Haozee WiFi Smart Water Valve and Automatic Shutoff,with Wi-Fi Water Leak Detector,Water Flow Meter,Built in Rechargable Battery,for DN20 3/4-Inch Diameter Pipe

Remote One-Tap Control: Open or close your main water valve from anywhere in the world using your smartphone.

Real-Time Usage Tracking: Monitor your live water flow and total consumption 24/7 to identify hidden leaks and save on utility bills.

Instant Mobile Alerts: Receive immediate push notifications for abnormal flow or potential leaks directly to your device.

Smart Home Integration: Fully compatible with the Tuya Smart ecosystem for seamless automation with other smart devices.

Elevate your home automation with our Gen 2 Ultrasonic Smart Valve. It doesn't just display data; it acts as an intelligent guardian for your plumbing system. By utilizing advanced flow algorithms and customizable scene linkage, you can prevent disasters before they happen.

• Pipe Burst Prevention (High Flow Alarm): Set a smart automation. If abnormal high water flow is detected (indicating a potentially catastrophic pipe burst), the valve automatically shuts off the main water supply instantly and sends an urgent alert to your phone.
• Frozen Pipe & Low-Pressure Alerts (Low Flow Monitoring): It also detects abnormally low flow rates. Set linkage to receive notifications when flow is too low during freezing weather (indicating potential pipe freezing) or when municipality water pressure is insufficient, allowing you to troubleshoot immediately.

Traditional mechanical water meters rely on moving parts that wear out, clog, or lose accuracy over time. Our valve utilizes W-Type Ultrasonic technology, which sends sound waves through the water flow to measure usage with medical-grade precision.

(Bullet Points)

• Non-Invasive Measurement: With zero moving parts inside the pipe, there is no mechanical wear and no risk of the sensor clogging over years of use.
• High-Sensitivity Leak Detection: Capable of detecting the smallest "pinhole" leaks that traditional meters often miss, saving you from hidden water damage.
• Unobstructed Flow: The smooth, full-bore internal design ensures that your home’s water pressure remains strong and unaffected.
• Long-Term Reliability: Since the technology doesn't rely on physical friction, the measurement remains as accurate in year 10 as it was on day 1.

Continuous Power via AC Adapter (5V/2A): Plug into any standard outlet for full-featured performance, including 24/7 WiFi connectivity, real-time data monitoring, and instant remote control via your smartphone.

Reliable Battery Backup (3x AA Ni-MH): Equipped with a user-replaceable, rechargeable Nickel-metal hydride battery system. Even during a total power outage, your home remains protected.

Autonomous Offline Security: In battery-only mode, the device intelligently disables WiFi to conserve energy but maintains its most critical function—the ability to shut off the valve locally via the physical buttons.

Fail-Safe Design: Whether the power is out or the internet is down, the integrated ball valve remains fully operational. You’ll never be locked out of your own water system.

"Total Home Protection Through Intelligent Automation"
Turn your smart water valve into a proactive defense system. By linking your valve with the Tuya Smart Water Leak Sensor, you can stop floods before they even start. Whether you are sleeping or away from home, your plumbing will now think for itself.

How It Works (IF/THEN Logic):

• IF Leak Detected: When a water sensor placed near your dishwasher, water heater, or washing machine detects moisture, it instantly sends a signal to the valve.
• THEN Auto Shut-Off: Within seconds, the smart valve automatically rotates to the SHUT position, cutting off the main water supply to prevent costly damage.
• Stay Informed: You will receive an immediate push notification on your smartphone via the Tuya Smart/Smart Life App, so you know exactly what is happening in real-time.

Designed to integrate seamlessly into your home’s main water line. The robust, vertical installation shown here demonstrates our valve's compatibility with standard copper piping. Featuring heavy-duty NPT brass fittings and a compact, splash-proof housing, it's built to withstand the humid environment of a typical American basement while providing 24/7 protection
