3.2. Physical Installation

The sensor consists of two parts: a main unit and a magnetic strip. These two parts must be installed on a door/window and its frame, or two adjacent surfaces, with a maximum allowed gap of 0.86 inches (approximately 2.2 cm) when the door/window is closed.

Choose your preferred installation method:

• Adhesive Tape: Clean the surface where you intend to install the sensor. Peel off the protective backing from the double-sided adhesive tape and firmly press the main unit and magnetic strip onto the desired locations. Ensure the alignment marks on both parts face each other.
• Screws: For a more secure installation, use the provided screws and wall plugs. Mark the positions for the screw holes on the door/window and frame. Drill pilot holes if necessary, then attach the main unit and magnetic strip using the screws.

4. Operating Instructions

4.1. Basic Functionality

The sensor detects when a door or window is opened by sensing the separation of its two magnetic components. When separated, it triggers an alarm and sends notifications to your smartphone.

4.3. Voice Control

The sensor is compatible with Amazon Alexa and Google Home. Once integrated with your smart home system, you can use voice commands to check the status of your doors/windows or arm/disarm the sensor (depending on specific smart home routines you set up).

5. Maintenance

• Battery Replacement: When the app indicates a low battery level, replace both AAA batteries promptly to ensure continuous operation.
• Cleaning: Wipe the sensor with a dry, soft cloth. Do not use liquid cleaners or abrasive materials.
• Sensor Alignment: Periodically check that the main unit and magnetic strip remain properly aligned and the gap does not exceed 0.86 inches.

6. Troubleshooting

Q: The sensor is not connecting to the app.

A: Ensure your WiFi network is 2.4GHz, as the sensor does not support 5GHz. Check that your phone is connected to the same 2.4GHz network during pairing. Try restarting your router and the sensor, then attempt pairing again.

Q: The alarm is not sounding or I'm not receiving notifications.

A: Check the battery level in the app and replace batteries if low. Verify that the alarm sound and notifications are enabled in the Smart Life/Tuya app settings. Ensure the sensor is within range of your WiFi router.

Q: The sensor is not detecting door/window openings.

A: Check the physical alignment of the main unit and magnetic strip. Ensure the gap between them is no more than 0.86 inches when the door/window is closed. Re-position if necessary.

Q: The alarm is too quiet or too loud.

A: Adjust the alarm volume settings within the Smart Life/Tuya app.
