    Product sell sheet for the Resideo Braukmann L1 Wi-Fi Water Leak and Freeze Detector — a battery-operated, hub-free water leak sensor with smartphone alerts.

    Overview

    Water damage can happen to anyone. The L1 Wi-Fi Water Leak and Freeze Detector is an easy upgrade for any customer, providing advanced leak awareness and freeze warnings without requiring a separate hub or base station.

    Key Features

    • Advanced leak awareness — alerts to leaks or frozen pipes via smartphone notifications, plus on-site alerts with LED lights and a 100 dBA alarm.
    • Quick setup — the battery-operated device installs near a water heater, washing machine, sink, or sump pump. The Resideo App guides Wi-Fi connection setup. No hub or base required.
    • Extended reach — includes a 5-ft cable that senses water along its entire length. Coverage can be extended to up to 500 ft by adding additional devices or extending sensor cables.
    • Reusable sensor cord — after detecting water, simply let the cable dry completely and plug it back in — it's ready to use again. Extra Sensor Cables can be kept on hand for quick swaps.
