It is also the cheaper of the two, needs no gateway, sends low battery alerts and carries a 2-year warranty against 1 year. The GoveeLife Water Leak Detector 2 is the better reviewed and the one you can hear, with a 100 dB alarm and a light on the sensor, IP66 sealing, a long-range LoRa gateway in the box and about 2 years per battery set against 1.5 years. It stays inside the Govee app, where it can still run automations. Choose the Shelly Flood for a connected smart home and freeze warnings, and the GoveeLife Water Leak Detector 2 for a loud standalone alarm.

What the differences mean

Alarm at the sensor

The GoveeLife Water Leak Detector 2 sounds 100 dB and flashes where the water is. The Shelly Flood is silent and relies on your phone or smart home to tell you.

Temperature

The Shelly Flood has a temperature sensor with general and freeze alerts, useful in a basement or laundry in winter. The GoveeLife Water Leak Detector 2 watches for water only.

Network and platforms

The Shelly Flood joins Wi-Fi directly and works with Google Home, SmartThings and Home Assistant. The GoveeLife Water Leak Detector 2 reports through its included LoRa gateway, which reaches far corners of a house, but stays inside the Govee app.

Battery

The GoveeLife Water Leak Detector 2 runs about 2 years on two AAA batteries. The Shelly Flood gets about 1.5 years from a CR123A that is not in the box, though it does send low battery alerts.

What owners say

Owners of both describe detection that reacts within seconds and sensors cheap enough to place near several water sources. GoveeLife Water Leak Detector 2 owners single out a guided setup, an alarm loud enough to hear across the house and real saves, a failed condensate line or a loose washer hose, while pointing out that the gateway has to stay plugged in and that nothing leaves the Govee app. Shelly Flood owners like configuring it from a phone browser with no app and Home Assistant finding it on its own, but they report a first Wi-Fi pairing that can take a few attempts and units that drop off the network and need reconnecting.
