D02 Tuya Wi-Fi Door & Window Contact Sensor
Check a door or window's reported open or closed state from your phone. The D02 Wi-Fi contact sensor connects to Tuya Smart or Smart Life for status updates and compatible scenes. It is for households adding contact monitoring to a smart-home setup.
- ✅ Check an opening from your phone — View its reported state in the app when you want to check a door or window.
- ✅ Notice changes in your routine — Configure app notifications for opening and closing events.
- ✅ Link an opening to another action — Use compatible Tuya devices in scenes, such as switching a light when a door opens.
- ✅ Fit around an existing frame — Separate sensor and magnet pieces mount alongside one another without a cable between them.
Bring contact status into your smart-home routine
Mount the main sensor and magnet on the moving and fixed parts of a suitable door or window. Align the marks and keep the closed gap within the mounting guidance so the contact can report state changes.
Pair the selected Wi-Fi version with the app, then configure the notifications or scenes you want. Connected lights, sirens and other smart devices are separate products; they are not included with the sensor.
The compact pieces suit discreet placement beside an opening. Status reporting depends on installation, battery condition and connectivity; the sensor does not lock the door.
A compact main unit and magnet form the contact sensor.
Check reported contact status in the connected app.
Compatible smart lights can form part of a configured scene.
