Updated October 2026
Data from Amazon and official TP-Link and X-Sense sites.

It works with Google Home, runs automations in the Tapo app, is rated IP67 against IP66 and adds a light to its 90 dB alarm. The X-Sense Wi-Fi Water Leak Detector answers with a 5-year warranty against 1 year, a lower price and a direct 2.4 GHz Wi-Fi link, plus a louder 110 dB alarm and 4 bottom and 2 top probes, but its alerts stay in the X-Sense app, with Home Assistant only through a community integration. Both run on batteries rated for 3 years and detect water only. Pick the Tapo T300 if you have or will add a Tapo hub and want Google Home, and the X-Sense Wi-Fi Water Leak Detector for a simple, loud alarm with the longest warranty.

What the differences mean

Hub

The X-Sense Wi-Fi Water Leak Detector connects over 2.4 GHz Wi-Fi. The Tapo T300 talks Sub-1G to a Tapo hub and does nothing without one, which owners call the most common surprise.

Smart home platforms

The Tapo T300 works with Google Home, partially with Home Assistant, and supports automations. The X-Sense Wi-Fi Water Leak Detector works with none of Google Home, Alexa, Apple Home or SmartThings, reaches Home Assistant only through a community integration and has no automations.

Warranty

X-Sense covers the X-Sense Wi-Fi Water Leak Detector for 5 years; TP-Link covers the Tapo T300 for 1. For a sensor meant to sit untouched under a sink, that is a real difference.

Alarm

Both sound an alarm on the device: 110 dB on the X-Sense Wi-Fi Water Leak Detector and 90 dB on the Tapo T300. Only the Tapo also flashes a light.

Waterproofing

The Tapo T300 is IP67 and the X-Sense Wi-Fi Water Leak Detector IP66. Both handle wet floors; the Tapo is rated for immersion.

What owners say

Owners of both sensors say the same thing first: the alarm is loud and the alerts have caught real leaks, from water heaters to sump pumps. Tapo T300 owners single out quick setup in the Tapo app next to their Tapo and Kasa devices, months without a dropout and detection from both the top and bottom of the unit, and their complaints are the separate Tapo hub, sensor and hub versions that did not match outside the US and a small top drip probe. X-Sense Wi-Fi Water Leak Detector owners talk about easy activation, a slim shape that fits behind a toilet or under an appliance, low battery alerts and a detector that paid for itself on its first trigger, while noting that alerts never leave the X-Sense app and the printed manual is tiny.

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.
