It is also the lower priced and the far smaller of the pair, a disc 15 mm thick that fits under the tightest sink, and it runs 2 years on a CR2032. The Aeotec Water Sensor 7 Pro is a Z-Wave sensor for SmartThings and Home Assistant that answers with a probe on a cable, temperature and freeze alerts the Aqara lacks, and a 3 year ER14250 battery, but its body is only rated IP20. Neither has a siren or a light on the sensor, and neither works with Alexa or Google Home. Pick the Aqara Water Leak Sensor for an Aqara, Apple Home or Zigbee home, and the Aeotec Water Sensor 7 Pro for a Z-Wave home that also wants to watch pipes for freezing.

What the differences mean

Radio and hub

The Aeotec Water Sensor 7 Pro is Z-Wave and needs a Z-Wave hub; the Aqara Water Leak Sensor is Zigbee and works best with an Aqara hub. Pick the one that matches the hub you already own, because neither works without one.

Platforms

Both work with Home Assistant. Through an Aqara hub, the Aqara Water Leak Sensor also reaches Apple Home, SmartThings and Matter. The Aeotec Water Sensor 7 Pro works with SmartThings natively over Z-Wave, but not with Apple Home or Matter.

Temperature and freeze alerts

Only the Aeotec Water Sensor 7 Pro has a temperature sensor, so it can warn about a cold crawl space before a pipe bursts. The Aqara Water Leak Sensor reports water and low battery, nothing else.

Getting wet

The Aqara Water Leak Sensor is rated IP67 and owners describe it working fine when soaked. The Aeotec Water Sensor 7 Pro body is only IP20, and some owners saw its probe corrode in constantly damp spots, so its body should stay dry while the probe does the detecting.

Reach and battery

The Aeotec Water Sensor 7 Pro includes a sensor cable, so the probe can go into a drain pan while the body sits higher up, and its ER14250 is rated for 3 years. The Aqara Water Leak Sensor detects only where it sits, on a CR2032 rated for 2 years.

Which one to buy if

What owners say

Owners of both sensors say the same thing first: detection is fast and sensitive, even to a small amount of water, and both groups build automations on it, from shutting off a pump or a dehumidifier to routines on their hub. The complaints split by radio. Aeotec Water Sensor 7 Pro owners praise the probe on its cable and a battery nobody has had to replace, but describe a fiddly Z-Wave pairing that took factory resets on some hubs, and a few saw the probe corrode after months in a damp spot. Aqara Water Leak Sensor owners love how small it is and report two years or more on the original coin cell, while their warnings are about hubs: some Home Assistant users paired it directly without trouble, others found non-Aqara Zigbee hubs dropped it, and HomeKit or SmartThings households were caught off guard by the Aqara hub requirement.

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.
