It sounds a 110 dB alarm against about 60 dB, is rated for 3 years on two AAA cells against 1.5 years, carries a 5-year warranty against 1, connects over Wi-Fi with no separate hub, and is the better reviewed and lower priced of the pair. The Meross Smart Water Leak Sensor is the smart home one: it works with Apple Home, SmartThings and Home Assistant through the Meross Smart Wi-Fi Hub, supports automations and is IP67 against IP66. Both detect water only. Choose the X-Sense Wi-Fi Water Leak Detector if you want a leak heard and a sensor that just works, and the Meross Smart Water Leak Sensor if leaks should trigger Apple Home automations.

What the differences mean

Alarm loudness

The X-Sense Wi-Fi Water Leak Detector sounds 110 dB, loud enough to hear from another room. The Meross Smart Water Leak Sensor manages about 60 dB, which owners say is too quiet to rely on, and neither has an alert light.

Smart home platforms

The Meross Smart Water Leak Sensor works with Apple Home, SmartThings and Home Assistant and supports automations. The X-Sense Wi-Fi Water Leak Detector reaches only Home Assistant, through a community integration, and has no automations.

Hub

The Meross Smart Water Leak Sensor talks Sub-1G to the Meross Smart Wi-Fi Hub, which owners say can drop offline. The X-Sense Wi-Fi Water Leak Detector connects over 2.4 GHz Wi-Fi.

Battery and warranty

The X-Sense Wi-Fi Water Leak Detector is rated for 3 years on two AAA cells with a 5-year warranty. The Meross Smart Water Leak Sensor is rated for 1.5 years on a CR123A with a 1-year warranty.

What owners say

Owners of both sensors report leaks caught early enough to avoid damage, and both groups like how easy the sensors are to pair and tuck beside an appliance. Meross Smart Water Leak Sensor owners single out seamless Apple Home integration, with sensors appearing on the Home dashboard and closing a solenoid valve through automations; their main complaint, and the most serious one, is a hub that goes offline and silently stops remote alerts until it is restarted, and some found the local alarm too quiet. X-Sense Wi-Fi Water Leak Detector owners talk about peace of mind after it flagged a sump pump failure or an appliance leak, an alarm loud enough to hear elsewhere in the house and low battery alerts, and note only that alerts stay in the X-Sense app and the manual is printed small.

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.
