Protect your home from flooding with the Meross smart water leak sensor, featuring dual detection from both the top and bottom, an instant 100 dB alarm, and real-time push notifications to the app. Thanks to its compact size and IP66 rating, it’s ideal for placing under a sink, near a washing machine, or by a boiler, and it integrates easily into your smart home (Apple Home, Google Home, Alexa, SmartThings).
The Meross water leak sensor is designed to detect even small leaks early and help minimize property damage. With sensors located on the top and bottom, it can recognize both dripping water and liquid pooling on the floor.
When a leak is detected, a loud 100 dB alert sounds (on the sensor and the hub) and you will also receive a phone notification in the Meross app. You can also create automations, such as changing the color of smart lighting when a leak is detected.
