Updated October 2026
Data from Amazon and official Aeotec and Aqara sites.

It measures temperature, sends freeze alerts and is rated for about 3 years on its ER14250 cell, against about 2 years on the Aqara's CR2032. The Aqara Water Leak Sensor T1 wins on sealing and platform reach: it is IP67 against IP20, and it adds Google Home, Apple Home and Matter through an Aqara Hub on top of the SmartThings and Home Assistant support both share. Neither has a siren or light, so alerts come from the hub either way, and the Aeotec needs Z-Wave where the Aqara needs Zigbee. Choose the Aeotec Water Sensor 7 Pro for water heaters and pipes on a Z-Wave network, and the Aqara Water Leak Sensor T1 for a Zigbee home or a spot that could end up underwater.

What the differences mean

Temperature and freeze alerts

The Aeotec Water Sensor 7 Pro measures temperature and warns about freezing pipes. The Aqara Water Leak Sensor T1 detects water only.

Probe cable

The Aeotec comes with a sensor cable, so the body can sit dry while the probe goes into a drip pan or behind a heater. The Aqara T1 detects water where it sits.

Sealing

The Aqara Water Leak Sensor T1 is IP67 and survives sitting in water. The Aeotec Water Sensor 7 Pro is IP20, meant to stay dry while its probe does the sensing.

Radio and platforms

The Aeotec is Z-Wave; the Aqara is Zigbee. Both work with SmartThings and Home Assistant, and the Aqara adds Google Home, Apple Home and Matter through an Aqara Hub.

What owners say

Aeotec Water Sensor 7 Pro owners describe sensitive, accurate detection that catches small amounts of moisture and a probe cable that is more flexible than sensors reading only the floor under them. They find it works smoothly with Home Assistant and SmartThings, drive automations with it such as cutting power to a dehumidifier, and nobody complains about the battery. The friction is elsewhere: it needs a Z-Wave hub, something several say was not obvious before buying, pairing on some hubs takes a reset and a second attempt, and a few owners saw the probe corrode after months in wet placements.
