Eufy Water and Freeze Sensor vs YoLink Water Leak Sensor 4

Full Smart Water Leak Sensors comparison in 2026

Updated October 2026
Data from Amazon and official Eufy and YoLink sites.
2026 verdict
Only an existing Eufy HomeBase argues for the other side: the YoLink Water Leak Sensor 4 is the better leak and freeze sensor, with a 105 dB siren on the puck, IP66 sealing and up to 5 years per battery set.

It is also the cheaper and better reviewed of the two, sends low battery and low temperature alerts, lights up on the sensor and carries a 2-year warranty against 1 year. The Eufy Water and Freeze Sensor matches it on the essentials, leak and freeze alerts and Home Assistant access, and pairs straight into the HomeBase that Eufy camera owners already have. Both need their own base, a YoLink hub or a Eufy HomeBase, and neither works with Google Home, Apple Home, SmartThings or Matter. Buy the YoLink Water Leak Sensor 4 unless your Eufy cameras already sit on a HomeBase, where the Eufy Water and Freeze Sensor saves you a second hub.

What the differences mean

Alarm on the sensor

The YoLink Water Leak Sensor 4 sounds 105 dB and flashes at the puck, and its owners report it does so even when the hub is offline. The Eufy Water and Freeze Sensor has no sound or light of its own and relies on the HomeBase and the app.

Battery life

The YoLink Water Leak Sensor 4 is rated for about 5 years on two AAA batteries and sends low battery alerts. The Eufy Water and Freeze Sensor is rated for 2 years on a CR123 cell, and low battery alerts are not documented for it.

Base you need

Neither connects to Wi-Fi directly. The YoLink Water Leak Sensor 4 needs a YoLink hub over LoRa, built for long range; the Eufy Water and Freeze Sensor needs a Eufy HomeBase. If you already own one of the two, that settles most of the cost.

Sealing and warranty

The YoLink Water Leak Sensor 4 is sealed to IP66 with a 2-year warranty; the Eufy Water and Freeze Sensor to IP65 with 1 year. Both are built to sit on a wet floor.

Which one to buy if

What owners say

Owners of both credit their sensor with fast, sensitive detection. YoLink Water Leak Sensor 4 owners tell of a burst water heater or washer hose caught in time, praise a siren that sounds even when the hub is offline, long range across large properties and years on one set of batteries, and their main complaint is a companion app that is confusing to configure at first. Eufy Water and Freeze Sensor owners single out the easy sync into an existing HomeBase and alerts from a couple of drops, but they complain that the HomeBase alarm sounds like the camera alarm, that pairing occasionally fails and that the base's recording schedule can delay water alerts.

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.
