4. Setup and Installation
4.1 Installation Position and Direction
Important Considerations:
- Do not reverse the inlet/drain ports of the water valve.
- The position of the water outlet should be higher than the position of the water inlet.
- When the water temperature falls below 0°C and freezes, the water valve may not be able to open and close. The sensor in the water valve can detect a minimum water temperature of -10°C.
- When installing the water valve, be sure to wrap the waterproof tape to prevent water leakage.
Suggested Installation Location: Indoor main water inlet.

4.2 Water Pipe Installation
Tools Needed: Adjustable spanner, Allen wrench.
Installation Steps:
- Turn off the main water valve.
- Wrap waterproof tape around the adapter threads.
- Align the adapter with the municipal water main and tighten using an Allen wrench.
- Wrap waterproof tape around the copper pipe of the water valve and insert the waterproof silicone gasket into the adapter.
- Tighten the adapter nuts with the wrench.
- Install the other side of the water valve using the same method.

4.3 Power Installation
Ensure correct alignment of the power concave-convex groove during connection.
- Check the power supply interface slot.
- Align at the interface and press firmly.
- Turn the nut clockwise to secure.
- Turn on the power supply. Installation is finished.

5. Operating Instructions
5.1 App Download and Registration
- Download the "Smart Life" app from your mobile's APP Store or Google Play.
- Run the "Smart Life" application from your smartphone.
- Register for a new account or log in if you already have one.
5.2 Smart Wi-Fi Pairing
The device is in pairing mode (blue light) by default. If the standby light is not on or is on for a long time, long press the reset button (Access Key) for 6 seconds to enter standby mode, then proceed to add the device.
Method 1: Bluetooth Pairing (Suggested)
- Activate Bluetooth on your mobile phone.
- Open the "Smart Life" app. The device should be automatically searched by Bluetooth.
- Click "Add" when prompted.
Method 2: AP Compatible Mode Pairing
- Press the reset button (Access Key) until the device flashes slowly (pairing mode).
- Follow the APP tips to add the device.

5.3 Main Functions and Settings (App Interface)
The app provides comprehensive control and monitoring features:
5.3.1 Valve Control
The main app interface allows you to remotely open or close the water valve with a tap. The current valve status (open/closed) is clearly displayed.
5.3.2 View History
You can view detailed water consumption records by day, month, and year within the app, helping you track and manage water usage.
5.3.3 High and Low Flow Rate Alarm Settings
Alarms for high and low flow rates can be turned on or off (default is "on"). You can set the status of the valve after a flow alarm, choosing between no state change or automatic closure.
5.3.4 Water Consumption Zero Setting
This function allows for the removal or resetting of total water consumption data.
5.3.5 Flow Rate Unit Setting
The app allows you to switch between different flow rate units: gal/h, m³/h, and L/h.
5.3.6 Other Functions
- Push Notification Management: View individual device push messages or turn off all app pushes.
- Product Linkage: Set up automation scenes, for example, linking with a Tuya WiFi Water Leak Detector (sold separately) to automatically shut off the valve when a leak is detected.
- Unlinking Devices: Remove the device from your app.
- Sharing Device: Share control of the device with other users.
- Clear Record: Deleting and re-adding the device through the app will clear its records and restore default settings.

6. Maintenance
To ensure optimal performance and longevity of your Haozee Smart WiFi Water Valve, follow these maintenance guidelines:
- Regular Cleaning: Periodically inspect the valve and connections for any debris or buildup. Clean gently with a soft cloth.
- Battery Check: The built-in Ni-MH rechargeable battery provides backup power. Ensure the device is regularly connected to external power to keep the battery charged.
- Connection Integrity: Periodically check all pipe and power connections to ensure they are secure and free from leaks. Re-apply waterproof tape if necessary.
- Temperature Monitoring: Avoid exposing the valve to temperatures below 0°C (32°F) to prevent freezing, which can impair valve operation.
7. Troubleshooting
- Device Not Pairing: If the blue pairing indicator light is not flashing, long press the Access Key for 6 seconds to enter pairing mode. Ensure your phone's Bluetooth is active for easier pairing.
- No Remote Control via App in Battery Mode: This is normal behavior. In battery backup mode, WiFi automatically turns off, and remote app control is disabled. You can still control the valve locally using the physical buttons.
- Valve Not Operating (Battery Mode): If the battery voltage falls below 3.8V, local control may be unavailable. If it drops below 3.5V, the valve will automatically close and shut down. Ensure the device is connected to external power to charge the battery.
- Water Leakage: Check all pipe connections and ensure waterproof tape was applied correctly during installation. Tighten connections if loose.
- Valve Not Opening/Closing in Cold Weather: The valve may not operate if water temperature falls below 0°C due to freezing. Ensure the device is installed in an environment within its specified working temperature range (1-60°C).
7.1 User Tips
- Changing Flow Units: You can change the flow unit (e.g., from gallons to liters) by pressing and holding the On/Off switch for 6 seconds until the flow unit flashes, then use the Access Key to cycle through units and press On/Off once to confirm. Alternatively, this setting can be adjusted within the Smart Life app.
