Best Smart Water Leak Detectors

These small devices, which connect to the internet, can be placed in areas of your home that are prone to leaks or flooding, such as exposed pipes, damp basements, water heaters, and washing machines. As soon as their sensors detect water, they send an alert to your smartphone, and sometimes sound a siren, so you can investigate quickly.

I recently put seven water leak detectors to the test in my home. The detectors come from Aqara, D-Link, Eve, Kidde, Moen, Swann, and X-Sense. Many of them are fairly inexpensive, with all but one model costing less than $100 and three detectors costing less than $50.
