In the smart home system, the WiFi smart valve is not only an “intelligent upgrade” of the traditional valve, but also a core control node for water safety and efficiency. Its flexible control methods, diverse functional advantages, combined with the linkage of water splash sensors to realize water leakage detection and automatic valve closing, can bring qualitative improvement to household water management.
The control logic of WiFi smart valves is designed around “convenience” and “flexibility”, supporting both immediate operation and automatic management, specifically including three dimensions:
- Remote Control: All-time Management on the APP End
With the supporting mobile APP (tuya app), users can achieve cross-space control:
◦ Immediate operation: Whether at home or out, users can remotely control the valve actions by clicking the “On/Off” button on the APP (such as closing the home main water valve when on a business trip to avoid water leakage when no one is on duty).
◦ Timed tasks: For regular water usage scenarios (such as balcony green plant irrigation, humidifier water replenishment), timed on/off can be set (such as “open the valve at 7 am every day for 30 minutes”) without manual intervention.
◦ Status monitoring: The APP displays the current status of the valve (on/off), operation records (such as the last valve closing time) and abnormal alarms (such as low battery, valve closing failure) in real time, allowing users to keep track of water usage dynamics at any time.
- Local Control: Double Guarantee for Emergency and Habit
To cope with network interruptions or the operating habits of the elderly and children, the WiFi smart valve retains local control capabilities:
◦ Physical button: The valve body is usually equipped with a manual switch button, and long pressing for 3 seconds can force the valve to open/close without relying on the network.
- Linkage Control: Scene-based Response Integrating into Smart Homes
As an “execution terminal” of smart homes, the WiFi smart valve can be linked with other devices to realize automatic logic:
◦ Linkage with humidity sensors: For example, when the bathroom humidity is higher than 90% (after bathing), the hot water valve is automatically closed to avoid hot water waste caused by forgetting to close the valve.
◦ Linkage with water splash sensors (core scenario): When the sensor detects water leakage, it immediately triggers the smart valve to automatically close, which is also a key design to ensure household water safety (detailed later).
Compared with traditional manual valves or non-networked smart valves, the advantages of WiFi smart valves are reflected in the following four aspects:
- Operational Convenience: Breaking Time and Space Constraints
It solves the pain point of “forgetting to close the valve” — for example, if you remember that the balcony faucet is not closed after going out, you can close the valve remotely through the APP to avoid water accumulation; when the elderly are alone at home, their children can assist in the operation remotely without worrying about complicated operations.
- Water-saving Performance: Precise Control to Reduce Waste
Traditional valves control the on-off time based on experience (for example, water may overflow due to forgetting to close during irrigation), while WiFi smart valves can reduce ineffective water use by more than 30% through timing and quantitative control (such as automatically closing the valve after replenishing 5L of water each time), which is especially suitable for families in water-scarce areas or those who pay attention to energy conservation.
- Safety Guarantee: Early Warning and Rapid Response
In view of the risks such as water leakage and pipe burst, the WiFi smart valve reduces losses through “active monitoring + remote intervention”: even without matching sensors, users can find abnormalities through the APP (such as the valve being continuously open for more than 24 hours) and close the valve remotely; if matched with sensors, the response speed can be increased to the second level.
- Compatibility and Expandability: Adapting to Multiple Scenarios
It supports 2.4GHz WiFi network (with wide coverage, suitable for large apartments) and can be linked with devices of different brands; at the same time, the valve body materials (copper, SS301) and interface specifications (1″-2″) are suitable for most household water scenarios (tap water, hot water, irrigation water).
The water splash sensor (also known as the water leakage sensor) is a device specially designed to detect liquid leakage. When combined with the WiFi smart valve, it can build a closed-loop safety system of “detection – response – alarm”, becoming the core line of defense for household waterproofing.
• Detection layer: Water splash sensors usually adopt electrode or infrared detection principles and are placed in areas prone to water leakage (such as under the washing machine, beside the bathroom floor drain, and at the water heater interface). When the sensor comes into contact with water (or detects a water splash signal), it immediately sends a “water leakage alarm” to the gateway via WiFi/Bluetooth.
• Decision-making layer: After receiving the signal, the gateway triggers the preset logic — sends an “immediate valve closing” command to the WiFi smart valve, and at the same time pushes an alarm through the APP (“Water leakage near the washing machine, the valve has been automatically closed”).
• Execution layer: After receiving the command, the WiFi smart valve completes the valve closing action within 3-5 seconds (the DC motor drives the valve core to close), cuts off the water source, and prevents the leakage from expanding.
• Timely stop loss: Traditional water leakage needs to be found manually (such as seeing water accumulation after returning home), which may have caused damage to the floor and damp furniture (resulting in property losses); while the linkage system only takes 3-5 seconds from detection to valve closing, which can control the water leakage range within 1 square meter and basically avoid major losses.
• Unattended guarantee: When traveling or on a business trip, the risk of household water leakage is the highest. The linkage between the sensor and the smart valve can realize “unattended automatic protection”, so that users do not have to worry about “their home being flooded thousands of miles away”.
• Graded response: Some high-end systems support “graded valve closing” — slight water splashes (such as water splashing when washing hands) only alarm without closing the valve, and continuous water leakage (such as pipe rupture) will automatically close the valve to avoid false triggering (requires the sensor to support sensitivity adjustment).
• Kitchen scenario: Install a water splash sensor under the dishwasher and water purifier. If the interface is loose and leaks, the smart valve immediately closes the kitchen main water valve to prevent sewage from seeping into the cabinet and corroding the boards.
• Bathroom scenario: Attach the sensor to the edge of the bathtub. If water overflows during bathing (or the faucet is not closed), the smart valve closes the hot water valve, and at the same time, the APP pushes an alarm to remind the user to handle it.
• Balcony scenario: Install a sensor next to the washing machine drain pipe. If the drainage is not smooth and causes water accumulation, the smart valve closes the balcony water valve to prevent water accumulation from seeping downstairs and causing neighborhood disputes.
The WiFi smart valve solves the problems of cumbersome operation, serious waste and safety hazards of traditional valves through “remote + local + linkage” multiple control methods; and the cooperation with the water splash sensor upgrades it from an “intelligent control tool” to a “water safety guard”. For modern families, this combination not only improves the convenience of life, but also builds an invisible “waterproof line of defense” through technical means, enabling smart homes to truly realize the core value of “worry-free, energy-saving and safe”.
