WiFi Door and Window Contact Sensor
Check a door or window's contact state through Tuya Smart or Smart Life with a compact Wi-Fi sensor.
✅ See the reported open or closed state - The app receives supported contact events from the connected sensor.
✅ Review earlier openings - Event records provide a useful history of contact changes.
✅ Use opening in a smart routine - Compatible Tuya devices can respond to configured sensor events.
✅ Plan the next battery change - A low-battery reminder draws attention to the power condition.
A small contact with a useful status view
Fit the sensor and magnet in alignment when the door is closed, then connect the device to a 2.4 GHz network. Test both states and the intended phone notifications at the final mounting point.
This Wi-Fi version does not require a separate Zigbee gateway. Its notifications depend on the network and phone settings, and any linked lamp or camera is a separate compatible device.
