3.3. Physical Installation

The sensor consists of two parts: the main sensor unit and a smaller magnetic contact. These two parts must be installed close to each other (within 10mm) on a door, window, or other movable object and its frame.

Choose a Location: Identify a suitable flat surface on your door/window and its frame where the two sensor parts can be aligned when the door/window is closed. Ensure the notch side of both parts faces each other.
Clean the Surface: Wipe the installation area clean and dry to ensure proper adhesion.
Apply Adhesive: Peel the protective paper from the back of the 3M adhesive pads and attach them to the back of both the main sensor unit and the magnetic contact.
Mount the Sensor:
- Attach the main sensor unit to the fixed frame of the door/window.
- Attach the magnetic contact to the movable part of the door/window, aligning it with the main sensor unit. Ensure the gap between the two parts is less than 10mm when the door/window is closed.
Optional Screw Mounting: For a more secure installation, you can use the provided screws instead of or in addition to the adhesive pads. Mark the screw holes, drill pilot holes if necessary, and secure the sensor parts.
Test Installation: Open and close the door/window to verify that the sensor registers the change in status in the app.

Remove the old AAA batteries.
Insert two new AAA batteries, ensuring correct polarity. It is recommended to use high-quality, fresh batteries for optimal performance and battery life.
Close the battery compartment securely.

Note: Some users have reported that the sensor can consume batteries relatively quickly. Regular monitoring of battery status in the app is advised.

5.2. Cleaning

To maintain optimal performance, occasionally wipe the sensor units with a soft, dry cloth. Avoid using abrasive cleaners or solvents, as these can damage the device.

6. Troubleshooting

Problem	Possible Cause	Solution
Sensor not connecting to WiFi.	Incorrect WiFi band (5G instead of 2.4G). Incorrect WiFi password. Sensor too far from router. Router firewall settings.	Ensure your phone and sensor are connected to a 2.4G WiFi network. Double-check the WiFi password. Move the sensor closer to the WiFi router or use a WiFi extender. Temporarily disable router firewall or adjust settings to allow new devices. Reset the sensor and try pairing again.
No app notifications when sensor is triggered.	App notification settings disabled. Sensor offline. Low battery. Incorrect installation (gap too wide).	Check your phone's notification settings for the Tuya Smart/Smart Life app. Verify the sensor's status in the app; ensure it's online. Replace batteries with fresh ones. Ensure the gap between the main unit and magnetic contact is less than 10mm when closed.
Sensor not registering activity.	Low battery. Misalignment of sensor parts. Sensor malfunction.	Replace batteries. Re-align the main unit and magnetic contact, ensuring they are close and the notch sides face each other. If issues persist after troubleshooting, contact customer support.
Short battery life.	Frequent triggering of the sensor. Poor quality batteries. Weak WiFi signal (sensor uses more power to maintain connection).	Use high-quality, reputable brand AAA batteries. Ensure the sensor is within good range of your WiFi router. Consider if the installation location experiences excessive open/close events.
