Shelly Flood S Gen4

Shelly Flood S Gen4 – Smart Water Leak Sensor with Matter, Wi-Fi & Zigbee Protect your home from leaks before they become costly water damage. Shelly Flood S Gen4 is a compact, battery-powered smart water leak sensor designed for reliable detection in kitchens, bathrooms, utility rooms and other leak-prone areas. Its large-surface triple-pad stainless-steel sensor can detect even clean or low-conductivity water, while Wi-Fi, Zigbee, Bluetooth and Matter support make it easy to integrate into modern smart home systems. Receive remote notifications, trigger automations and get an immediate local warning through the built-in buzzer. Smart Water Leak Detection for Your Home Water leaks can start in places that are difficult to see. The slim, low-profile design of Shelly Flood S Gen4 allows you to position the sensor underneath washing machines, dishwashers and refrigerators, below sinks, near toilets or beside plumbing installations. The large stainless-steel sensing surface provides fast and reliable detection, including for clean and low-conductivity water such as condensation, distilled water or desalinated water. Key Features of Shelly Flood S Gen4 Reliable leak detection: Large-surface stainless-steel sensor pads detect water quickly, including clean and low-conductivity water. Wi-Fi 6 & Zigbee 3.0: Choose the connectivity protocol that best fits your smart home. Matter certified: Easily integrate the sensor into compatible Matter smart home ecosystems. Bluetooth 5 LE: Supports convenient setup and connectivity. Built-in buzzer: Receive an audible warning directly where the leak is detected. Remote notifications: Get notified when water is detected, even when you are away from home. IP67 protection: Designed for use in areas where splashes, spills and moisture are common. Up to 2 years battery life: Battery-powered operation provides flexible placement without additional wiring. Flood & Rain modes: Configure the sensor according to the type of water detection you need. Local automations: Create responsive smart home actions without relying entirely on cloud connectivity. Wi-Fi, Zigbee and Matter Connectivity Shelly Flood S Gen4 offers flexible multi-protocol smart home connectivity with Wi-Fi 6, Zigbee 3.0 and Bluetooth 5 LE. Matter-over-Wi-Fi support also makes it suitable for increasingly interoperable Matter-based smart homes. The sensor can work with the Shelly Smart Control app, Shelly Cloud, Home Assistant and other compatible smart home platforms, giving you the flexibility to build water protection into your existing automation system. Instant Leak Alerts – At Home or Away When water is detected, Shelly Flood S Gen4 can provide both local audible alarms and remote smart notifications. This helps you react quickly whether you are in the next room, at work or away from the property. Choose between three configurable alarm profiles – Intense, Normal and Economic – to balance notification frequency and battery consumption according to your requirements. Automatic Water Leak Protection Shelly Flood S Gen4 can become part of a wider smart water protection system. Combine leak detection with compatible smart relays, valves or home automation equipment to trigger actions automatically when water is detected. For example, a smart home automation can be configured to shut off the water supply when a leak is detected, helping limit damage before you are able to intervene manually. Where Can You Use Shelly Flood S Gen4? Under Washing Machines & Dishwashers Slide the compact sensor underneath appliances to detect small leaks before water spreads across the floor. Under Sinks & Near Plumbing Place the sensor beneath pipe connections, filters, traps and shut-off valves to detect slow drips or unexpected leaks. Bathrooms & Toilets Monitor areas around toilets, basins and other plumbing fixtures where leaks may otherwise remain unnoticed. Water Heaters & Boilers Position the sensor near a water heater, boiler or inside a suitable drip pan to receive an early warning when water appears. Holiday Homes & Unattended Properties Remote notifications make Shelly Flood S Gen4 particularly useful for properties that remain unattended for extended periods. Flood Detection and Rain Detection Modes Shelly Flood S Gen4 supports two different operating modes. Flood Detection is designed for areas where the presence of water should trigger an alarm, while Rain Detection can report a water state change without activating the flood alarm. Rain Detection can also be incorporated into smart home automations. For example, detected rain could be used to pause irrigation, retract or control awnings, or trigger compatible window and skylight automations. Compact IP67 Design With its compact profile and IP67 protection rating, Shelly Flood S Gen4 is designed for placement close to the areas where leaks are most likely to occur. Its battery-powered design means no additional power wiring is required, making installation simple and flexible. Why Choose Shelly Flood S Gen4? Shelly Flood S Gen4 combines smart water leak detection, flexible connectivity and home automation in a compact sensor. With Wi-Fi, Zigbee, Bluetooth, Matter support, IP67 protection, local alarms and remote notifications, it provides a flexible way to add early leak detection to a connected home. Use it as a standalone smart leak detector or integrate it with your wider Shelly and smart home ecosystem to create automated protection against leaks, flooding and unwanted water.
