The Zooz ZSE42 is a miniature Z-Wave Plus water sensor designed to slip into the tightest spots — under dishwashers, behind toilets, and beneath HVAC units. At 1.4 inches across, it's among the smallest flood sensors available. It pairs with any Z-Wave hub (SmartThings, Hubitat, Home Assistant) and reports in under a second, giving automated systems time to close shutoff valves before damage spreads.
