Flood Leakage Detector | Linkage Alarm Sensor for Kitchen & Bathroom | Supports Tuya Smart Life & Zigbee2MQTT
A Tiny Sensor. A Massive Peace of Mind.
You’re at work. You’re on vacation. You’re sleeping.
A pipe bursts under your kitchen sink. Water spills onto the floor. Seeps into the cabinets. Soaks into the subfloor. Creeps toward the living room.
By the time you notice? Thousands in damage. Weeks of repairs. Insurance claim headaches.
Most of the time, you don’t know there’s a leak until it’s too late.
Unless you have a smart water leak sensor.
Meet the Zigbee Water Leak Sensor from ChetaXpress. It sits quietly under your sink, behind your toilet, next to your water heater. The moment it detects moisture — even a few drops — it sends an instant alert to your phone. It can trigger a siren. It can shut off your water valve. It can save your home.
And it works with Tuya Smart Life OR Zigbee2MQTT (Home Assistant). Choose your platform.

Why You Should Get This Water Leak Sensor — Right Now
Reason 1: Floods Are More Common Than You Think
Water damage is the most frequent home insurance claim — more common than fire or theft. A slow leak under a sink can rot cabinets for months. A burst supply line can release 5-10 gallons per minute. This sensor catches it early.
Reason 2: Know Immediately — Not Hours Later
Without a sensor, you might not notice a leak until water stains appear on the ceiling below or you step in a puddle. With this sensor, your phone alerts you instantly. You can act before damage spreads.
Reason 3: Automate Your Response (Linkage Alarm)
Connect this sensor to your smart home system. When water is detected:
-
Send a critical alert to your phone
-
Sound a siren
-
Turn on a camera to see the damage
-
Shut off your main water valve (with compatible smart valve)
-
Turn on lights in the affected area
Reason 4: Works with Your Existing System
Choose the version that matches your setup. Already have Tuya Smart Life? Get the Tuya version. Running Home Assistant with Zigbee2MQTT? Get the Z2M version. No need to change ecosystems.
Reason 5: Battery Powered — Place Anywhere
No wires. No outlets needed. Place it under any sink, behind any toilet, next to your water heater, beside your washing machine. Anywhere water might leak.
Reason 6: Tiny Size, Big Protection
The sensor is small and discreet. Sits flat on the floor. You’ll forget it’s there — until you need it.
Reason 7: ChetaXpress Approved
| Standard | How This Product Delivers |
|---|---|
| Impactful | Prevents thousands in water damage |
| Seamless | Place on floor. Pair to hub. Done. |
| Compatible | Choose Tuya or Z2M version. Works with your system. |

Real Customer Story (Early Review)
“I bought the Tuya version of this sensor for under my kitchen sink. Three weeks later, I got an alert at 2 PM — ‘Water detected.’ I rushed home. The supply line to my faucet had a pinhole leak. Water was dripping into the cabinet. Not a flood yet — but it would have been by morning. The sensor saved my cabinets, my floor, and probably a $5,000 insurance claim. Best $20 I’ve ever spent.”
— Mark T.
