1. Introduction
The PHOVOLT WiFi Motion Sensor is a smart device designed to enhance home security and automation. It provides real-time motion detection and integrates with smart home ecosystems to create automated routines and alerts. This manual provides detailed instructions for setting up, operating, and maintaining your motion sensor.
2. Product Overview
The PHOVOLT WiFi Motion Sensor is a compact and discreet device that uses passive infrared (PIR) technology to detect movement. It connects directly to your 2.4 GHz Wi-Fi network, eliminating the need for a separate gateway. Key features include:
- Direct Wi-Fi Connectivity: Connects to your 2.4 GHz Wi-Fi network without a hub.
- Smart Home Compatibility: Works with Alexa, Tuya Smart, and Smart Life APP for seamless integration. Note: Not compatible with Smartthings, IFTTT, Homekit, or Home Assistant.
- Custom Routines: Create personalized routines via the Alexa app for automated actions like turning lights on/off or sending messages.
- Real-time Alerts: Receive instant notifications on your mobile app when motion is detected.
- Wide Detection Range: Detects motion up to 8 meters away with a 128-degree detection angle.
- Battery Powered: Operates on 2 AAA batteries for flexible placement.

3. Safety Information
Please read and follow these safety guidelines to ensure safe operation and prevent damage to the device:
- Do not expose the device to extreme temperatures, direct sunlight, or moisture.
- Use only specified AAA alkaline batteries. Ensure correct polarity when inserting batteries.
- Keep the device out of reach of children and pets.
- Do not attempt to disassemble or repair the device yourself. Contact support if issues arise.
- Avoid placing the sensor near heat sources or in areas with strong air currents, as this may cause false detections.
4. Package Contents
Your PHOVOLT WiFi Motion Sensor package should contain the following items:
- 1 x PHOVOLT WiFi Motion Sensor (Model: PH-P01)
- 1 x User Manual
- 2 x AAA Alkaline Batteries (may be pre-installed or included separately)

5. Setup
5.1 Battery Installation
- Gently open the back cover of the motion sensor.
- Insert two AAA alkaline batteries, ensuring the correct positive (+) and negative (-) polarity.
- Close the back cover securely.
5.2 App Download and Account Creation
- Download the 'Tuya Smart' or 'Smart Life' app from your smartphone's app store (iOS or Android).
- Register for a new account or log in if you already have one.
5.3 Device Pairing
Ensure your smartphone is connected to a 2.4 GHz Wi-Fi network. The sensor does not support 5 GHz Wi-Fi.
- Open the Tuya Smart or Smart Life app.
- Tap the '+' icon in the top right corner to add a device.
- Select 'Security & Video Surveillance' > 'Motion Sensor (Wi-Fi)'.
- Follow the on-screen instructions to put the sensor into pairing mode (usually involves pressing and holding a button on the sensor until an indicator light flashes).
- Enter your 2.4 GHz Wi-Fi network password when prompted.
- Wait for the app to discover and connect to the device. Once connected, you can rename the sensor.
5.4 Placement and Mounting
The PHOVOLT WiFi Motion Sensor is designed for wall mounting. Consider the following for optimal performance:
- Place the sensor in an area where motion detection is desired, such as hallways, entryways, or rooms.
- Mount it at a height that allows for maximum coverage of the detection area (up to 8 meters, 128-degree angle).
- Avoid direct line of sight with windows or heat sources that could cause false triggers.
6. Operating Instructions
6.1 Motion Detection and Alerts
Once set up, the sensor will continuously monitor for motion within its detection range. When motion is detected:
- The sensor will send an immediate notification to your linked Tuya Smart or Smart Life app.
- You can view a history of detected movements within the app.
6.2 Smart Home Automation with Alexa
Integrate your PHOVOLT Motion Sensor with Amazon Alexa to create powerful automation routines:
- Ensure your Tuya Smart or Smart Life account is linked to your Alexa app.
- In the Alexa app, navigate to 'Routines'.
- Create a new routine and select 'When this happens' > 'Smart Home' > choose your PHOVOLT Motion Sensor.
- Select 'Motion Detected'.
- Under 'Add action', choose what you want Alexa to do (e.g., turn on smart lights, play a message, activate a smart plug).
6.3 Security Monitoring
The sensor can act as a first line of defense for your home security. When armed, any detected movement will trigger an alert, allowing you to monitor your property remotely.
7. Maintenance
7.1 Battery Replacement
When the battery level is low, the app will notify you. Replace the two AAA alkaline batteries as described in Section 5.1. Using fresh batteries ensures optimal performance and connectivity.
7.2 Cleaning
To maintain accurate detection, periodically clean the sensor lens with a soft, dry cloth. Do not use liquid cleaners or abrasive materials.
8. Troubleshooting
If you encounter issues with your PHOVOLT WiFi Motion Sensor, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Device fails to connect to Wi-Fi. | Incorrect Wi-Fi band (5 GHz), weak signal, incorrect password. | Ensure your router is broadcasting a 2.4 GHz network. Move the sensor closer to the router. Double-check your Wi-Fi password. Try re-pairing the device. |
| Delayed alerts or automation. | Network latency, app settings, sensor placement. | Check your internet connection speed. Ensure the app has necessary permissions. Adjust sensor placement for optimal signal. Note that a slight delay (2-5 seconds) can be normal for cloud-based smart devices. |
| Frequent false alarms. | Heat sources, strong air currents, direct sunlight, pets. | Relocate the sensor away from windows, vents, heaters, or areas where pets frequently move. |
| Short battery life. | Frequent detections, low-quality batteries. | Ensure you are using high-quality alkaline AAA batteries. Reduce the frequency of detections if possible through app settings (if available). |
| Sensor not detecting motion. | Low battery, obstructed view, incorrect placement. | Replace batteries. Ensure the sensor's view is unobstructed. Adjust placement to cover the desired area. |
