HomeKit: Close the water valve if leak detected

Description

Water leaks often happens in some hidden places due to the natural corrosion caused by flowing water. What is more, a stuffed sink can easily spring a leak as well. That is why, it is the FIBARO Flood Sensor placed under your kitchen sink will act immediately if there are any drips detected. You can set an automation which will cut off the water by turning off the solenoid valve. To be able to set this automation, you need to connect the FIBARO Single Switch to a solenoid valve (100-240V AC, 50/60 Hz). Only then you will be able to control it via HomeKit.

Please consider whether to use normally open or normally closed solenoid valve, as:

  • normally open valve, in case of a power failure, will stay open,
  • normally closed valve, in case of a power failure, will stay closed.

Requirements

  • iPhone or iPad,
  • Home hub (Apple TV, HomePod, or iPad),
  • FIBARO for HomeKit Devices app,
  • FIBARO Flood Sensor (FGBHFS-101),
  • FIBARO Single Switch (FGBHS-213) or any other HomeKit-enabled switch,
  • 2-way normally open or normally closed solenoid valve (100-240V AC).
