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 water sensors are exactly what I have been looking for and dreaming of!! I put them in areas of the house that I’ve had past issues with pipes leaking and in the basement around the furnace and water heater just incase something happens I will get an immediate alert rather than me finding the disaster days later. I even bought more of the sensors to put in other areas. Everything from the app works great and was relatively easy to bind. I even asked the company a question and they got back to me within a day. I have nothing but good to say about this product! I also tested the sensors by placing them on a wet paper towel and they instantly detected water and my phone elerted me!!

Works - does it's job. Support is excellent. Called for some help. They walked me through it. In hindsight it was me not reading all the directions. The system is not hard to set up; it was my error.

We have 20 YoLink temperature sensors. We put one under every sink, toilet, fridge, water heater, washer, dish washer, under the house, etc. The devices detect water quickly and accurately. They are also rugged, compact, and nice looking. Setup was incredibly easy. The app is great. We get phone notifications and emails (depending on my setup) as soon as a leak is detected. In fact, we had a slow leak behind the washing machine, which we discovered through the device.We purchased these leaker sensors because of their excellent ratings to protect our home. Once, before we had these devices, we were out for a few hours. The valve under a toilet cracked slightly and water started leaking. The carpet and padding were soaked. We dried and shampooed the carpet, but the carpet smelled bad for weeks, and we had to replace it.Customer service is excellent.We are very happy with the YoLink water leak sensors. They are essential for protecting our home from water leaks. We also have other YoLink devices and are happy with all of them.

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.

Works well. Setup was difficult and I had to call tech help for support. After learning how to do one puck the rest was easy. You will need to purchas another 5 pack to completely cover all appliances, sinks, W/D, sinks, and water heaters
