Tuya Smart Life WiFi Water Leak Sensor – Know in seconds, before it’s too late
A dripping pipe in the middle of the night. A washing machine overflowing. A blocked sink while you’re out of the house. Water damage happens fast and costs a fortune to repair. The Tuya Smart Life WiFi Water Leak Sensor alerts you instantly—both via your phone and a local audible alarm—before the water reaches your flooring.
Note: This device requires a 2.4GHz Wi-Fi network to connect. It is not compatible with 5GHz networks.
Why choose this model? (Key benefits):
- Instant water detection — The metal contacts at the base detect leaks and trigger the alarm in under a second, day or night.
- No hub, no wires — Connects directly to your 2.4GHz Wi-Fi and works straight out of the box, powered by the included battery.
- Push notifications anywhere — Get alerts on your phone via the Tuya Smart or Smart Life app (Android and iOS), whether you’re at the office or on holiday.
- Long-lasting battery (~12 months) — Set it and forget it; it works in the background without needing constant recharging.
- Smart automations — When paired with a Tuya smart water valve, it can automatically shut off your water supply upon detecting a leak, with no human intervention required.
- Family sharing — Multiple users can receive alerts simultaneously through the same app without complicated configuration.
Details and Performance
At the base of the unit are two metal contacts that detect the presence of water the moment the liquid bridges them. The response is twofold: a local audible alarm for those nearby and a push notification on your phone for those further away. Communication is handled via 2.4GHz Wi-Fi (IEEE 802.11 b/g/n), the standard protocol for smart home devices—ensuring a stable, energy-efficient connection that preserves battery life.
Native integration into the Tuya Smart ecosystem turns this from a simple detector into an automation hub: it can trigger a dedicated siren, alert your family group, or initiate a shut-off sequence via a compatible Tuya smart water valve.
