It is an IP67 leak puck that talks to Google Home and Alexa through a Tapo hub, with a local siren and light. The Moen Smart Leak Detector still wins on connectivity, sensors and alerts by joining Wi-Fi directly and adding temperature plus freeze coverage. Choose the Tapo T300 for a cheaper leak-only hub sensor; choose the Moen Smart Leak Detector if you want freeze alerts without buying a Tapo hub.
