How to choose
Alarm volume first
Alarm volume decides whether you hear a leak from another room: 120 dB for the Topvico, 105 dB for the GoveeLife and YoLink, 100 dB for the winees and up to 95 dB for the Flood Buzz. The GoveeLife adjusts in 4 levels through the app and the winees in 3 levels, so check whether you want to tune the volume after setup.
Range and remote alerts
Range matters when the sensor sits far from the hub: the YoLink reaches up to 2034 ft and the GoveeLife up to 1804 ft, the GoveeLife even through 5 dense walls. For alerts away from home, the GoveeLife, YoLink and winees send app alerts, and the GoveeLife and winees add SMS and email. The Flood Buzz and Topvico sound their alarms at the leak itself.
Placement and power
Place sensors where water first appears: near water heaters, under sinks, by sump pumps and at low points on the floor. Battery life runs 5 years for the GoveeLife and up to 2 years of standby for the Topvico, while the Flood Buzz seals its battery for up to 3 years of active life. Check whether you want replaceable batteries before you buy.
