## Overview

The Aqara Door and Window Sensor T1 is a compact, wireless contact sensor designed for smart home security and automation. Operating on Zigbee 3.0, it requires the Aqara Hub and a 2.4GHz Wi-Fi connection to deliver instant open/close alerts and enable automation. Compatible with Apple HomeKit, Alexa, and IFTTT, it offers hands-free voice control and fits a variety of entry points with a simple adhesive installation. Its 400-inch reliable range and included lithium battery make it a practical addition to any connected home.

## Description

The Aqara Door and Window Sensor T1 detects the open and close state of doors or windows through the distance between the sensor unit and the magnet. It consumes a minimal amount of energy. No tools are required, just stick it to the desired place and use it in a dozen of possible use cases.

Review: Dead on Arrival - I thought I was going to find a zigbee door sensor that was more reliable than the IKEA parasoll but found one even worse. Showed up with a dead battery, but even after replacing the battery I didn’t get more than the brief flash at install. Pairing does not work. Proximity does not work.
Review: Stopped working after 2 months - Died after 2 months. New batteries did nothing.

## Features

- Note: Requires an Aqara Hub (sold separately) and a secure 2.4GHz Wi-Fi connection (Hub M2 also supports Ethernet). Not compatible with hubs from other brands.
- Connection Range: For stable performance, keep the sensor within 400 inches of the Aqara Zigbee Hub, and ensure the hub is within the same distance from your Wi-Fi router. Both must be on the same local network.
- Security Alerts & Automation: Get instant alerts on your phone and trigger alarms on the Aqara Hub if a door or window opens unexpectedly. Easily automate other Aqara devices based on door or window status for enhanced home security.
- Wide Compatibility: Works with most doors, windows, drawers, and cabinets with gaps up to 0.86 inch. Sensor size: 1.61×0.87×0.43 in; Magnet size: 0.79×0.39×0.39 in. Ensure installation surfaces are flat and adhesive-friendly.
- Hands-Free Voice Control: Compatible with Apple HomeKit, Alexa for a hands-free experience.- no need to go downstairs or pick up your phone again. You'll always know whether your home door is opening or closing. (Not compatible with SmartThings.)

### ⭐ Dead on Arrival
*by S***. on September 6, 2025*

I thought I was going to find a zigbee door sensor that was more reliable than the IKEA parasoll but found one even worse. Showed up with a dead battery, but even after replacing the battery I didn’t get more than the brief flash at install. Pairing does not work. Proximity does not work.

Died after 2 months. New batteries did nothing.

### ⭐⭐⭐⭐⭐ Review
*by J***E on June 9, 2025*

-Je ne voulais pas particulièrement d'aqara (pour ne pas ajouter une nouvelle marque à mon réseau), mais le sonoff est trop gros à mon gout avec aqara seul à ce niveau de prix et ce niveau de rapport qualité prix (exit Moes, Nous et co qui fonctionnent quand ça veut). Sans surprise c'est parfait, réactivité instantanée à l'ouverture, mois d'1 seconde à la fermeture. -Ajouté à home assistant via zha en 1 clic avec le niveau de batterie et les variables de qualité réseau/connectivité zigbee remontées. C'est mis à la va-vite vite sur la porte pour le test, je pense qu'il y a moyen de cacher le capteur sous la porte avec la partie fixe montée perpendiculairement. On est pas dans le gadget me concernant car il m'arrive "régulièrement" de mal fermer ma porte de congélateur (j'ai une alerte home assistant à 2 min d'ouverture de porte) ... -Aussi, je confirme que la partie mobile du capteur est aimantée (et scotch double face fourni malgré tout pour cette partie). edit : si vous avez l'impression que le capteur se met en position "ouvert" avant l'ouverture physique de la porte, c'est parce-que c'est le cas (les 2 clips sont biens synchronisés). Là ou j'ai placé l'aimant, les 2 ou 3mm ou je tire sur la porte (avec l'accordéon de la porte du congélateur qui compense physiquement la déformation) suffisent à activer le capteur.
