When it comes to preventing water leaks and unhealthy mold, Wally has you covered. Wally is a revolutionary water leak detection system that uses a patented sensor network and Hub to detect and alert you of water leaks as well as important changes in humidity and temperature. Wally got its name because it uses the existing wiring within the walls of your home as an antenna. Since the signal range permeates your entire home, not only is the signal strength never compromised, but also data transmission is no longer the dominant power consumer. Most sensor devices constantly send data via Bluetooth or Wi-Fi, resulting in short battery life. With Wally's unique patented technology, sensors are guaranteed to last 10+ years 5 times longer than typical in-home sensors.
