Window & Door Sensors
Entry Monitoring For Smarter Security & Everyday Automation
Window and door sensors use magnetic or contact-based detection to determine whether a door, window, cabinet, or other enclosure is open or closed.
These sensors integrate with your smart home platform to trigger lights, adjust climate settings, send notifications, or activate security routines based on real-time activity. Their compact design, low power usage, and flexible mounting options make them useful for both home security and everyday convenience.
Real-Time Open & Close Detection
Sensors provide immediate status updates to your smart home system, allowing automations or alerts to trigger as soon as a door or window is opened.
Compact & Discreet Installation
Most sensors use small magnetic contacts that mount easily on frames, casings, and sliding tracks, making them suitable for nearly any style of door or window.
Automation Support Across Smart Platforms
Sensors can trigger lighting, adjust thermostats, pause HVAC systems, or start security routines based on whether an entry point has been opened or remains closed.
Battery-Efficient Design
Low-power radios such as Zigbee, Thread, and Z-Wave allow most sensors to run for years on a single battery, reducing maintenance needs across your home.
Flexible Applications Beyond Doors & Windows
These sensors can also monitor cabinets, safes, refrigerators, or interior doors to support custom routines, safety monitoring, or parental controls.

Frequently Asked Questions
How do window and door sensors work?
Most sensors use a magnetic contact system. When the magnet and sensor body separate, the sensor reports an “open” state to your smart home platform.
What smart home platforms support these sensors?
Support varies by model, but many sensors work with Home Assistant, SmartThings, Alexa, Google Home, Apple Home, and Matter-enabled ecosystems.
Do window and door sensors require a hub?
Zigbee, Thread, and Z-Wave models require a compatible hub or coordinator. Wi-Fi and Matter-over-Wi-Fi sensors may connect directly without additional hardware.
Can these sensors improve home security?
Yes. They can alert you when doors or windows open unexpectedly, and they can work with other devices like cameras or sirens to enhance a home security setup.
Where else can I use these sensors besides doors and windows?
They are useful on cabinets, drawers, gates, mailboxes, and appliances. Many users apply them to routines that track access or detect unusual activity.
