4. Setup
4.1 Battery Installation
The XIAOMI Night Light 3 requires 2 Lithium Ion batteries, which are included with the product.
- Gently twist or slide open the battery compartment cover, typically located on the back or side of the light unit.
- Insert the 2 Lithium Ion batteries, ensuring correct polarity (+ and -) as indicated inside the compartment.
- Close the battery compartment cover securely.
4.2 Mounting the Night Light
The night light offers versatile mounting options using its built-in magnet or the included 3M adhesive base.
Magnetic Attachment:
The night light can effortlessly adhere to magnetic surfaces such as refrigerators or other metallic furniture without the need for the adhesive base.
Using the 3M Adhesive Base:
For non-magnetic surfaces, use the provided 3M adhesive base. Please note that the adhesive is designed for one-time use only. Choose your location carefully before affixing.
- Select Location: Identify a suitable, smooth, clean, and dry surface. Recommended surfaces include wood, coated metal, or tiles. Avoid painted walls as the adhesive may damage the paint upon removal.
- Prepare Surface: Clean the chosen surface thoroughly to remove any dust, grease, or moisture.
- Apply Adhesive: Peel the protective backing from the 3M adhesive on the base.
- Affix Base: Press the base firmly onto the prepared surface. Apply consistent pressure for several seconds.
- Curing Time: Allow the adhesive to cure for 24 hours before attaching the magnetic light unit to the base. Pressing firmly during application can shorten the wait time.
- Temperature Consideration: For optimal adhesion, apply the adhesive within a temperature range of 21°C to 38°C (70°F to 100°F). If the temperature is below 10°C (50°F), gently warm the adhesive before use.
5. Operating Instructions
The XIAOMI Night Light 3 features a switch to select between different operating modes: OFF, ON (constant light), and AUTO (sensor mode).

Figure 4: The physical switch for selecting operating modes.
5.1 Mode Selection
- OFF: The light is completely off and will not activate.
- ON: The light remains constantly on, providing continuous illumination.
- AUTO (Sensor Mode): The night light automatically switches on when it detects human movement in a dark environment.
5.2 Sensor Mode Operation (AUTO)
In AUTO mode, the night light utilizes both a motion sensor and a light sensor for intelligent activation:
- Activation Conditions: The light activates only when it detects human movement AND the ambient brightness level is below 10 lux (i.e., in a dark environment).
- Auto-Off: If no human activity is detected for 15 seconds, the light will automatically switch off to conserve battery power.
- Sensor Range: The human body can be detected within a 120° angle centered around the XIAOMI logo. The detection range is approximately 5 meters (16.4 feet) in front and 3 meters (9.8 feet) to the side of the product.
- Factors Affecting Sensor: The effectiveness of the sensor is dependent on ambient temperature, brightness, human body size, and movement speed.
- Mounting Height: The sensor range provided is based on testing with the night light mounted at a height of 1.2 meters (3.9 feet), with the XIAOMI logo positioned as shown in Figure 1. The sensor range may vary with different mounting heights.
6. Maintenance
- Cleaning: Wipe the surface of the night light with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Battery Replacement: When the light dims or stops functioning, replace the batteries with new Lithium Ion batteries. Ensure correct polarity.
- Sensor Area: Keep the sensor area clear of obstructions to ensure optimal performance of the motion and light sensors.
