Aqara Water Leak Sensor T1 vs Eufy Water and Freeze Sensor

Full Smart Water Leak Sensors comparison in 2026

Updated October 2026
Data from Amazon and official Aqara and Eufy sites.
2026 verdict
If the job is to warn you about a freezing pipe as well as a leak, the Eufy Water and Freeze Sensor is the better of these two water leak sensors.

Winner
Eufy Water and Freeze Sensor
$34.99
Buy on Amazon USACheck price
It wins on price, on owner rating and on coverage, since it senses temperature and freeze alongside water where the Aqara Water Leak Sensor T1 is water only. The Aqara Water Leak Sensor T1 still earns its place in a Zigbee home: it triggers at just 0.5 mm, is IP67 sealed so it survives the flood it reports, and reaches Apple Home, Google Home and Matter through an Aqara hub. The Eufy Water and Freeze Sensor instead needs a Eufy HomeBase and offers Home Assistant only through a community integration. Pick the Aqara Water Leak Sensor T1 for a Zigbee setup that wants a tough, low-profile puck, and the Eufy Water and Freeze Sensor when freeze protection is the point.

What the differences mean

Freeze detection

The Eufy Water and Freeze Sensor watches for freezing pipes and raises freeze-temperature alerts, which matters in a garage, attic or unheated basement. The Aqara Water Leak Sensor T1 is a water-only device with no temperature sensor and no freeze alerts.

Smart home path

The Aqara Water Leak Sensor T1 needs a Zigbee hub, reaches Apple Home, Google Home and Matter through an Aqara hub, and pairs with a SmartThings hub directly. The Eufy Water and Freeze Sensor needs a Eufy HomeBase and reaches Home Assistant only through a community integration.

Trigger depth and sealing

The Aqara Water Leak Sensor T1 reacts at 0.5 mm of water and carries an IP67 rating that covers submersion, so it keeps working through the leak it just reported. The Eufy Water and Freeze Sensor is IP65 and detects water where the disc sits.

Footprint

The Aqara Water Leak Sensor T1 is 50 x 50 x 15 mm and 18 g, small enough to tuck behind a toilet or under a dishwasher. The Eufy Water and Freeze Sensor is a larger 66 x 66 x 30 mm disc at 89 g, which suits an open floor or a utility room.

Alarm source

Neither device makes a sound on its own. The Aqara Water Leak Sensor T1 has the hub sound an alarm and notify your phone, while the Eufy Water and Freeze Sensor leaves it to the HomeBase and its shared tone.

Which one to buy if

What owners say

The Eufy Water and Freeze Sensor is the one with owner reviews behind it, and they describe the same two strengths: it catches even small amounts of water quickly and it pairs into the Eufy app in minutes. Owners site it at water heaters, sump pumps and washing machines, and several say they bought it only after a flood taught them to. The downsides they raise are consistent too. The HomeBase alarm uses the same loud tone as Eufy's security cameras, so a leak is easy to confuse with a break-in and some owners just disable the sound. Others hit pairing failures, or find the HomeBase recording schedule can delay when an alert actually arrives. For a sensor that only works inside the Eufy ecosystem, that ecosystem is what people talk about most.

Frequently Asked Questions

Which is better overall: the Aqara Water Leak Sensor T1 or the Eufy Water and Freeze Sensor?

The Eufy Water and Freeze Sensor, for a home that needs both leak and freeze warnings. It adds temperature sensing, freeze alerts and a lower price. The Aqara Water Leak Sensor T1 is the better fit for a Zigbee home that wants a tiny, fully waterproof puck.

What is the biggest difference between the Aqara Water Leak Sensor T1 and the Eufy Water and Freeze Sensor?

Freeze coverage. The Eufy Water and Freeze Sensor reports freeze risk as well as water, while the Aqara Water Leak Sensor T1 detects water only, with no temperature sensor or freeze alerts in its spec sheet.

Does the Aqara Water Leak Sensor T1 work without an Aqara hub?

It needs a Zigbee hub to work at all. An Aqara hub is required for the Apple Home, Google Home and Matter paths, while a SmartThings hub can pair it directly over Zigbee.

Which of these two is waterproof enough to survive a flood?

The Aqara Water Leak Sensor T1 is rated IP67, which covers temporary immersion. The Eufy Water and Freeze Sensor is IP65, splash resistant rather than submersible.

Who should buy the Aqara Water Leak Sensor T1?

A Zigbee household under an Aqara, SmartThings or Home Assistant hub that wants an inexpensive, tiny, IP67 sensor and does not need freeze warnings.

Who should buy the Eufy Water and Freeze Sensor?

Someone with a Eufy HomeBase who wants freeze protection for pipes in a cold space and prefers a single sensor that reports both hazards.
