## Features

- Hassle-free setup and fit: very easy to install, just place it anywhere you like. Compact design and optional small size allow you to install the leak sensor in your kitchen, basement, laundry room, or any other flat surface you want to monitor leaks. We recommend placing the sensor near the washing machine, water heater, sink and dishwasher
- Instant Alarm: When the leak sensor setup successfully, the third-reality app will push the app and free email notifications, and the sensor will sound alarm. The leakage sensor can also be used when the internet is off. With a large 120dB alarm, it is large enough to leak in basement or home stairs
- APP FUNCTION: On the detailed page of the device, the Third Reality APP displays battery level, real-time status of the sensor, history view, and more
- 3 YEARS LONG BATTERY LIFE: The leakage sensor uses 2 AAA 1.5V alkaline batteries, easy to replace the battery
- Friendly for Apartment and Hotel Manager: The leakage sensor connected to a third-reality hub / smart speaker can be monitored not only from the third reality app, but also from the 3R-Protect Manager APP For more information on the 3R-Protect Manager APP, please visit the "Leak Sensor Kit" detail page
- Smart Assistant Support: Enabled by Smart Bridge MZ1 (sold separately) and integrates with Apple HomeKit and Google Home for easy control and monitoring. It also supports software OTA (Over the Air) update
