Water Leak Sensors

Small battery sensors that sit on the floor where water shows up first — under sinks, behind the washer, next to the water heater — and alert your phone, hub or siren the moment they get wet.

  • Works with Zigbee and Z-Wave hubs or plain Wi-Fi
  • Loud local siren plus app alert
  • Cable probes for tight spots
