4. Setup
4.1 Battery Installation
- Gently slide open the back cover of the sensor.
- Insert two AAA batteries, ensuring correct polarity (+/-).
- Close the back cover securely.
4.2 Pairing with Apple HomeKit
To add the Onvis SMS2-K to your Apple HomeKit system:
- Ensure your iOS device is connected to a 2.4GHz Wi-Fi network.
- Open the Apple Home app on your iOS device.
- Tap the "+" icon in the top right corner and select "Add Accessory".
- Scan the HomeKit setup code located on the back of the sensor or on the included manual. If scanning fails, manually enter the 8-digit code.
- Follow the on-screen prompts to name your sensor and assign it to a room.
- For Thread functionality, ensure you have an Apple HomePod mini or a compatible Thread Border Router set up as a home hub.
4.3 Mounting the Sensor
The sensor can be wall-mounted or placed on a flat surface.
- Wall Mount: Use the provided adhesive pads to secure the sensor to a clean, dry, flat surface. Ensure the sensor is positioned to cover the desired detection area.
- Placement: For optimal motion detection, place the sensor where movement is expected, such as near doorways or in high-traffic areas. Avoid placing it directly facing heat sources or in direct sunlight, which can affect temperature readings and trigger false motion alerts.

5. Operating Instructions
5.1 Motion Detection
The PIR (Passive Infrared) sensor detects movement within its range (16-32 feet). When motion is detected, the sensor can trigger automations in Apple HomeKit, such as turning on lights or sending notifications.

5.2 Temperature and Humidity Monitoring
The sensor continuously monitors ambient temperature and humidity. These readings are updated automatically every 15 minutes and can be viewed in the Apple Home app or the Onvis Home app. You can also ask Siri for current room conditions.

5.4 Customizing Alerts and Schedules (Onvis Home App)
For advanced customization, download the Onvis Home app from the App Store. This app allows you to:
- Set specific time slots for motion detection to align with your daily routine.
- Adjust motion sensitivity to prevent unnecessary alerts.
- View historical data for motion, temperature, and humidity.

6. Maintenance
6.1 Battery Replacement
When the battery level is low, you will receive a notification in the Apple Home app. To replace the batteries:
- Slide open the back cover.
- Remove the old AAA batteries.
- Insert two new AAA batteries, observing correct polarity.
- Close the back cover.
6.2 Cleaning
Wipe the sensor with a soft, dry cloth. Do not use liquid cleaners or abrasive materials, as these can damage the device.
7. Troubleshooting
- Sensor not responding/offline:
- Check battery level and replace if necessary.
- Ensure the sensor is within range of your Apple HomeKit hub (e.g., HomePod mini, Apple TV, iPad).
- Verify your HomeKit hub is online and functioning correctly.
- Restart your HomeKit hub.
- Inaccurate temperature/humidity readings:
- Ensure the sensor is not placed near heat sources (e.g., direct sunlight, vents) or in areas with extreme humidity fluctuations.
- Allow some time for the sensor to stabilize after initial setup or relocation.
- False motion alerts or no detection:
- Adjust the sensor's sensitivity settings in the Onvis Home app.
- Ensure the sensor's field of view is clear of obstructions.
- Avoid placing the sensor where pets or moving objects might trigger it unintentionally.
- Check the mounting height and angle to optimize detection coverage.
- Cannot add to HomeKit:
- Ensure your iOS device is on a 2.4GHz Wi-Fi network during pairing.
- Verify the HomeKit setup code is entered correctly.
- Reset the sensor (refer to the Onvis Home app or product support for specific reset instructions if needed).
