Tuya Wi-Fi Door & Window Sensors – 1, 2, 4 or 8 Sets
Check several doors or windows through the same smart-home app. These Wi-Fi contact sensors work with Tuya and Smart Life to report open or closed states. They are for households that want contact monitoring at one opening or across several rooms.
- ✅ Choose how many openings to monitor — Select one, two, four or eight sensor sets for your layout.
- ✅ Check status without visiting each room — The app brings reported contact states to your phone.
- ✅ Make lighting respond to an opening — Create a scene with a compatible smart light for the room you enter.
- ✅ Share routine checks with your household — Use the app's device-sharing function for other authorised users.
- ✅ Mount without running signal cables — The sensor and magnet attach to the opening and its frame.
Build contact monitoring around your rooms
Fit a sensor pair to each selected opening, with the main body and magnet aligned when closed. The mounting instructions specify a gap below 10 mm, so check the frame arrangement before ordering.
After Wi-Fi pairing, use the app to view contact status and configure notifications or scenes. Compatible lights and other devices are purchased separately; the sensor is not a lock and does not provide a guarantee against entry.
Each set consists of a sensor body and magnet. Choose the pack quantity you need, and check the unit's battery requirements before setup; batteries are not confirmed as included.
