Water Leak Alarm
Engineered for versatility and reliability, this water detector features an IP65 waterproof rating, making it perfectly suited for damp environments. It requires no complex installation—simply place it flat on any hard or soft surface, such as floors or carpets, near potential leak sources like washing machines, water heaters, or dishwashers. Through the Z-Wave network, it can trigger associated devices; for instance, it can automatically command a smart water valve to turn off the water supply the moment a leak is detected.
