The 2 m linear cable included by default, extendable up to 150 m, reliably detects water leaks along its entire run—ideal along pipes, under appliances, and in large rooms.
Broad connectivity ensures easy integration with Apple HomeKit, Google Home, Home Assistant, and other platforms. Management is quick via the Shelly app and the built‑in web interface.
The built‑in buzzer signals flooding with a long tone and also reports a low battery with a short beep. Choose Intensive, Normal, or Eco modes based on the environment.
Shelly Flood Gen4 detects water the moment it appears—under a washing machine, dishwasher, boiler, or in a basement. The 2‑meter linear detection cable covers long sections and can be extended up to 150 m, making it easy to secure piping, utility rooms, and hard‑to‑reach corners. The integrated sound alarm and instant notifications help prevent costly damage.
With multiple protocols—Wi‑Fi, Bluetooth, Zigbee and compatibility with the Matter standard—the sensor connects seamlessly to ecosystems like Apple HomeKit, Google Home, Home Assistant, Amazon Alexa, or Samsung SmartThings. Battery operation (4× AA) and IP44 provide installation freedom indoors and in semi‑open spaces.
Select the mode for the location: Flood Detection for rapid alerts in critical zones, or Rain Detection for subtle monitoring of the first drops on terraces and under canopies. Three alarm levels (Intensive, Normal, Eco) tailor loudness and power consumption to the scenario.
