Protect your home and property from costly water damage with the Shelly Flood S Gen4. Powered by next-generation Gen4 hardware architecture, this compact, battery-operated smart leak detector provides instant audio, visual, and wireless alerts the moment water bridges its detection contacts.
Equipped with dual Wi-Fi 6 and Bluetooth 5 LE connectivity, along with native Matter-over-Wi-Fi support, the device integrates seamlessly into Home Assistant, Shelly Smart Control, and major smart home platforms. Alongside flood monitoring, it features an integrated ambient temperature sensor to track room conditions and trigger automated anti-freeze heating routines before pipes freeze.
Key Features:
- Instant Water Leak Detection: Dual floor-level gold-plated contacts detect minor leaks or sudden standing water to trigger immediate local buzzers and remote notifications.
- Integrated Temperature Sensor: Continuously monitors ambient room temperature to alert you of sudden drops or freeze risks in vulnerable plumbing areas.
- Gen4 Multi-Protocol Connectivity: Features Wi-Fi 6 and Bluetooth 5 LE with Matter-over-Wi-Fi support for robust network stability and cross-platform flexibility.
- Built-In Acoustic Alarm & LED: Features an integrated buzzer and visual LED indicator for direct local warning even if offline.
