Aqara Water Leak Sensor vs Eve Water Guard

Full Smart Water Leak Sensors comparison in 2026

Updated October 2026
Data from Amazon and official Aqara and Eve sites.
2026 verdict
Hearing the alarm from another room matters, and the Eve Water Guard is the one of these two leak sensors with its own siren and light.
Its sensing cable watches a whole stretch of floor rather than one spot, it plugs into the wall so there is no battery to replace, and it joins Apple Home natively over Thread or Bluetooth. The Aqara Water Leak Sensor is the small, battery-powered alternative: an IP67 puck that runs about 2 years on a CR2032, sends low battery alerts, works with Home Assistant and reaches Apple Home, SmartThings and Matter through an Aqara Hub. Neither works with Alexa or Google Home. Choose the Eve Water Guard to cover a kitchen or laundry run in an Apple Home, and the Aqara Water Leak Sensor to put small sensors under many sinks in an Aqara or Zigbee home.

What the differences mean

Local alarm

The Eve Water Guard sounds a siren and lights up. The Aqara Water Leak Sensor is silent, so the hub or the app has to tell you.

Coverage

The Eve senses along its cable, so one unit covers a long run behind appliances. The Aqara detects water only where the puck sits.

Power

The Eve Water Guard needs a wall outlet. The Aqara Water Leak Sensor runs about 2 years on a coin cell and warns when it is low, so it goes anywhere.

Apple Home path

The Eve joins Apple Home directly over Thread or Bluetooth. The Aqara reaches Apple Home, SmartThings and Matter only through an Aqara Hub, and works with Home Assistant as does the Eve.

What owners say

Owners of both credit them with catching real leaks. Aqara Water Leak Sensor owners single out an alarm that fires within a second of contact, years on the original coin cell and a puck small enough for any gap, and use it in automations; they warn that the hub requirement surprises some and that non-Aqara Zigbee hubs pair inconsistently. Eve Water Guard owners describe setup straight into the Home app with no account, the siren and light going off alongside notifications, and one cable watching a full row of appliances. They mention the price, the need for an outlet and a fabric cable that has to absorb a little water before it triggers, and a few had units stop detecting.

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.
