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

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!

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!**

I bought a hub & a few of these for our new house after we had a leak. It is very sensitive & has had false alarms because some drips of water from the laundry gets on it, but I would rather that happen then it miss a leak. It has prevented damage & given us peace of mind. The batteries have lasted for years & are still full of charge. They could not be any easier to set up in the app, SO easy!

I found a small leak under the master bathroom sink, it was leaking for days and made it into the sensor, if I did not catch this quickly, the wood below would’ve been rotten.This was a brand new house, with a brand new high-end faucet.The root cause was an indentation in the O-ring from the factory, I was able to source a new O-ring from Home Depot. Warranty with the faucet manufacturer would’ve covered it, but it would’ve taken forever.

Paid for themselves a month after installing. My washer hose started dripping, and the sensor alerted me to a leak before half a cup of water was on the floor. No telling how long it would have leaked before I noticed otherwise.

Works as described. Good range. Price is good and will save you a ton by detecting and alerting leaks. It works with Google home, and I can see a leak condition detected in Google Home - however I can not find a way for Google Home to alert me on leak detection. I do get an email and an alert from the YoLink app when a leak is detected

I’ve tried a number of different hubs and smart home devices and Yolink wins hands down.With over 72 Yolink devices ranging from switches to hubs to fobs to smart plugs and more. Many of which have been in service for 2+ years. Yolink devices are extremely easy to deploy and easily integrate into Google home and Home Assistant – but I use the Yolink app 95% of the time. Battery life is unbelievable – changed my first battery yesterday. Most of the devices are still showing 50%. Even more impressive is the range – even with the device inside a metal postal box and hundreds of feet from the house. Also like the fact you can add fault tolerance by adding a second hub by simply scanning in the barcode on the device. Customer tech support is also top notch.
