YoLink Water Leak Starter Kit: Hub + 2 Leak Sensor 4 (105 dB Siren), LoRa Long-Range, App/SMS/Email Alerts, D2D Offline, 2 AAA Up to 5-Year Battery, Compatible with Alexa/IFTTT/Home Assistant

I bought this leak starter kit after dealing with a small leak under the sink that turned into a big cleanup job with a new cabinet...lol. I wanted something simple and reliable this time, and so far this system has been exactly that. Setup was super easy. I plugged the hub into my router, opened the app, and it basically did the rest. Each sensor paired with one button press. I had everything installed in maybe 10–15 minutes for entire house. What I like most is that these don’t depend on Wi-Fi. I’ve got one sensor tucked behind a toilet, another under the kitchen sink, and even one in a spot where my Wi-Fi normally dies... and every sensor still connects with no issues. I tested all four sensors with a damp paper towel, and they alerted instantly. I get notifications on my phone and email, which is great for when I’m not home. A big plus for me is the battery life. These use simple AAA batteries, but they’re supposed to last years, not months. And the app actually shows the battery level for each sensor, so you’re not guessing. It’s nice to know you won’t get blindsided by a dead sensor right when you need it. The sensors feel solid and the app is straightforward. Honestly, this setup has already given me more peace of mind than anything else I’ve tried.

This is a great product! RARELY, almost never, do I submit product reviews. However, I purchased the YoLink kit to monitor the home while I am away for an extended period. I received an alert on a water leak to my 2nd floor HVAC unit, and was able to quickly mitigate the issue. I just bought a second kit to monitor a second home. Simple, easy, and effective!

Really happy with the YoLink Water Leak Starter Kit! I’ve been using this setup for more than 6 months now and couldn’t be happier with the results. The real-time alerts through the app provide great peace of mind, especially when I’m away from home. On top of that, the device itself sounds a loud alarm when it detects a leak, so you’re still alerted even if you miss the app notification. Setup was easy and it has been working reliably since day one. Highly recommended for anyone looking to protect their home from water damage.

The YoLink Water Leak Starter Kit (Hub + 4 Sensors) is a top-tier choice for reliable, long-range flood protection. Core Benefits Extreme Range: Uses LoRa technology to maintain a connection up to 1/4 mile away, making it perfect for basements or detached garages where Wi-Fi fails. Offline Reliability: Devices can pair directly (Control-D2D), meaning the sensors can trigger a siren or shut-off valve even if your Wi-Fi or internet goes down. Battery Life: Sensors typically last 5+ years on two AAA batteries, significantly outperforming competitors. Easy Setup: Features "Scan & Play" QR code integration via the app for near-instant pairing. Key Features Sensor 4 Upgrades: Includes a built-in 105dB alarm on the sensor itself and a freeze warning alert. Notifications: Supports push alerts, emails, and limited free SMS; integrates well with Alexa, IFTTT, and Home Assistant. Build Quality: Sensors are IP66-rated waterproof, so they continue to function even while submerged.

The YoLink Smart Home Water Leak Starter Kit is the ultimate peace-of-mind purchase for every homeowner. The system uses powerful LoRa technology, giving you an industry-leading 1/4-mile range so sensors placed in basements, under sinks, or in detached garages will always connect. The moment a leak is detected, you get instant SMS/Text, email, and app alerts, ensuring you are notified whether you're at work or out of town. Best of all, it keeps working—and sending alerts—even during a Wi-Fi or power outage, making it the most reliable protection against water damage. My only issue was that the app gives you a free monthly limit on the text alert, after that, the app will require a subscription.

I bought these sensors, for some peace of mind. I wanted to buy ones that had long range, and as I have heard from other reviews and articles, this LoRa technology promises, exactly that. The hub was easy to add to the app, and then leak sensors themselves were even easier to add; all I had to do was push a button at the bottom, and they were immediately discovered by the hub. From there, it was relatively simple to add them into Home Assistant. Although this took a couple of tries. So far, in a couple of weeks that I have owned them, connectivity has remained rock solid. If this continues to be the case, I think I am going to splurge and buy their local hub. Although it costs $200, it allows for 100% local control and management of the sensors, without the need for the cloud, which I really appreciate, as I try to make sure that all my smart devices are locally controlled. All in all, I find this sensors to be a good purchase, and their reliability so far gives me peace of mind that they will work if and when I ever need them to.

Buen invento

Notifications are excellent and very accurate when detecting water

1. The product description states "effortless installation" - placing the units is easy - but configuring the software installation is not. If you are at all phased by IT connectivity - try another system that is more easily installed. 2. This was delivered to the UK from the USA - so it came with a USA 2 pin plug.

I just bought them the hub with 4 sensors and an extra 3 without the hub. They are all connected I used Ethernet connection to wifi on second floor. Hub covers right to main floor and furnace room and main shutoff in basement. I cannot say how long the battery lasts as just purchased. My friend had one and he to,d me 3 years and still hasn't changed battery. No false alarms so far. I'm happy with product. Seems made of good quality.

This is a really good, easy to use system that work terrific. I have them in my home and cabin, both for water leak detection and they have saved me twice from a water leak doing major damage. Besides the leak detection I have a water temperature monitor on my hot tub and a water depth finder at my cabins fresh water tank. I have never had any issues till recently the hub stopped working and was replaced on warranty. Thanks again.
