The Aqara Water Leak Sensor T1 is the smaller, cheaper and more widely integrated option, triggering at just 0.5 mm and reaching HomeKit, Google Home and Matter through an Aqara hub, but it needs a hub and stays silent by itself. Choose the Moen for a hub-free sensor with local alerts and the Aqara for an inexpensive Zigbee point under a dishwasher or sink.

What the differences mean

Sensors

The Moen Smart Leak Detector adds temperature and humidity sensing and freeze alerts on top of water detection. The Aqara Water Leak Sensor T1 is a water-only detector.

Local alarm

The Moen Smart Leak Detector has a 51 dB buzzer and an alert light. The Aqara Water Leak Sensor T1 has neither, so the alarm comes from the hub.

Hub

The Aqara Water Leak Sensor T1 needs a Zigbee hub, and an Aqara hub for the HomeKit, Google Home and Matter paths. The Moen Smart Leak Detector joins 2.4 GHz Wi-Fi on its own.

Size

The Aqara Water Leak Sensor T1 is 50 x 50 x 15 mm and 18 g, small enough to tuck under a dishwasher. The Moen Smart Leak Detector is larger at 67 x 38 x 83 mm.

Remote probe

The Moen Smart Leak Detector includes a 48-inch remote sensing disc. The Aqara Water Leak Sensor T1 has no cable and detects water where it sits.

Battery

The Moen Smart Leak Detector uses a CR123A rated for about two years. The Aqara Water Leak Sensor T1 uses a CR2032 rated for over two years.

What owners say

Owners of the Moen Smart Leak Detector say the device does its core job once it is online, catching water near sump pumps and appliance hoses before it spreads, and they value the remote sensing disc for tight spots and the temperature and humidity readout. The complaints are consistent: a setup process many found frustrating, pairing instructions that were missing or unclear, an app that loops or fails to connect, and units that arrived with the insulating battery tab not fully removed so the cell was already partly drained. Several find the 51 dB alarm quiet and rely on phone notifications, and some note that Home Assistant support is only partial.
