What the differences mean

Freeze warnings

The YoLink Water Leak Sensor 4 reports low temperatures and sends freeze alerts. The X-Sense Wi-Fi Water Leak Detector has no temperature sensor, so it cannot warn before pipes freeze.

Connection

The X-Sense Wi-Fi Water Leak Detector connects over 2.4 GHz Wi-Fi. The YoLink Water Leak Sensor 4 uses LoRa to a YoLink hub, which reaches garages and outbuildings where Wi-Fi fades but has to be bought if you do not own one.

Smart home platforms

The YoLink Water Leak Sensor 4 works with Home Assistant, announces its alerts on Alexa through the YoLink skill and runs automations. The X-Sense Wi-Fi Water Leak Detector works only with Home Assistant through a community integration and supports no automations.

Battery and warranty

The YoLink Water Leak Sensor 4 is rated for 5 years on two AAA cells with a 2-year warranty. The X-Sense Wi-Fi Water Leak Detector is rated for 3 years on two AAA cells, but X-Sense backs it for 5 years.

Probes

The X-Sense Wi-Fi Water Leak Detector has 4 bottom and 2 top probes, so it catches drips from above as well as water on the floor.

Which one to buy if

What owners say

Owners of both detectors lead with the same story: a sump pump failure, a water heater or a washing machine hose caught before it flooded the floor, and an alarm loud enough to hear elsewhere in the house. YoLink Water Leak Sensor 4 owners single out range that reaches garages and outbuildings, a siren that still fires when the hub is offline, freeze warnings from the same device and Alexa announcements and IFTTT routines, while a few found the app confusing to set up. X-Sense Wi-Fi Water Leak Detector owners talk about easy activation, a slim housing that fits behind a toilet and low battery alerts backed by a long warranty; their caveats are alerts that stay in the X-Sense app and a setup manual printed very 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.
