The Ecolink ZWave Plus Water/Flood and Freeze sensor works with Zwave or ZWave plus enabled smart home hubs and software to detect water leaks or temperatures that fall to around 5C. The water probe is on a 3 foot cable to allow the probe to be placed exactly where you want it, while the transmitter can be mounted on the wall for the best reception. Use the Z-Wave water sensor near sinks, toilets, hot water tanks, washing machines and other high risk areas. This sensor is certified compatible with SmartThings, VeraEdge, VeraPlus, VeraSecure, Vera Lite, Homeseer/Hometroller.
