The Fibaro flood sensor offers a perfect mix of features, design and price, making it our HomeKit water leak detector. This fully wireless sensor runs on a single CR123A battery, which lasts up to two years, and connects directly to the HomeKit via Bluetooth. Although limited in range, Bluetooth makes pairing with your home app quick without having to download another app or creating an account.

Because Fibaro Flood is wireless, all you need after pairing is to place it next to one of the potential hot spots in the house, like under a sink. The Fibaro flood sensor takes it from there, monitoring the surface on which it leans for leaks with a set of tiny probes underneath. If water is detected, it can trigger an audible alarm and send an instant notification. The best part about the Fibaro flood is that it includes temperature detection, which puts the measurements right in the Home app, plus it also has tamper detection that can warn you if it's been moved out of position.


  • Completely wireless
  • Directly to the HomeKit connection
  • It also acts as a temperature sensor
  • Visual and audio alarms


  • Limited Bluetooth range
  • Works only with HomeKit
