2026 verdict
Of these two silent Zigbee leak pucks, the Aqara Water Leak Sensor T1 is the tougher and longer-lasting one.
It is sealed to IP67 where the Aeotec is only IP20 and is rated for 2 years on a CR2032 against 1 year on a CR2. Through an Aqara hub, the Aqara Water Leak Sensor T1 also 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
- the sensor may end up sitting in water
The Aqara Water Leak Sensor T1 is IP67; the Aeotec is only IP20.
- you want freeze warnings from the same sensor
Only the Aeotec Water Leak Sensor has temperature and freeze alerts.
- your hub is SmartThings and you do not want an Aqara hub
The Aeotec Water Leak Sensor pairs with SmartThings directly; the Aqara reaches it through its own hub.
- your home runs on Apple Home or Matter through an Aqara hub
The Aqara Water Leak Sensor T1 reaches both that way; the Aeotec reaches neither.

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.
Frequently Asked Questions
Which is better overall: Aeotec Water Leak Sensor or Aqara Water Leak Sensor T1?
The Aqara Water Leak Sensor T1, for its IP67 rating, longer rated battery life and wider platform reach through an Aqara hub. The Aeotec Water Leak Sensor is the better pick if you want freeze alerts or direct SmartThings support.
Does the Aeotec Water Leak Sensor work with SmartThings?
Yes. The Aeotec Water Leak Sensor pairs directly with a SmartThings or Home Assistant Zigbee hub. The Aqara Water Leak Sensor T1 reaches SmartThings only through an Aqara hub.
Do they have an alarm on the sensor?
No. Neither the Aeotec Water Leak Sensor nor the Aqara Water Leak Sensor T1 has a sounder or light, so the alert comes from your hub, your phone or another device you automate.
Which one is waterproof?
The Aqara Water Leak Sensor T1, rated IP67. The Aeotec Water Leak Sensor is rated IP20 and should not be placed where it can be splashed or submerged.
Who should buy the Aeotec Water Leak Sensor?
SmartThings and Home Assistant users who want a well-built leak sensor that also warns about freezing temperatures near pipes.
Who should buy the Aqara Water Leak Sensor T1?
Aqara hub and Zigbee users who want a small, fully waterproof puck under dishwashers, sinks and toilets, tied into Apple Home, Google Home, Matter or Home Assistant.
