Multiprotocol leak sensor with an extendable cable for continuous coverage.

## Detect leaks along a cable, not only at one point

Shelly Flood Gen4 uses a flexible sensing cable that can follow pipes, appliances or cabinet edges. Compatible extension cables allow broader coverage while the built-in buzzer provides a local warning.

### Key specifications

- Wi-Fi, Zigbee, Bluetooth and Matter
- Flexible leak-sensing cable
- Three sensitivity profiles
- Four AA batteries
- IPX4 housing

**Use:** Position the cable where leaking water will reach it before damaging vulnerable materials.
