The L Series smart water leak damage defense system responds to water alerts with an automatic shutoff response for simple water damage prevention. Professional installers can easily link the L5 Wi-Fi water leak shutoff valve with multiple Resideo Wi-Fi water leak and freeze detectors to create a water leak detection and defense system for whole home coverage. The detector senses water leaks, temperature changes and humidity, and sends an alert — either via the Resideo app or the device —when a leak is detected or when the temperature or humidity levels are outside a set range.
