Protect your home from water damage with the Meross MS400 sensor. When a leak is detected, it sends instant alerts to your phone and triggers a loud acoustic alarm ~60 dB. It’s compatible with Apple HomeKit and Samsung SmartThings, offers IP67 water resistance, and up to 18 months of battery life. A Meross MSH300 hub is required for operation (not included).
The Meross MS400 is a reliable smart water leak sensor for kitchens, bathrooms, utility rooms, and basements. When liquids are detected, it reacts immediately—activating a sound alarm and sending a push notification so you can act quickly and minimize damage. You can also view an event history in the Meross app.
Thanks to its IP67 rating, it’s ideal for damp environments, while low power consumption provides up to 18 months of operation on a replaceable CR123A battery.
