## Description

Shelly's Flood S Gen4 is a smart sensor engineered with a unique large-surface triple-pad stainless-steel design for high sensitivity water detection. Featuring flexible connectivity, this device can be adopted into any WiFi, Zigbee or Matter ecosystem. This device features an ultra-compact design, meaning it can be installed under appliances, in tight spaces or under furniture. Ideal for non-invasive deployments, the Flood S Gen4 is battery-powered, enabling uninterrupted operation for up to 2 years.

The Shelly Flood S Gen4 features three built-in alarm styles: Intense, Normal and Economic, meaning you can customise this device to best suit your installation needs. Additionally, with multi-protocol connectivity, you can integrate this sensor into different ecosystems dependent on your pre-existing network - this device can be remotely controlled via the free Shelly app and enable instant alerts so you can act quickly even when you're not home.

Equipped with an integrated buzzer for local alerts, users can get an immediate audible warning when nearby, as well as triggering scenes in the Shelly app such as turning off appliances close to the sensor if water is detected. With an IP67 rated exterior, this sensor ensures continuous performance no matter the conditions.
