Maintenance
1. Battery Replacement
The sensor requires 2 AAA batteries. When the battery level is low, the app will send a low battery warning notification. Replace batteries promptly to ensure continuous operation.
To replace batteries, gently slide open the main sensor unit's cover, remove the old batteries, and insert new ones, observing correct polarity. Close the cover securely.
2. Cleaning
Wipe the sensor units with a soft, dry cloth as needed to remove dust or debris. Avoid using harsh chemicals or abrasive cleaners.
Troubleshooting
- Sensor not connecting to Wi-Fi: Ensure your Wi-Fi network is 2.4GHz. Check Wi-Fi signal strength at the sensor's location. Re-enter pairing mode and try connecting again.
- No notifications received: Verify that app notifications are enabled for the Tuya Smart Life app on your smartphone. Check the sensor's battery level. Ensure the sensor and magnetic strip are correctly aligned and within range.
- Delayed notifications: This can sometimes be due to network congestion or server response times. Ensure your Wi-Fi connection is stable.
- Sensor status incorrect: Check the physical alignment of the main unit and magnetic strip. They should be close together when the door/window is closed.
