Matter water sensor arrives
ThirdReality launched the Water Leak Sensor Kit KM1 as a native Matter water sensor option, filling a gap in Matter-certified leak detection with long-range detection built for seamless smart-home integration (matteralpha.com). This is important if you’re standardizing on Matter and need reliable local leak alerts without vendor lock-in (matteralpha.com).
ThirdReality is selling the Smart Water Leak Sensor KM1 in North America for $39.99, with product pages and Amazon listings live now. (prweb.com)) The retail kit ships with one KM1 controller and three pre‑bound water detectors, and the controller ships with a Type‑C power cable. (thirdreality.com)) The company says each detector runs on two AAA batteries with up to three years’ battery life, and the system supports over‑the‑air firmware updates via the 3R‑Installer app. (thirdreality.com)) The KM1 exposes Matter over Wi‑Fi for local integration with a Matter controller, while the satellite leak probes communicate to the central controller over a sub‑GHz link—review coverage identifies that sensor link as 433 MHz. (thirdreality.com)) ThirdReality and several retailers list the controller’s built‑in alarm at roughly 100 dB, while CES and some product pages also point to long‑range coverage (advertised in different places as ~80 meters and ~100 meters in open space). (thirdreality.com)) The kit is Matter‑certified and listed as compatible with Apple Home, Amazon Alexa, Home Assistant and Homey, and MatterDevices records the KM1 model number as 3RWLK01068M.
