YoLink Water Leak Sensor 4 105 dB Alarm Kit: 4-Pack + Hub

I've been using YoLink Water Leak sensors since 22 and now have 14 of them, including the 6 siren-featured ones in this product. While I have never had a water leak (thank goodness) the sensors do work. I test them periodically and they always alert both my phone and email when they detect a leak. Also, when getting too much water near them while mopping the floor, they also go off. So they work. Also, the app is easy and intuitive to use. Customer service is also excellent. I tried to move 8 sensors from an old hub to the new hub and 3 of them wouldn't bind to the new hub. A quick email with customer care, and they reset the sensors and I was able to bind them. Customer care got back within a matter of minutes and the problem was resolved. The sensors are small enough to place where you need them. I have them under every sink in the house, under the fridge, under the washing machine, the dishwasher, the toilets, and next to the water heater in the garage. Their battery lasts years - some of them are 4 years old and their battery strength is still 75% or better. The batteries are easy to replace when needed. The siren sensors are ear piercing when they go off, so you will definitely notice when one of them detects a leak. They are very loud. Overall, after looking at a bunch of other water leak sensor systems, I found the YoLink system is a great value for the money, and it gives me peace of mind knowing I won't have an undetected leak.

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.

This product is awesome it saved my house from floods several times alerting me through text and email sent down someone to fix the problem right away before I had a tremendous overflow of sewer water in my basement this product is easy to install easy to maintain and it does the job perfectly also I had a problem connecting to internet I called customer service they picked up the phone right away and they were excellent to help me fix the problem right away I would recommend this to anybody who needs a good product and good customer service

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.

The YoLink water sensors have been great and are of good quality. Out of the box they were very easy to set up, have a strong connection, and alert me quickly if water is detected. I use several around my home and they give me peace of mind. Very reliable and definitely worth having.

Awesome sensors that are easy to set up and place around areas that I would want to know if a leak started. The app is simple, yet effective at monitoring each device and alerts me when a leak has occurred. Would recommend this to anyone looking for a simple, cost effective way to monitor their home for water damage.

I had them installed for a just a few weeks and they saved me. Got an alert for under our kitchen sink and was able to avoid a huge mess. Works great. Super simple to set up.

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.

Great product to protect your house from leaks , works perfect over wifi, send you notifications, email, sms when detected a leak. Has sensors from top and bottom. Also keeps beeping when a leak is detected, great system

Great!

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.
