Aqara Water Leak Sensor T1 vs SwitchBot Water Leak Detector

Full Smart Water Leak Sensors comparison in 2026

Updated October 2026
Data from Amazon and official Aqara and SwitchBot sites.
2026 verdict
Buy the SwitchBot Water Leak Detector when you want Wi-Fi with a siren on the puck and no Zigbee hub in the path.
This water leak sensor also lists Bluetooth, a light, IP67, Google Home, Apple Home, SmartThings and Home Assistant, on two AAA cells rated for 2 years. The Aqara Water Leak Sensor T1 is the smaller Zigbee puck, 50 mm square and 18 g, IP67, triggering in the product notes at 0.5 mm of water, with Matter, Apple Home and Google Home only through an Aqara hub. It has no siren of its own. Choose the SwitchBot Water Leak Detector to hear the leak without a hub, and the Aqara Water Leak Sensor T1 when that hub is already Aqara and Matter has to be on the list.

What the differences mean

Siren on the sensor

The SwitchBot Water Leak Detector has an alarm and a light. The Aqara Water Leak Sensor T1 has neither. Its notes say the alarm comes from the hub, so a leak at the far end of the house stays quiet unless some other device is told to make noise. That is the difference you meet at night.

Wi-Fi versus a Zigbee hub

The SwitchBot Water Leak Detector joins 2.4 GHz Wi-Fi and Bluetooth directly. The Aqara Water Leak Sensor T1 has no Wi-Fi radio. It needs a Zigbee hub, and the HomeKit, Google Home and Matter paths specifically want an Aqara hub. SmartThings and Home Assistant are listed on the Aqara as well. If you do not already own that hub, it is part of the purchase.

Matter

Matter is listed on the Aqara Water Leak Sensor T1 with an Aqara hub required, which is why the integrations category leans its way. Matter is unsupported on the SwitchBot Water Leak Detector. Apple Home and Google Home are listed on both, directly on the SwitchBot and through the Aqara hub on the T1. Both mark Alexa unsupported.

Size and the trip point

The Aqara Water Leak Sensor T1 is 50 x 50 x 15 mm and 18 g, small enough to disappear under a dishwasher, and the notes say it reacts at 0.5 mm of water. The SwitchBot Water Leak Detector is larger, at 29 x 32 x 78 mm and 109 g. Both are IP67, both are rated for about 2 years, and neither includes a probe cable. The Aqara uses one CR2032. The SwitchBot uses two AAA cells.

What owners say

Owners of the SwitchBot Water Leak Detector keep coming back to how little hardware the setup needs: batteries in, onto Wi-Fi in a few minutes, no separate hub to configure. Several credit it with a real save while they were away, a flooded basement or a failing washer hose, and they like contacts on the top and the bottom that react to a small amount of water. The complaints are placement and noise. With no probe cable, water that pools just outside the contacts can be missed. A few found the first Wi-Fi or HomeKit pair fiddly, and the onboard alarm is easier to lose from another room than the spec line "has a siren" suggests.
