Product Details
The Shelly Flood Gen4 watches for water where you do not want it, under a sink, behind a washing machine, near a water heater, and sounds a loud alarm while sending an alert to your phone the instant it detects a leak. Catching a leak early can save a floor, a ceiling or a whole room.
It supports Wi-Fi, Bluetooth, Zigbee and Matter, so it works on your Wi-Fi without a hub and pairs into Apple Home, Google Home and Amazon Alexa. A built-in temperature sensor adds freeze and heat warnings, and an optional leak-detection cable extends coverage along its whole length for larger areas.
Pair it with a Shelly water valve to shut off the supply automatically, or with Home Assistant for custom routines. It is simple protection that pays for itself the first time it catches a leak.
