It is sealed to IP67 where the Aeotec is only IP20, is rated for 2 years on a CR2032 against 1 year on a CR2, and through an Aqara hub reaches Google Home, Apple Home, SmartThings and Matter as well as Home Assistant. The Aeotec Water Leak Sensor keeps a real advantage: a temperature sensor with temperature and freeze alerts, and direct SmartThings support with no Aqara hub in between. Neither has a siren or light on the device, so both rely on the hub to warn you. Choose the Aqara Water Leak Sensor T1 for spots that can get soaked and broad platform reach, and the Aeotec Water Leak Sensor for a SmartThings home that also wants freeze warnings.

What the differences mean

Water protection

The Aqara Water Leak Sensor T1 is IP67 and survives sitting in water. The Aeotec Water Leak Sensor is IP20, meaning no real protection for the unit itself, so it is placed to detect nearby leaks rather than in a spot that floods.

Freeze alerts

The Aeotec Water Leak Sensor measures temperature and sends temperature and freeze alerts, handy near pipes in a cold basement. The Aqara Water Leak Sensor T1 detects water only.

Battery

The Aqara Water Leak Sensor T1 is rated for 2 years on one CR2032 coin cell. The Aeotec Water Leak Sensor is rated for 1 year on a CR2, a pricier cell to replace.

Smart home platforms

The Aeotec Water Leak Sensor works with SmartThings and Home Assistant. The Aqara Water Leak Sensor T1 works with Home Assistant directly and with Google Home, Apple Home, SmartThings and Matter through an Aqara hub.

Which one to buy if

What owners say

Aeotec Water Leak Sensor owners come back to build quality first, describing it as solid and well made next to cheaper Zigbee leak sensors. They report reactions within seconds to a puddle or a few drops, quick pairing with a SmartThings or Home Assistant hub by pulling a battery tab and scanning a code, and automations that close a smart shutoff valve when water appears. What they warn about is placement and upkeep: with an IP20 rating the sensor itself should not sit where it gets splashed or submerged, the CR2 battery costs more to replace than a coin cell, and a minority outside SmartThings or Home Assistant see it drop off the Zigbee network and need re-pairing.
