Aqara Zigbee Door & Window Sensor 3-Pack – Wireless Mini Contact Sensor for HomeKit, Alexa, IFTTT

Meet the Aqara Zigbee Door and Window Sensor 3-Pack, a compact wireless contact sensor designed to keep you informed about door and window activity. Paired with an Aqara Hub, this trio brings smart awareness to multiple entry points without adding visual clutter. The small main unit and its magnet work together to detect openings, delivering timely status updates to your phone and enabling automations across your Aqara ecosystem.

Optimized for real‑world use, the sensors blend into frames and furniture while offering dependable performance. A stable Zigbee link to the hub, together with compatible 2.4GHz (or 2.4/5GHz for certain hubs) Wi‑Fi setups, helps ensure notifications arrive when you need them. The setup focuses on practical reliability: keep the main unit within a short distance of the accessory, keep the hub and router on the same LAN, and position components to minimize gaps that could affect sensing.

What you gain goes beyond simple status checks. When a door or window moves, you can trigger local alarms or coordinate actions with other Aqara devices to create custom scenes—such as lighting or climate responses—based on whether a door is open or closed. The sensor supports hands-free control through popular ecosystems, including Apple HomeKit and Amazon Alexa, and it can integrate into broader automation routines via IFTTT. While these capabilities offer a path to more seamless living, they are options to explore rather than guarantees.

Key benefits at a glance

• Compact, discreet design with a main unit about 1.61 × 0.87 × 0.43 inches and a magnet around 0.79 × 0.39 × 0.39 inches for versatile placement on doors, windows, drawers, or cabinets.
• Wireless, battery-powered operation paired with a reliable Zigbee connection to an Aqara Hub for timely alerts and automations.
• Proximity-friendly setup that accommodates most doors and windows with a permissible gap up to 0.86 inches, plus guidance to maintain a stable link (keep main unit within a short distance of the accessory).
• Hands-free control through Apple HomeKit and Amazon Alexa; integrates into IFTTT workflows for broader automation options.
• Three-pack convenience to cover multiple entry points, ideal for front doors, back doors, and interior cabinets or drawers.

Practical use scenarios

• Front and back doors: receive timely status updates when a entry point is accessed.
• Nursery or kid zones: monitor doors to stay ahead of early activity without constant checking.
• Cabinets and drawers: supervise access to valuables or tools with automated cues.

Compatibility notes: An Aqara Hub is required for operation. This sensor is designed to work within Aqara’s Zigbee ecosystem and may not be compatible with third-party hubs. If you’re setting up, ensure your hub is within range of the router and that both are on the same LAN. Some hubs support specific Wi‑Fi bands, and SmartThings is not supported for this particular setup. The 0.86 inch gap specification helps define suitability for typical door/window configurations.
