It sounds a loud siren and flashes a light on the sensor, is rated for 5 years on two AAA cells against 1.5 on the Shelly's CR123A, and is sealed to IP67. The Shelly Flood is the smarter device: it joins Wi-Fi with no gateway, works with Google Home, SmartThings and Home Assistant, supports automations, adds temperature and freeze alerts and carries a 2-year warranty against 1. The Govee needs its gateway and keeps its alerts in the Govee app, with no platform integrations. Choose the GoveeLife Water Sensor Alarm for audible, low-maintenance leak protection, and the Shelly Flood for leak and freeze data inside a smart home.

What the differences mean

Alarm on the sensor

The GoveeLife Water Sensor Alarm has a siren and a light, so anyone nearby hears the leak. The Shelly Flood has neither and depends on phone alerts or an automation to warn you.

Battery life

The GoveeLife Water Sensor Alarm is rated for 5 years on two AAA cells. The Shelly Flood is rated for 1.5 years on a CR123A that is not in the box, because Wi-Fi costs more power.

Smart home platforms

The Shelly Flood works with Google Home, SmartThings and Home Assistant and supports automations. The GoveeLife Water Sensor Alarm works with no platform and has no automations; its alerts stay in the Govee app.

Freeze alerts

The Shelly Flood measures temperature and sends temperature and freeze alerts. The GoveeLife Water Sensor Alarm detects water only.

Hub requirement

The Shelly Flood connects straight to 2.4 GHz Wi-Fi. The GoveeLife Water Sensor Alarm reports through Govee's gateway, which has to stay plugged in.

What owners say

Owners of both like how cheap each unit is to place near every water source. GoveeLife Water Sensor Alarm owners single out detection within seconds, an alarm heard from other floors, batteries that last and the option to mute the siren while phone alerts continue. Shelly Flood owners single out setup from a phone browser with no app, automatic discovery in Home Assistant and the temperature reading that comes with it. The complaints differ: Govee owners mention trouble finding the right gateway when it was not bundled and the odd faulty sensor, while Shelly owners mention Wi-Fi pairing that takes several attempts and sensors that fall off the network and need reconnecting.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
