Shelly Flood S Gen4

Shelly Flood S Gen4 is a smart water and leak sensor that detects even the smallest traces of water before they turn into costly damage. Instead of a sensor cable, it uses three large-surface stainless steel pads integrated into the base, detecting even clean, low-conductivity water such as air-conditioning condensate or distilled water. Its ultra-slim, low-profile design slides effortlessly under appliances and into tight spaces. It supports two modes – Flood Detection and Rain Detection – and three alarm profiles: Intense, Normal and Economic. With IP67 protection and a built-in buzzer, it delivers both instant phone notifications and local on-site alerts. Easily set up and controlled through the Shelly Smart Control app or your preferred smart home system such as Home Assistant, Homey, SmartThings, Google Home, Amazon Alexa and Apple Home. Shelly devices work 100% locally and only need a local network to operate. Use cases: Under appliances: slide the sensor beneath a washer, dishwasher or refrigerator to catch leaks at the source. Under sinks and valves: place it flat beneath P-traps, shutoff valves or filters to catch slow drips early. At the toilet: detect leaks from supply lines, tanks or failing seals. In a drip pan under a water heater or boiler: get notified the moment the pan fills or overflows. Automatic water shutoff: pair with a smart water valve to cut the water automatically when a leak is detected. Outdoor rain automation: enable Rain Detection and trigger scenes – pause irrigation, deploy awnings or close skylights. Connectivity: Multiprotocol: works via Wi-Fi, Zigbee and Bluetooth, Matter-certified for easy, future-proof integration across brands, Battery-powered (1x CR123A included) with up to 2 years of battery life.
