Product details

The Shelly Flood S Gen4 is an intelligent water detector that detects even the smallest water leaks before they lead to costly damage. Instead of a sensor cable, it uses three large stainless steel pads integrated into the base, which detect even clean, low-conductivity water such as condensate from air conditioners or distilled water. Its ultra-slim design allows it to be effortlessly placed under appliances or in tight spaces. The sensor supports two modes – flood detection and rain monitoring – as well as three alarm profiles: intensive, normal, and economic. With an IP67 rating and an integrated buzzer, it offers both instant smartphone notifications and local alarm messages. Setup and control are easy via the Shelly Smart Control App or your preferred smart home system. The Shelly Flood S Gen4 is ideal for use under appliances, at faucets, or in drip trays and can be paired with a smart faucet to automatically shut off the water in case of a leak.
