Meross Smart Water Leak Sensor MS405

Sensitive and reliable probes on both the top and the bottom of the leak sensor ensure no leak escapes notice—whether it’s slow drips or sudden pipe bursts. Never miss an alert with our 100dB dual alarm system (sensor and hub), even in heavy sleep. With the automation feature, you can also set color-coded alerts—like red lights—to notice leaks immediately.

Enjoy 24/7 peace of mind, anywhere—receive real-time leak alerts via app notifications. All incidents are logged for 2 years with free timeline reviews and exportable records in the Meross app, perfect for insurance claims or maintenance tracking.

Compatible with Apple Home, Alexa, Google Assistant, and SmartThings, it is easy to integrate the leak sensor into your smart home systems. Built to endure with an IP66-rated waterproof shell that survives leaks and floods. Powered by 2 AAA batteries (included and replaceable) with a life expectancy of over 3 years.

With a 100-meter transmission range, the Meross hub with SubG 433 MHz wireless technology has stronger and more stable signal transmission than WiFi and ZigBee/thread range. The leak sensor can effectively monitor water leaks in cellars, basements, laundry rooms, or under-sink installations.
