The door and window alarms fromWyze Sense are a "wyze" choice. They come in a pack of four for under $20 from Wyze's website. Other companies charge that much or more for one sensor alone. And we’d guess you have more than one door or window to protect.
If Wyze doesn’t hit the mark for you, we’ve got sensors that work with smart home systems, standalone sensors, and more in our list below. Take your pick from the best door window sensors.
