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

Smart flood protection that adapts to your home

Meet Shelly Flood Gen4, a compact, battery-powered flood sensor built to catch moisture the moment it appears. Equipped with a precision leak sensor cable, it monitors broader areas and sends instant real-time alerts to your phone, helping you respond quickly before a minor leak becomes a bigger concern. Seamless integration across popular ecosystems—WiFi, Bluetooth, Zigbee, Matter—lets you control and automate from the Shelly Smart Control app or your preferred smart home hub.

Your setup can be as simple or as expansive as you need. The extendable leak sensor cable lengthens detection coverage, so you can place the device under appliances, along pipes, or near drains to capture leaks at their source. When moisture is detected, you can customize responses to trigger local alarms, push notifications, or automate scenes with other Shelly devices for coordinated protection.

Where to use and how it helps

Basements, kitchens, garages, laundry rooms, and holiday homes are common sites for leaks and dampness. Shelly Flood Gen4 is designed for these spots with an IP44 rating that withstands splashes and dust in challenging corners. Battery operation keeps protection active even during power outages or long absences, and the app makes it easy to monitor status, adjust alerts, and extend coverage over time.

• Real-time alerts keep you informed wherever you are, reducing the time to react.
• Extendable leak sensor cable broadens the detection area for early warnings.
• Local alarms plus mobile notifications provide flexible, multi-channel protection.
• Battery-powered design supports protection in remote or seasonal properties.
• Easy remote setup and management via the Shelly Smart Control app or compatible hubs.

Smart home compatibility and practical benefits

Designed for today’s connected homes, Shelly Flood Gen4 works across multiple ecosystems and control methods. It supports WiFi, Bluetooth, Zigbee, and Matter, and pairs with Alexa, Google Home, SmartThings, and Apple HomeKit. You can build practical automations that respond to leaks—like turning on a local siren, sending a notification to your phone, or powering off a water valve in compatible setups. For seasonal properties, you can enable energy-saving modes to extend battery life while keeping temperature and moisture under watch.

Think of Shelly Flood Gen4 as part of a broader protection strategy rather than a single solution. It offers early detection, remote visibility, and scalable integration that fit a range of homes and lifestyles. While outcomes depend on your specific layout and devices, many users find the setup provides meaningful peace of mind and a faster path to protecting valuables and living spaces.
