YoLink Water Leak Sensor 3-Pack, LoRa Up to 1/4 Mile Open-Air Range Smart Water Leak & Flood Detector, SMS/Text, Email & Push Notifications, w/Alexa, IFTTT, Home Assistant - YoLink Hub Required

After having constant issues with the Guardian water leak detection system, I was on the hunt for a more reliable and user-friendly alternative, and I’m so glad I found the YoLink Smart Water Valve Controller! The installation was a breeze, taking me around 30 minutes to set up the controller, and a bit more time to configure and place 16 leak detectors around the house. The process was straightforward and easy, even without the need for a plumber – it's truly DIY-friendly. Now, comparing this to the Guardian system is like night and day. The Guardian was a headache, constantly failing, poorly designed, and honestly, it cost a fortune. Each Guardian controller was $50, and they kept failing on me. With YoLink, I’ve found a much more reliable and cost-effective solution that works exactly as advertised. Setting up the YoLink system was incredibly intuitive. The app is user-friendly, and I was able to easily configure the settings, including the wireless range, which works flawlessly. Even with multiple walls between devices, the system remained reliable with no drop in connection. It’s great to have peace of mind knowing that everything is connected, and I can manage it all from my phone. One tricky part for me was figuring out how to automatically trigger the water valve to close when a leak is detected, but I solved that by using the Automation tab in the app. Once I set up the events, the system worked perfectly. Thankfully, I didn’t need to watch the instructional videos since I’m already familiar with these kinds of systems. I’m beyond impressed with how well this system works. It’s easy to update and configure, and I now have total peace of mind knowing my home is protected against water leaks. If you’re tired of dealing with a poorly designed, expensive system like I was, I highly recommend the YoLink Smart Water Valve Controller! It’s been a total game changer for me. **A++++ – Highly Recommended!**

TLDR: These are *AWESOME*!!!!!!!! I have to admit, I was *really* skeptical of the "YoLink" family of products when I bought them. It sounds kind of hoaky and well, I didn't think it would work all that well. BOY, I WAS WRONG! I bought a YoLink Hub with leak sensors and bought this 3-pack to protect extra areas of my home. About a week after installation, they went off when my water heater relief valve let go and the water got shut off immediately so that the flood was very limited in scope. These devices are awesome so far, and I am so glad I have bought them. I also bought sensors for my refrigerators and a water shutoff valve motor that automatically shuts the water off to my house if a leak is detected. I can see the status of my home from anywhere that I have cell signal! Installation: Couldn't be easier. Get the app from the app store, click on the "scan" button and scan a QR code on the back of the device. It gets added to your YoLink Home, and after you power it on, you get instant feedback as to the health of the device, the health of the connection, and the status (alarmed or normal). 10 seconds per device to install. You can name each one, organize them into rooms, and many other options. Function: I tested the leak sensors by licking my fingers and bridging the contacts with my wet finger. Each one I have bought has alarmed on all of the sensors on the device. There are two sensors on the bottom and one on the top (cleverly in a little "cup") that would hold water if it were spraying everywhere. App: The app is pretty decent. I get a dashboard that lets me see my whole home at a glance. There are a few confusing parts, like Scenes, and "Automation" which are not immediately obvious. But they have a few videos that help and their customer service was pretty responsive. Range: I have a sensor in the basement freezer and one in my kitchen refrigerator. While they aren't horribly far from the hub, they have full strength signals despite being in cold temperatures and inside the refrigerator boxes. Battery Life: I cannot comment yet, but they are not replaceable and are supposed to last 5 years. I hope that's true. But even if they last a couple years, the disaster they save you might be worth it. Installed locations: Under each bathroom sink, Under kitchen sink, Under each toilet tank, near my washer and dryer, behind my refrigerator (icemaker has leaked before), Near my boiler, near my water heater, near the A/C condensate pump. Overall, I couldn't be happier with my YoLink system. This was well worth the money, especially since it already saved me from one bad flood.

I bought these after we had a leak on the line going to the ice maker on our refrigerator. We had quite a bit of damage, and I told myself "Never again". They are easy to set up and send an alert to my phone when they sense a leak. I highly recommend them.

These are great! I've been using them for years now. I added a hub and sensors to my elderly parents home as well. They think I go over the top with tech but just a few weeks ago I got a phone call from them. While they were at my dads cancer treatment center, they were getting an alert from one of their leak sensors in their garage. I drove over to check for them and sure enough, the water heater had just barely begun to leak! The leak was so small in fact, I had to pick up the sensor to see the tiny bit of water. I had the sensor sitting in the pan they typically put the water heater in. They were pretty happy I had installed the sensors and now really see how items like this can save you from a flood or worse. And when the new water heater was installed, the sensor wouldn't fit in the new/smaller pan they used. YoLink also has a rope water sensor which is PERFECT for this. I ordered two. They have a length of rope-like wire you can drape around things. You can even add extra lengths of the wire to extend it if needed. I'll also say that over the years YoLink support has been awesome and it looks like the company just keeps growing, releasing better and better products as they listen to their customers to keep producing useful items. I also have the water shutoff valve which I haven't installed yet but will be, along with some temperature sensors (great for hurricane areas/power outages when you don't know how long the refrigerator may have been turned off for, to know if your food has spoiled), the siren, speakerhub, garage door sensor, magnet door/window sensors.. I have the floating water temp sensor in their in-ground pool so they dont have to bend all the way down to pull up an old school thermometer (hard to read) from a string. With the YoLink temp sensor, they just look at their phone and can get alerts for low/high temps so they can turn their solar heat on or off. I really can't say enough good things about their products. Great job YoLink!

These sensors have worked well and given us peace of mind when leaving our house for extended amounts of time.

These work very well. Giveing 4 stars only because the valve control right now does not completely turn off the water rendering the solution useless. Going to try and adjust it. Love the concept, seems to be of good quality, but right now valve does not work well. The sensors are great and easy to configure.

I was a little skeptical at first, but this item turned out to be exactly what I was looking for. It arrived on time and in good condition. The quality is solid, and it works just as described. Setup was straightforward, and I’ve had no issues so far. Definitely worth the price. I would recommend this to anyone considering it!

The YoLink Water Leak Sensor 3-Pack add-on pack has been an absolute game-changer for protecting my home. I already had a YoLink hub set up, and adding these sensors was seamless. Within minutes, I had all three sensors connected and strategically placed around my home—under the kitchen sink, near the water heater, and next to the washing machine. The range is fantastic, even sensors far from the hub still connects flawlessly. The real-time alerts are super reliable and give me peace of mind, especially when I'm not home. If you already have the YoLink system, these sensors are a no-brainer for expanding your home's water leak detection. They’re simple, effective, and give you one less thing to stress about.
