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

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.

Incredibly easy to set up. The system communicates well and is very rapid to pickup leaks. Great item to have

The sensors work great! I have 2 water leak sensors (by the refrigerator and water heater) and 2 temperature sensors in the house (1 is in the garage). The [hone app is easy to install and easy to use. The sensors are a breeze to install as well, (using the QR code for installation is the fastest). I have mine set for phone notification as well as email.

If you are running the YoLink system, buying more sensors is not a maybe it is a must. I picked up this 3 pack to cover the rest of the house and it was a no brainer. Setup took minutes, they synced right up, and now every risk area is covered. Under sinks, water heater, laundry, you name it. These things catch leaks fast and alert you within seconds through the app. Pair that with the automatic shut off and you are basically shutting down problems before they turn into expensive lessons. The range is legit too. No signal issues, no drop offs, just solid performance. At this point, if water gets loose in my house, it is going to have a bad day not me. Bottom line, if you already have the system, do not cut corners. Get the sensors and cover everything.

Fantastic devices and easy to test. Work perfectly and simple to setup, especially if you already have Yolink devices. All Yolink devices I have been great to use so far.

Very easy to add to existing system. Yolink devices are fantastic and app is easy to use.

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.

These little detectors work great are small and affordable. I have purchased 15 and have them all over my house even inside walls where critical valves are located

I didn't know what to expect, but I heard this product was good. It arrived quickly, was REALLY easy to install and connect with the mobile app. Works perfectly. I have 5 installed in my condo and another 4 installed in my country cottage. You can view their functions by house, location, etc. Highly recommended. Try to wait for a sale, since they are kind of pricey, but they are certainly good.

Works well once reset to Europe wifi but it would not connect with their European/UK hub without a fair amount of resetting and liaison with tech support. I was expecting this so was not a problem for me.

Works very well and detects water, notifications are excellent

This is the eu version that operates on a different frequency to the us hubs. It does not connect to my hub

I have a lot of Yolink items and they work perfectly. Great to monitor water leaks for my water heater, washing machine, water pressure tank and even inside my sump pit. I installed it inside (within an abs cap) right over where the pump is located. So, if it detects water, so I have still time to fix it before any damages.
