The Best Smart Water Leak Detectors

The Flo by Moen Smart Water Leak Detector is a reliable gadget to help protect your home from water damage. Flo by Moen's Smart Water Leak Detector is the very best smart water leak detector we've ever tested, beating out our previous No. 1 pick, the Honeywell Home Water Leak Detector. While the two detectors are comparable, Moen is the more affordable of the two and, most of all, we were impressed by the near-instantaneous alerts (an imperative function of a smart leak detector) the Moen leak sensor sent to both of our iOS and Android devices, as well as via email. The Flo by Moen Smart Water Leak Detector passed all of our tests with flying colors and even continued to function after being submerged in water during our final round of testing. When a leak is detected, the sensor begins playing an alarm sound and flashes red, in addition to sending timely alerts in a matter of seconds. However, what it lacks in voice-control capabilities, it makes up for with a beautifully designed app full of useful data insights. The sensor also keeps track of the temperature and humidity within your home, which can help with moisture control.
