SAN JOSE, Calif., March 19, 2026 — THIRDREALITY today introduced the Smart Water Leak Sensor KM1, a Matter-enabled leak-detection system designed to help households identify water leaks early. The system combines a central controller with multiple wireless sensors for kitchens, bathrooms, basements and laundry areas.
As a Matter-enabled device over Wi-Fi, the KM1 is designed to work across a wide range of smart home platforms. It has been tested and verified with platforms such as Apple Home, Alexa, Home Assistant, and Homey, helping ensure a reliable and consistent user experience while keeping the flexibility that Matter is designed for.
Built with real homes in mind, the KM1 combines a central controller with multiple sensors to cover key risk areas like kitchens, bathrooms, basements, and laundry spaces. With a wireless range of up to 100 meters (328 ft) in open environments, the system can reliably cover most households without worrying about signal gaps.
The KM1 is designed for quick deployment. The controller comes pre-paired with three sensors, allowing users to set up protection in minutes. Once connected, the system begins monitoring immediately.
If water is detected, the controller triggers a 100 dB audible alarm—loud enough to be heard from other rooms or enclosed spaces like basements. At the same time, users can receive alerts through their connected smart home platform, whether they are at home or away. A physical switch on the controller also allows users to quickly mute the alarm when needed.
Designed for everyday use, each sensor runs on standard AAA batteries with a lifespan of up to three years, reducing maintenance. The system also supports over-the-air updates via the 3R-Installer app, allowing continuous improvements over time.
The THIRDREALITY Smart Water Leak Sensor KM1 is now available in North America at a retail price of $39.99, offering an accessible way for households to expand their home protection without adding complexity.
With the Smart Water Leak Sensor KM1, THIRDREALITY continues to expand its lineup of Matter-based smart home products—focusing on solutions that are easy to use, broadly compatible, and designed for real-world needs.
