Door and Window Sensors

Browse door and window sensors with sourced platform, power, and sensor-type information.

Check the hub before the sensor

Door and window sensors may use Matter over Thread, Zigbee, a brand-specific radio, or direct Wi-Fi. The protocol determines which hub or controller is required and which smart home platforms can receive alerts or run automations.

Required controller

Matter over Thread needs a compatible Matter controller and Thread border router. Zigbee and brand-specific sensors usually need a matching hub, often sold separately.

Platform support

Check the exact listing for Apple Home, Alexa, Google Home, or Samsung SmartThings support. A supported protocol does not guarantee every feature in every platform.

Fit and power

Measure the gap between the sensor and magnet, then confirm the mounting method and replacement battery. Door frames and battery access can rule out an otherwise compatible model.
