The Aqara Door & Window Sensor T1 is a sleek, stick-on sensor that instantly detects when doors, windows—or even drawers and letterboxes—open or close, using a precise magnetic distance sensor. Forget tools: simply peel and stick it in place, and you’re ready to go.

Despite its small footprint, this little gem delivers over two years of battery life on a single CR1632 cell—thanks to its energy-efficient design. It also supports OTA updates, keeping its performance smooth and future-proof.
