How to choose

The YoLink sends app, email, and SMS alerts and can trigger YoLink sirens for audible alerts. Match the volume to how far the alarm must carry, and check whether alerts go to your phone.
Compare packs and batteries
Pack sizes run 6 sensors on the YoLink, GoveeLife, and Flood Buzz, and 3 sensors on the Blizonte. Battery life runs up to 5 years on the YoLink, GoveeLife, and Blizonte, and up to 3 years on the Flood Buzz. The Zircon runs on a 9V battery, and the Blizonte warns when its battery drops below 5%. Match pack size to the spots you want to cover.
Check alerts and placement
Alerts differ: the YoLink and GoveeLife send app, email, and SMS alerts, while the Flood Buzz, Zircon, and Blizonte sound alarms at the leak. The YoLink works without internet to trigger sirens or shutoff valves, and the GoveeLife gateway supports 2.4G Wi-Fi.
