YoLink Water Leak Sensor 1 Kit, 3 Sensors and Hub

YoLink Water Leak Sensor 1 is a three-sensor leak-monitoring kit with one hub for app, email, and SMS alerts. Its sensors communicate with the hub over LoRa, while the hub needs power and an internet connection for remote notifications. The sensors are silent, so they do not provide an audible alarm at the leak location.

At a glance

Three sensors and one hub are specified for coverage across several leak-prone locations.
The hub connects by Ethernet or 2.4 GHz Wi-Fi. Sensors communicate with it over LoRa rather than pairing individually to Wi-Fi.
The listing claims up to five years of battery life per sensor, with replaceable AAA batteries. Actual life varies with use, activity, and temperature.
Top and bottom probes are intended to detect drips and pooling water. The sensor housing is listed as IP68-rated for indoor use, not continuous submersion.

Pros and cons

Pros

App, email, and SMS alert options can notify you remotely when the hub is powered and online.
The claimed open-air radio range is up to 2034 feet, potentially useful for spread-out indoor sensor placement. Walls, metal, and placement can reduce range.
Control-D2D can let a paired sensor trigger compatible YoLink shutoff devices locally, without internet or hub power, when the devices remain powered and in range.

Cons

The sensors are silent and have no built-in siren, so an alert at the sensor itself is not provided.
Automatic water shutoff requires compatible hardware sold separately.

What to know before buying

Listing details to confirm

The hub must be powered and online for app, email, and SMS alerts. The listed radio range is an open-air maximum, not a guaranteed indoor distance. Sensors are for indoor use and should not remain submerged. The listing also gives conflicting sensor battery information: its specifications state that six AAA batteries are required, while the feature text says each of three sensors includes two installed, replaceable AAA batteries. Check the selected kit details.

Who is it for?

A good fit for

Homes needing remote leak alerts at multiple locations such as under sinks, near water heaters, or beside washing machines.
Buyers already using or planning to add compatible YoLink shutoff devices, with the understanding that shutoff hardware is separate.
Users who can place a powered hub within practical radio range of the sensors and keep it online for remote alerts.

Less suited to

Anyone who needs an audible alarm built into each sensor.
Installations requiring outdoor or continuous-submersion sensor use.
Buyers seeking automatic shutoff from the kit alone without purchasing compatible shutoff hardware.

Customer feedback reports easy setup, leak detection, and prompt app notifications, including a report of detecting a small drip under a sink. Some feedback mentions connectivity concerns involving wired internet, while the summary also says customers report no issues connecting to the hub. For buyers relying on remote alerts, the hub’s online connection matters. These reported experiences do not establish performance in every home.

Positive themes

Customers describe setup as easy.
Customers report leak detection and app notifications, including detection of a small drip.

Mixed feedback

Feedback is mixed on connectivity. Some mention problems with wired internet connections, while other reported experiences describe no trouble connecting to the hub.

Frequently asked questions

What is included in this kit?

The product title and feature text specify three Water Leak Sensor 1 units and one YoLink hub, four items total. The specifications separately describe six AAA batteries as required, while the feature text says the sensors include two installed batteries each, so verify the selected package details.

Does each sensor sound an alarm?

No. The Water Leak Sensor 1 is described as silent and without a built-in siren. It sends alerts through the hub instead.

Does the kit shut off water automatically?

Not by itself. A sensor can trigger compatible YoLink shutoff devices after pairing, but the shutoff hardware is sold separately.

What does the stated 2034-foot range mean?

That is the stated maximum in open air. Walls, metal, and device placement affect actual range indoors.

Can the sensors send remote alerts if the internet is down?

The listing says remote app, email, and SMS alerts use a powered, online hub. Separately paired compatible shutoff devices may support local Control-D2D operation without internet or hub power when they remain powered and in range.
