Water Leak Sensor 4, 105 dB Alarm, 3-Pack, YS7906

Set up was super simple and the sensors work great. The Yolink notified me of a water leak in my guest house (by text) when the water heater failed and we were able to shut off the water main before any damage was done. Hub is in the main house, so I am impressed with the range of these sensors. Excellent value for the peace of mind these little devices provide. Great product!

Within the first week, I heard beeping coming from under the kitchen sink, and low and behold, we had a small leak under our sink! It really gave me peace of mind that this will keep us from suffering a costly home repair, or major damage when we might be away from the house. I would recommend! Setup was super easy and took very little time. The beeping wasn't overly loud, but loud enough to hear from several rooms away, and the app will also send an alert.

Easy to setup, no issues pairing with the valve and the sensors work as advertised. As long as the batteries last I'm happy

After recently dealing with a water leak, I installed the YoLink Water Leak Starter Kit (Hub + 4 Leak Sensors) in four different locations around my home. The setup was quick and straightforward, and testing each sensor was simple. The system has been working reliably and gives me peace of mind knowing I'll be alerted if another leak occurs. I'm so satisfied with it that I'm planning to add another sensor to monitor our water tank.

These leak detectors appear to be well-thought-out and I have tested them several times and they all worked perfectly with the required hub. YoLink just came out with an audible hub which announces where the leak is. You can also set it up to provide you with text alerts as well. This set up cannot be beat and their CUSTOMER SERVICE took care of any questions I had.

I’ve had the YoLink smart water leak detection system installed across my property for a few months now, and it is hands-down one of the best smart home investments I have ever made. The Product Performance: Unbelievable Range: Unlike traditional Wi-Fi or Zigbee sensors that struggle to maintain a connection through concrete walls or long distances, YoLink uses LoRa (Long Range) technology. I have sensors placed in distant corners—basement floor, under the kitchen sink, and out in the garage—and they instantly report back to the hub without a single dropped connection. Rock-Solid Reliability: The response time is practically instant. During testing (and an actual minor sink drip), I received phone notifications, emails, and loud alerts on the hub seconds after water touched the contacts. Fail-Safe Operation: What really sold me is device-to-device pairing (YoLink Control). You can pair these sensors directly to a YoLink automated shut-off valve. That means even if your Wi-Fi drops or the power goes out, the sensor will still tell the main valve to shut off the water instantly. Battery Life: They run on standard AAA batteries and consume almost no power—expecting 3 to 5 years of battery life is a massive upgrade over devices you have to recharge constantly. Customer Service: I had a quick technical question during setup regarding automated alerts. Reaching out to YoLink’s support team was a surprisingly pleasant experience. I was able to connect with a knowledgeable representative who answered my question right away without giving me generic scripted answers. It’s rare to find a company that backs up a high-quality product with genuinely helpful, responsive customer service. Verdict: If you want to protect your home from devastating water damage, stop looking at basic Wi-Fi sensors and get the YoLink system. It offers commercial-grade reliability at a consumer price tag. 10/10 recommendation.

Easy set up, works as intended, as others have stated the audible alarm isn't really all that audible, however if you're hooked up with your phone, you'll get a warning there, I haven't connected to my Home assistant. I wrote with a magic marker the location of each sensor with the same description as the hub set up (Kitchen-Sink) , programmed them all at once at my kitchen table then placed them in their location, if they ever get moved, battery replaced, etc., I will know which one goes where.

Very easy to set up. I tested one and the alarm sounded and I received a notification on my phone. It worked exactly as it should. After a few months I received an alert that one of the sensors was "offline." I spent quite a bit of time trying to figure out the issue but after about 10+ hours the issue resolved by itself and the sensor was back online. It certainly helps with peace of mind.

Buen invento

J’avais déjà un ancien détecteur de fuite d’eau acheté après avoir réparé une toilette moi-même, mais je le trouvais assez coûteux pour en installer plusieurs dans la maison. Après avoir comparé les options, j’ai choisi les YoLink notamment parce que je voulais recevoir une alerte même lorsque je ne suis pas à la maison. J’ai commencé avec trois capteurs et j’en ai racheté trois autres quelques jours plus tard. Ils sont maintenant installés sous mes toilettes, sous le lave-vaisselle, près de la douche et à différents endroits où il y a un risque de fuite. Après plus d’un an, je n’ai eu aucune fausse alerte et j’ai eu une vraie détection d’eau dans une salle de bain. Le capteur a réagi rapidement et j’ai immédiatement reçu l’alerte sur ma montre. C’est exactement la raison pour laquelle je voulais ce système. Une fois le hub et l’application installés, ajouter un nouveau capteur est extrêmement simple : je scanne le nouvel appareil et il rejoint le système pratiquement tout seul. Je n’ai encore eu besoin de changer aucune pile. La seule chose à considérer est la zone que l’on veut surveiller. Ces petits capteurs détectent l’eau seulement là où ils sont déposés. Pour une grande zone où l’eau pourrait apparaître à différents endroits, YoLink offre aussi un modèle avec câble de détection que je trouve encore mieux adapté, même s’il coûte plus cher. Pour les endroits où une détection ponctuelle suffit, par contre, ceux-ci font très bien leur travail. Six installés chez moi et, jusqu’à maintenant, ils ont été parfaitement fiables.

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.

I don’t usually think much about water leaks, until one nearly turned into a very expensive problem. Installing the YoLink Water Leak Sensor ended up being one of those small decisions that quietly pays for itself in a big way. I had it set up two years ago, mainly as a precaution. Last summer, we traveled abroad on vacation, so there was no one at home. I had left the main water supply on to keep the lawn irrigation running. Mid vacation, a leak started, at the worst possible time! What made the difference was the instant alert. I received a notification on my phone that water had been detected. Instead of finding out 10 days after, I was able to act immediately. I called a friend who had a spare key, asked him to check the house, and he quickly shut off the main water supply. That one alert likely prevented what could have been thousands of dollars in damaged floors, walls, and everything in between. It turned a potential disaster into a minor inconvenience. What I appreciate most is the peace of mind it provides, especially when you’re not home. It’s not something you think about daily, but in situations like this, it proves its value instantly. Looking back, it’s hard not to see it as an essential part of a home setup. It’s a simple device, but one that can make a very real difference when it matters most.

Great!
