Overview
A small wireless leak detector placed on the floor near common failure points. When water is detected, NOA sends an immediate push notification and can trigger a connected Smart Water Valve to shut off the main line.
Problem it solves
Slow, hidden leaks damage floors, cabinetry and neighboring units — often unnoticed for days. The Leak Sensor catches leaks the moment they start and enables automatic shut-off when paired with the NOA Smart Water Valve.
Recommended installation area
Under kitchen and bathroom sinks, behind toilets, next to washing machines and water heaters.
NOA app connection
Pairs to the NOA app during setup. Shows a live 'dry / wet / low-battery' status per sensor.
Hub requirement
No dedicated hub required for the base experience. Automation with the Smart Water Valve is handled inside the NOA app.
Warranty
12-month limited manufacturer warranty against defects.
