Data from the official Eufy and YoLink sites.
2026 verdict
An IP68 shell and years of battery life decide this one: the YoLink Water Leak Sensor 1 outpoints the Eufy Water and Freeze Sensor for a set-and-forget install, adding a status light the Eufy lacks.
The YoLink Water Leak Sensor 1 runs up to five years on two AAA batteries and reaches across a house over LoRa through a YoLink hub, with free app, email and text alerts and a two-year warranty. The Eufy Water and Freeze Sensor is sensitive enough to catch a couple of drops, pairs in a snap with a Eufy HomeBase, adds freeze-temperature alerts, and can sound an alarm from the base, but it is only IP65 and has no Wi-Fi, Bluetooth or Zigbee radio of its own. Pick the YoLink Water Leak Sensor 1 for damp basements, sump pits and a growing network of sensors, and the Eufy Water and Freeze Sensor if you already run a Eufy HomeBase and want its audible alarm nearby.

What the differences mean
What it senses
The Eufy Water and Freeze Sensor detects water and raises freeze-temperature alerts, which is what makes it a fit under a sink on an outside wall or in a cold utility space. The YoLink Water Leak Sensor 1 detects water only, so freeze protection there needs a different YoLink model.
The bridge it needs
The Eufy Water and Freeze Sensor reports only through a Eufy HomeBase, with no radio of its own. The YoLink Water Leak Sensor 1 reports over LoRa through a YoLink hub. Both need their brand's hub, and which one you already own decides the extra cost.
Weather rating and battery
The YoLink Water Leak Sensor 1 is IP68 and rated for up to five years on two AAA cells. The Eufy Water and Freeze Sensor is IP65 and rated for two years on a CR123. The YoLink is the tougher and longer-lasting unit, which is what makes it the set-and-forget pick.
Local alarm
The Eufy Water and Freeze Sensor can sound an alarm from the HomeBase, so someone in the house hears the alert, and it has a status light. The YoLink Water Leak Sensor 1 is silent apart from its status light, so an audible warning means adding a YoLink siren or SpeakerHub.
Platform support
Both work with Home Assistant, the Eufy through the eufy Security integration. The YoLink Water Leak Sensor 1 also supports IFTTT. Neither supports Apple Home, Google Home, SmartThings or Matter.
Warranty
The YoLink Water Leak Sensor 1 carries a two-year warranty and the Eufy Water and Freeze Sensor one year. For a sensor left out of sight for years, the extra cover belongs to the YoLink.
Which one to buy if
- you run a Eufy HomeBase and want an audible alarm nearby
The Eufy Water and Freeze Sensor can sound an alert from the HomeBase in addition to phone notifications.
- the sensor sits somewhere damp or could get splashed
The IP68 YoLink Water Leak Sensor 1 tolerates being soaked, where the Eufy is only IP65.
- you want freeze warnings for a pipe outdoors or in an unheated room
The Eufy Water and Freeze Sensor raises freeze-temperature alerts, which the YoLink Water Leak Sensor 1 cannot.
- you are building a larger set of sensors over time
One YoLink hub scales to hundreds of sensors, so each additional unit stays cheap.
- you want the longest battery life with the least attention
The YoLink Water Leak Sensor 1 is rated for up to five years against two for the Eufy.

What owners say
Owners of both sensors highlight the same strength, detection sensitive enough to catch a small amount of water fast. Eufy Water and Freeze Sensor owners call setup simple, a QR code or a sync tap, and like that alerts arrive both as phone notifications and, optionally, as an alarm from the HomeBase, which gives them peace of mind while traveling. They also value the dedicated freeze alert. Their complaints are specific: the HomeBase alarm shares the same tone as Eufy's cameras, so a leak is hard to tell from a break-in, several report pairing failures or a HomeBase recording schedule that delays alerts, and some want general temperature readings it does not provide. YoLink Water Leak Sensor 1 owners talk about range, with units staying connected from attics, basements and cottages where Wi-Fi sensors drop, and about speed, with test drips arriving within seconds by app, email and text and no subscription. They prize pairing it to a YoLink shutoff valve so a leak closes the main automatically, and they accept that the sensor is silent and needs a hub.
Frequently Asked Questions
Which is better overall: the Eufy Water and Freeze Sensor or the YoLink Water Leak Sensor 1?
For a damp, far-flung or long-life install, the YoLink Water Leak Sensor 1 wins, with IP68 sealing, up to five years of battery and a two-year warranty. The Eufy Water and Freeze Sensor is the better fit inside a Eufy home, where it adds freeze alerts and an audible alarm from the HomeBase.
What is the biggest difference between the Eufy Water and Freeze Sensor and the YoLink Water Leak Sensor 1?
Sensing versus sealing. The Eufy Water and Freeze Sensor reads water and freezing and can sound the HomeBase alarm, while the YoLink Water Leak Sensor 1 is a water-only LoRa sensor that is IP68 rated and runs up to five years on a charge.
Do these sensors work without their hub?
No. The Eufy Water and Freeze Sensor needs a Eufy HomeBase, and the YoLink Water Leak Sensor 1 needs a YoLink hub. Neither has a Wi-Fi, Bluetooth, Zigbee or Z-Wave radio of its own, so each is an add-on to its own ecosystem.
Which one warns about freezing pipes?
The Eufy Water and Freeze Sensor, which raises freeze-temperature alerts for pipes in cold spaces. The YoLink Water Leak Sensor 1 senses water only, so it offers no freeze warning at all.
Which sensor has the longer battery life?
The YoLink Water Leak Sensor 1, rated for up to five years on two AAA batteries, against two years on a CR123 for the Eufy Water and Freeze Sensor. Both are battery sensors, but the YoLink needs attention far less often.
Who should buy the Eufy Water and Freeze Sensor, and who should buy the YoLink Water Leak Sensor 1?
Buy the Eufy Water and Freeze Sensor if you already run a Eufy HomeBase and want freeze alerts plus an alarm from the base. Buy the YoLink Water Leak Sensor 1 for waterproof peace of mind in a basement or sump pit, or when you plan to add more sensors on one long-range hub.
