A slow leak behind the washing machine does not announce itself. It soaks the subfloor for days, and you find out when the room starts to smell or the floor starts to lift. This sensor tells you the moment water touches it — wherever you are.
No hub. No gateway. No extra box to buy.
Most leak sensors at this price need a separate hub or base station before they will talk to your phone. This one connects straight to your home Wi-Fi. Unbox it, open the app, and it is running in about two minutes.
Please check before you order: this sensor connects to 2.4GHz Wi-Fi only. It will not connect to a 5GHz network. Most routers broadcast both, but some mesh systems combine them into one name — if yours does, you may need to split the bands or use a guest 2.4GHz network during setup.
Where people put them
Leaks start in predictable places, which is why most homes need more than one sensor:
- Under the kitchen sink
- Behind or beneath the washing machine
- At the base of the water heater
- Under bathroom vanities
- Beside the dishwasher
- Basement floor, sump pump area, or near the furnace
Four sensors cover a typical home. Each one is named separately in the app, so an alert tells you exactly which room to walk into.
How it works
- Water bridges the probes and the sensor triggers immediately
- Push notification goes to your phone through the Smart Life / Tuya Smart app
- Built-in audible alarm sounds at the sensor itself
- Works with Amazon Alexa and Google Assistant
- Add as many sensors as you like to one app account

Good to know
-
It alerts, it does not shut off water. This sensor tells you there is water. Stopping it is still a job for you or a plumber.
-
It needs Wi-Fi to notify you. If your internet is down, the local alarm still sounds, but no push notification will reach your phone.
