Water leaks can strike when you least expect them.

A burst pipe or leaky water heater in the basement, a drip under the sink, or an overflowing washer. Help safeguard your home with the Wi-Fi Water Leak Sensor Kit (SW-A11KT), your 24/7 watchdog that helps alerts you when a leak is detected. Set it up in minutes for whole-home coverage and enjoy peace of mind knowing it can help you catch small leaks before they become expensive disasters.

Don't Wait Until It's Too Late!

A small leak can quickly turn into a big, costly mess. Be proactive and help prevent water damage before it starts.

Multi-Alert System

When a leak is detected, an ear-splitting 100dB alarm and flashing LED strobe on the master unit will sound a warning, even if you’re asleep or don’t have your phone on hand. Simultaneously, you’ll get an alert on your phone, so you can respond whether you’re in the next room or on vacation. And for even more peace-of-mind, connect the system to your Google Assistant speaker or display and have it shout a warning when water is detected. No more creeping puddles turning into major flooding – you’ll catch it at the first sign of trouble.

Expands to Monitor up to 17 Locations

With one master unit and support for up to 16 wireless sensor pods, you can monitor leaks in up to 17 critical spots throughout your home. From water heaters and laundry rooms to basements, kitchens, and bathrooms—simply place a sensor wherever trouble might strike. As your needs grow or change, it’s easy to add or reposition sensors for total peace of mind.

Don’t let its small size fool you

The Master Plug-in Smart Wi-Fi Water Leak Sensor (SW-A1) packs a strobe, 100dB siren, mute/reset button, and Bluetooth into a footprint that only covers a single power socket. A 1.5 ft cable detects water along its length, plus a 3ft extension for flexible placement.

No Outlet? No Problem!

The Battery-powered Remote Water Sensing Pod (SW-A2), with its sub-GHz link, stays connected even in far corners. Compact and water-resistant, it slips under appliances or into tight spaces—perfect for areas without power outlets.

From busy households to frequent travelers, this smart water sensor helps you avoid coming home to a soaked living room or waking up to a flooded basement. Receive mobile alerts and act fast, wherever you are.
