How to choose
Local alarms versus app alerts
A local alarm sounds at the leak, while an app alert reaches your phone away from home. The Flood Buzz sounds a 95 dB alarm at the leak with no app. The GoveeLife sends app, SMS and email alerts, the YoLink sends app alerts, and the Moen app sends alerts and can shut off water. Choose a local alarm for one room, and app alerts when you want to know while away.
Range and hub requirements
Range is how far a sensor signal travels to its hub or gateway. The GoveeLife reaches up to 1804 feet through its gateway, and the YoLink reaches up to 2034 feet through its hub. The YoLink hub is sold separately, so check hub ownership before choosing. The GoveeLife gateway supports 2.4G Wi-Fi only.
Shutoff versus detection only
Detection tells you about a leak, while shutoff stops the water. The Moen Flo installs on the main water line, monitors flow, pressure and temperature, and shuts off water when it finds a leak. The other picks are sensors and alarms that alert you to leaks at the spot. Choose shutoff when you want water stopped automatically, and a sensor when you want an alert at one spot.
