Buy on Amazon USA
The Moen Smart Leak Detector adds temperature, humidity and freeze alerts to its leak detection, ships a 48-inch remote sensing cable, is IP67, and sounds a 51 dB alarm with a blinking LED. The Aeotec Water Leak Sensor counters with the higher owner rating, a cheaper position and cleaner integration with Samsung SmartThings and Home Assistant, plus a temperature and freeze sensor of its own. The Aeotec Water Leak Sensor is the one held back by an IP20 rating, so it has to stay away from splashes. Choose the Moen Smart Leak Detector for a basement, sump pit or crawl space where the cable and the local alarm pay off, and the Aeotec Water Leak Sensor for a SmartThings or Home Assistant home that wants a well-built indoor puck at a lower price.

What the differences mean

Weather protection

The Moen Smart Leak Detector is IP67, so it tolerates a splash by the sump pump. The Aeotec Water Leak Sensor is IP20, which means it should detect water nearby rather than be exposed to it.

Remote sensing

The Moen Smart Leak Detector includes a 48-inch remote sensing disc for a sump pit or a gap behind an appliance. The Aeotec Water Leak Sensor has no cable and detects only at its own contacts.

Alerts and sensing

The Moen Smart Leak Detector reports temperature and humidity and sends freeze alerts, with an on-device alarm and light. The Aeotec Water Leak Sensor also senses temperature and warns of freezing, but has no sound or light of its own.

Smart home fit

The Aeotec Water Leak Sensor pairs with Samsung SmartThings and Home Assistant, which is more platform support than the Moen Smart Leak Detector, whose Home Assistant support is only partial and which lacks SmartThings and HomeKit.

Battery

The Moen Smart Leak Detector is rated about two years on a CR123A. The Aeotec Water Leak Sensor uses a CR2 rated around one year, a pricier cell to replace.

What owners say

Moen Smart Leak Detector owners who get through setup describe an accurate sensor that caught leaks near sump pumps, water softeners and washer hoses, and they like watching basement temperature and humidity and getting text, email and push alerts. The dominant complaint is setup itself: missing or unclear pairing steps, an app that loops, and units arriving with the battery's insulating tab partly in place so the cell is already drained. Aeotec Water Leak Sensor owners praise build quality and an almost instant reaction to small amounts of water, plus easy pairing with SmartThings and Home Assistant and the temperature and freeze bonus; a minority outside those hubs report the sensor dropping off Zigbee and needing a re-pair.

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.

Frequently Asked Questions

Which is better overall: Aeotec Water Leak Sensor or Moen Smart Leak Detector?

The Moen Smart Leak Detector is the better overall water leak sensor, winning on weather resistance, battery life, on-device alert sound and on-device alert light. The Aeotec Water Leak Sensor wins on price and owner rating.

Does the Aeotec Water Leak Sensor need a hub?

Yes. The Aeotec Water Leak Sensor is Zigbee and needs a hub, working with Samsung SmartThings or Home Assistant. The Moen Smart Leak Detector joins 2.4 GHz Wi-Fi directly.

Which sensor is waterproof?

The Moen Smart Leak Detector is IP67, so a splash is fine. The Aeotec Water Leak Sensor is IP20 and should sit beside a leak rather than in it.

Do both sensors warn about freezing pipes?

Yes. Both include temperature sensing and freeze alerts, so near a pipe either can warn before it freezes. Only the Moen Smart Leak Detector adds humidity readings and a local alarm.

Who should buy the Moen Smart Leak Detector?

Buy the Moen Smart Leak Detector for hub-free IP67 Wi-Fi leak and freeze alerts with a local siren, an LED, a 48-inch sensing cable and a two-year battery.

Who should buy the Aeotec Water Leak Sensor?

Buy the Aeotec Water Leak Sensor if you want a cheaper Zigbee leak-and-freeze sensor for a SmartThings or Home Assistant home, placed away from direct water.
