it, just stick one of these sensors on and you'll get alerts on your phone. With IP66 water and dust resistance, it holds up through wind, sun, rain, and snow, and you don't need to buy a separate hub since it connects via Amazon Sidewalk. Installation is easy too—just peel off the adhesive backing and stick it on the door frame.
