Stechro WiFi Smart Water Leak Detector with App Alerts, 4 Adjustable Sensors & Rechargeable Gateway for Home Basements, Kitchen, Laundry, and Sinks

Key Features and Setup Process

The Stechro WiFi Smart Water Leak Detector is designed to give you peace of mind by protecting your home from water damage. It comes with a smart 2.4GHz WiFi gateway and four adjustable water sensors, allowing you to monitor up to 24 sensors throughout your house. This means you can cover all the vulnerable spots where leaks might happen, like basements, kitchens, bathrooms, and laundry rooms.

Setting it up is straightforward. Just connect the gateway to your home WiFi and bind the sensors through the TUYA app on your phone. The app lets you name each sensor, so you instantly know where a leak is detected. Plus, it lets you adjust the alarm volume up to 120dB and choose from 32 different ringtones. This customization means the alerts won’t catch you off guard, and you can even share notifications with family members or friends, so more eyes are watching your home.

• Smart WiFi gateway connects up to 24 sensors for whole-home coverage
• Easy setup and app control via TUYA for real-time alerts
• Customizable sensor names and alarm sounds
• Multi-user sharing for extra peace of mind

How the Rechargeable Gateway Enhances Connectivity

One of the standout features of this system is its rechargeable gateway. Unlike other models that need to be plugged in constantly, Stechro’s gateway can be charged and used wirelessly for up to 10 hours. This is a huge benefit if you experience power outages or want to move it around your home easily. You won’t have to worry about losing connection when it matters most. The app also alerts you when the gateway’s battery drops below 20%, so you’ll never forget to charge it on time.

This rechargeable design makes the whole system much more reliable and convenient. You don’t have to fuss with power cords or lose monitoring just because the outlet is busy or the power is off. It’s a smart upgrade that fits perfectly with a busy modern lifestyle.

Ideal Uses: From Basements to Kitchens

The Stechro water leak detectors are designed to work everywhere water damage might strike. Each of the four sensors features four detection points on the bottom for sensing leaks quickly, plus a front probe for detecting drips. This means the sensors can pick up even small leaks before they turn into big problems. You can place them under sinks, near washing machines, in basements, or anywhere water might pool unexpectedly.

Thanks to its IP66 waterproof design, the sensors can handle humid environments without any issues. This makes them perfect for bathrooms or laundry rooms where moisture is common.

Combining Flood Detection with Smart Lighting

The Onforu 65W Smart LED Security Light is a smart solution for anyone wanting to boost outdoor safety without fuss. This light isn’t solar-powered; instead, it uses a 2.4GHz WiFi connection to link with the Onforu app, giving you total control right from your phone. This means you can adjust settings like the colour temperature, brightness, and even the motion sensor’s range and delay time—all with a few taps. No more climbing ladders to tweak your lights! Plus, the app keeps a record of every time the sensor activates, so you always know when movement was detected around your home.

• WiFi connection for easy remote control
• Customizable motion sensor distance and delay
• Memory function saves your preferred settings

Motion Sensor Benefits for Outdoor Security

Thanks to the upgraded PIR motion sensor, this Onforu light offers excellent detection with up to a 180° angle and a range of almost 73 feet. That’s a big coverage area for catching any unexpected visitors or wildlife near your property. You can set the delay off time anywhere from just 6 seconds to a full hour, which means the light stays on exactly as long as you need it. The app even lets you choose from three motion sensing distances and five brightness modes, so the light responds perfectly to your environment. This thoughtful design helps reduce false alarms and saves energy by lighting up only when it’s truly needed.

• Wide 180° detection angle
• Long detection distance of 72.7 feet
• Custom delay off time and sensitivity settings

Adjusting Brightness and Colours via the App

One of the coolest features is the stepless dimming system and adjustable colour temperature, which ranges from warm white (2500K) to cold white (6500K). You’re not limited to just a few preset modes; instead, you can fine-tune the brightness in five steps and pick any shade along the warm-to-cool spectrum. This makes the light perfect for any occasion—whether you want a soft glow for a quiet evening or bright daylight for security purposes. The memory function means your chosen settings stick, so you don’t have to keep adjusting them every time.

Each sensor can spot leaks early, whether it’s a slow drip under the sink or a sudden flood near your washing machine. With six sensors, you can keep watch in all the tricky spots like the basement, kitchen, bathroom, laundry room, and even near pipes or drains.

Plus, the gateway supports up to 24 sensors, so if you want to add more later, you can easily expand your system. The wide 328-foot range of the sensors means you don’t have to worry about signal loss even if the sensors are spread out over a large area.

The system works on 2.4GHz WiFi (not 5GHz), which is common in most homes, making setup straightforward. The app also lets you control the alarm volume and choose from 32 ringtones, so you can pick sounds that suit your home environment. Adjusting these settings remotely means you don’t have to rush back home to silence a false alarm or change tones.

It’s important to note that while app notifications are free, SMS and call alerts cost extra through a third-party service. But for most people, the app notifications alone offer all the smart alerts needed to stay safe.

• Instant leak alerts sent to your phone/tablet
• Works with TUYA Smart App on iOS and Android
• Customizable alarm volume and ringtone options
• Free push notifications keep you informed anywhere

Placement Tips for Maximum Flood Detection

To get the most from this water leak detector, placing the sensors in the right spots is key. Use the top drip sensor where small leaks might start, like under faucets or near pipes, and the four bottom flood probes where water might pool, such as on the floor by your washing machine or basement floor drains.

Think about areas prone to leaks like behind the toilet, under the kitchen sink, or near your bathtub. Setting the sensors here means you’ll catch leaks early before they cause bigger problems.

3-Pack WD71 Water Leak Detector with 120dB Alarm, WiFi Gateway Compatible (Gateway Not Included), Easy Installation for Home, Basement, Bathroom, Sink, and Laundry Flood Prevention

Standalone Use vs WiFi Gateway Integration

The 3 Pack WD71 water alarm detectors are smart and flexible. You can use each sensor on its own or connect them to the WiFi Water Leak Detectors W13 Hub for a smarter home setup. If you use it alone, the sensor sounds a loud 120dB alarm right away when it detects water. This is great if you’re nearby and want an instant warning.

But pairing these sensors with the W13 gateway unlocks even more benefits. The gateway connects to your home’s 2.4GHz WiFi and sends you instant alerts on your phone through the “Tuya Smart” app. That way, even if you’re at work or on vacation, you’ll know the moment a leak starts. You can also share access with family members so everyone stays in the loop. The hub supports up to 24 WD71 sensors, perfect for large houses or multiple high-risk areas.

Just remember, it only works on 2.4GHz WiFi networks, not 5GHz. This ensures stable connection and strong signals, especially indoors where walls can block signals. The range is pretty good too — up to 328 feet in open spaces and about 150 feet inside.

Installation Tips for Quick Setup

Setting up the WD71 detectors is a breeze. They come powered by AAA batteries, so no wiring is needed. Just place the sensor flat where you want protection, and it’s ready to go.

For those using the WiFi gateway, connect it to your home router and link it to the “Tuya Smart” app. The app guides you through adding each sensor quickly. The app also lets you schedule when the detectors are active. For example, you can turn off the alarm at night to avoid waking everyone or skip arming on rainy days when false alarms might pop up.

The dual-sensor design makes installation easier too. The top probes detect small drips, while the waterproof bottom probes sense pooling water. This means early leak detection without false alarms. Just make sure more than two bottom probes get wet before the alarm triggers. This feature helps avoid false alerts from humidity or small splashes.

Where to Place These Detectors in Your Home

These water leak detectors are perfect for high-risk spots in your home. Think about areas like the basement, bathroom, under sinks, laundry rooms, or near windows where water damage might happen.

The dual-probe design means they catch leaks in two ways: early drips on the top sensors and standing water on the bottom. So placing them right next to pipes, washing machines, or water heaters gives you the best protection.

Because the alarm is loud (up to 120dB), you’ll hear it before water causes serious damage.

5-Pack Water Leak Detectors with 100dB Alarm for Basement, Bathroom, Kitchen, and Laundry – Flood and Drip Sensor for Pipes, Drains, Sinks, and Faucets

Multiple Detectors for Wider Home Protection

This 5-pack of water leak detectors lets you cover more areas in your home where leaks can happen. Each detector has two water-sensitive probes in front to catch slow drips from pipes or drains, and four probes on the back to sense water on the floor. This double detection system works at the same time, so no matter where water shows up, you get an early warning. That’s especially helpful in spots like basements, kitchens, bathrooms, or laundry rooms where leaks often start unnoticed. With five units, you can place them strategically around your home for peace of mind that small leaks won’t turn into costly floods.

• Detects both drips and flooding at once
• Multiple units for full-home coverage
• Compact size fits tight spaces easily

Understanding the 100dB Alarm Strength

This water leak detector emits a loud 100-decibel alarm when it senses water. That’s about as loud as a lawn mower, so you’re sure to hear it even if the leak happens in a noisy basement or far from living spaces. Plus, the device has a mute button you can press once you reach the leak, so you’re not stuck with a blaring noise while you fix the problem. This loud and clear alert system means you don’t have to rely on visual checks alone. It actively protects your home by waking you up or grabbing your attention fast before water damage worsens.

• Very loud alarm for immediate notice
• Mute button for easy silencing
• Works well in noisy or distant areas

Detecting Different Types of Water Leaks

What makes these detectors stand out is their ability to spot both small drips and larger floods thanks to their smart probe setup. The front probes are perfect for catching drips from sinks, faucets, or leaking pipes, while the rear probes sense moisture on floors, which helps detect flooding early. This means whether you have a slow leak or a sudden burst, you’ll get an alert right away.
