Shelly Flood Gen4 Smart Flood Sensor with Leak Cable – WiFi, Zigbee, Matter, Alexa, HomeKit

Protect what matters with Shelly Flood Gen4

Meet Shelly Flood Gen4, a smart flood sensor designed to detect water leaks early and help you prevent damage. It combines a precision leak sensor cable with fast alerts that arrive on your phone and compatible smart home hubs, so you can respond quickly, wherever you are.

Two standout features deliver broad value: extendable coverage and seamless compatibility. The extendable leak sensor cable lets you monitor a wider area beneath appliances like dishwashers, washing machines, and sinks. When moisture is detected, real-time notifications arrive on your phone and you can trigger a local alarm to deter further leaks.

Placement matters for protection. Basements and garages are common trouble spots—place Shelly Flood Gen4 in corners, near drains, or along pipes to catch issues early. Customizable alert modes and extended coverage keep you informed even when you’re away from home, so you can act quickly.

For vacation properties, battery-powered operation provides continuous monitoring without constant power needs. Use the Economic Alarm Mode to conserve energy while maintaining protection during extended absences.

Smart home integration is straightforward. The Gen4 works with the Shelly Smart Control App and supports major ecosystems including Alexa, Google Home, SmartThings, Apple HomeKit, and Matter. Create scenes that trigger other devices when a leak is detected, adding convenience to protection.

Reliability and support are part of the package: an IP44 rating suits damp spaces, and Shelly offers a solid warranty plus professional assistance to help you configure and manage devices remotely and safely.

What you get — a capable, versatile flood sensor that adapts to your space and habits, helping you monitor risk, receive timely alerts, and automate responses across your smart home.
