Water rarely announces itself. This small white sensor sits on the floor where leaks start, and it alerts you the moment water touches its base, so a drip under a sink or behind a washer gets caught while the floor is still dry. It is built for homeowners and renters who want leak protection without drilling or a full alarm system.
Early flood detection: instant alert when water touches the sensor
- undetected water leaks
- costly flood and water damage
- hidden leaks behind appliances or under sinks
Catch the leak before it reaches your floor
Hidden drips soak floors and cabinets for days before anyone sees them. This compact sensor alerts you the moment water touches it, so a small leak stays small.
Triggered by the first drop, not the flood
Triggered by the first drop
Water touching the immersion contacts on the base sets off the alert. A drip too small to see still reaches those contacts, so the signal starts before the floor is wet enough to notice.
Low profile, easy to hide
The round white dome sits flat, so it slides under a washer lip or behind a cabinet kick without catching on anything. It looks like a small household fixture, not a security device.
Reports to your Aqara or Mi Home hub
The sensor belongs to the Xiaomi and Aqara ecosystem and sends its alert through your existing hub. If you already run home security cameras, the leak alert sits alongside them in the same app.
Placed in minutes, watching immediately
- 1Pick the lowest point
Choose the floor spot where water would collect first, such as the area under a washer's inlet and drain connections or the back of the cabinet under the sink.
- 2Confirm the sensor is dry
Wipe the base and check that the immersion contacts are clear of dust or debris. Set the sensor flat on a level surface.
- 3Pair it to the app
Add the sensor in the Aqara or Mi Home app through your hub, then check that the status shows it is online before you walk away.
A slow drip runs for days before anyone sees it
The stain comes first
A washer hose or supply line weeps onto the floor behind an appliance. Nobody sees it because the water runs under the machine and into the grout. Days later the cabinet base is soft and the ceiling below shows a brown ring.
One sensor on the lowest point
Water always finds the lowest spot, so the sensor goes there, flat on the floor. Its immersion contacts on the base are what trigger the alert, so the first drop that reaches them is the first thing you hear about.
You stop checking under the sink
Once the sensor is paired with your Aqara or Mi Home hub, the weekly flashlight check under the sink is no longer needed. The floor is watched while you are at work, asleep, or away for a week.

Questions and answers
No. The alert is triggered when water touches the immersion contacts on the base. A thin film of water that reaches those contacts is enough, so the signal starts at the first drop, well before the floor is visibly wet.
On the floor at the lowest point where water would collect. Behind a washer, place it under the drain hose and inlet valves. Under a sink, slide it to the back of the cabinet near the supply lines. Near a water heater, put it on the floor beneath the tank.
Yes. The sensor is a small round dome that sits on the floor, so nothing needs to be drilled or wired. Take it with you when you move and set it up again in the new place.
The sensor reports through an Aqara or Mi Home hub, so plan on having one in the home. Pairing and status checks happen in the app once the hub is set up.
A single sensor costs far less than the repairs a slow leak causes. Warped cabinets, replaced subfloor, and dried ceiling stains add up quickly, and one early alert can stop that damage before it starts.
