Aqara Door and Window Sensor T1 (Zigbee 3.0)

Secure your home and unlock a world of smart automation possibilities. The Aqara Door/Window Sensor T1 is an incredibly compact wireless magnetic contact sensor that constantly monitors whether your windows, doors, or even safe cabinets are open or closed.

Security and Smart Scenarios

The moment a door or window is unexpectedly opened (when the magnet separates from the sensor body by more than 22 mm), it instantly sends a push notification to your smartphone. Beyond security, this sensor serves as the foundational trigger for everyday smart home scenes:

• Lighting: Program the lights in your closet, pantry, or garage to automatically turn on the second you open the door.
• HVAC Control: Link the sensor to your smart thermostat or radiator valves. If you open a window to ventilate the room, the heating will automatically suspend to prevent energy waste.
• Intruder Alarm: Pair it with your central hub to create a robust security system that triggers a loud siren and flashes the lights red upon unauthorized entry.

The New T1 Upgrades & Specs

This improved T1 generation introduces support for the modern, lightning-fast Zigbee 3.0 protocol, significantly increasing connection stability and energy efficiency. It also fully supports OTA (Over-The-Air) firmware updates. When paired with a compatible Aqara Hub (such as the M2 or M3), the sensor unlocks seamless integration into Apple HomeKit, Google Home, and full support for the Matter ecosystem.

• Dimensions: Ultra-slim profile measuring just 41 × 22 × 11 mm.
• Battery: Powered by a single CR1632 coin cell (extremely low energy consumption guarantees an average lifespan of up to 2 years).
• Installation: Tool-free mounting. Both pieces simply adhere to your door and frame using the included industrial-strength double-sided tape.
