Why people love our products
"Scan qr code, and bind. Can't make setup any. Easier!!! Many components to the ecosystem. Works hand in hand with sensors, for doors, temp. Humidity, motion, water leaks, etc. So versatile of ecosystem, reliability beyond any other! No specialized batteries in all units. They seem to have thought of everything!! Would give all products 6 stars if I could!

"I ordered the hub, key fog, motion detectors, moisture detectors and sirens.
Great products! Easy to install, the app is well thought out and flexible and the range is unbelievable. As an AV integrator I've used a LOT of different "smart" products.
These are probably the best I've ever had the pleasure of installing."
- Fred F.
"Literally saved by thousands of dollars when it notified us of a sewer backup in our basement."
- Donald M.
"These are my only smart home devices that out of all, always work. There have never been any issues. No connectivity issues, no update issues, no battery issues. If you use smart home devices, you know how annoying they can be. YoLink just works, all the time. Itโs amazing"
- Marsiv
"These devices are brilliant. They are (by far) the least expensive brand of home automation products, have a MUCH longer range than all others, and simply work perfect - all of the time.
- Rick Z.
"Saved my freezer multiple times in the last six months. I'm absolutely thrilled with this product".
- S. Reesx
"Yolink products are the best. I never thought I would buy into a Hub system but that is exactly what makes this product work so well. Device to device paring is what makes there family of devices work so well even without internet or wifi access. Very accurate with nice graphical data in the app to monitor trends"

Best for Large Properties Water Sensor
โFrom the simple setup to the swift and reliable alerts, YoLinkโs water leak sensors impressed.โ

Best Whole-House System
โThe system is Bluetooth-compatible with iOS and Android, syncs with IFTTT, and works with smart home arrays like Amazon Alexa, Apple Homekit, and Google Assistant.โ

Top Pick Best Smart Security Systemes
โComprehensive set of door and window sensors at an affordable price.โ

โ[YoLink] utilizes a low radio frequency protocol (LoRa) to communicate. LoRa signals can penetrate greater distances than WiFi, and this system reduces the associated workload of routers. Every sensor I tested was of good qualityโ

Let customers speak for us
from 1891 reviewsThe Yolink water detection devices plus hub arrived promptly after my order was placed. The installation, even for a stone-age technician like me, went smoothly and easily, thanks to the great help and support of the Yolink telephone support team. I am very happy, and at peace of mind, with my yolink water detection system set up throughout my house.
I recently installed this unit in my home and it is working great. It is able to turn the valve and shut off the water within a few seconds of the leak sensors detecting moisture. I had to fit it in a tight space between my water heater and garage wall, so I had to mount the EVO Valve Operator upside down to make it fit, but it seems to still work fine upside down. It was a challenge to reach in and tighten the hose clamps, but I got it eventually. Definitely make sure you measure your space before buying, and verify that it will fit in both the open and closed position. The X3 controller gave me no issues and just worked immediately.
These work really well like all YoLink products in my experience. These are especially useful in Home Assistant integrations. Small and unobtrusive and mount on the ceiling itโs a magnetic disc included.
The sensor reaches out to my driveway which is several hundred feet long. Mounting braket was simple to screw into a pine tree.
Having YoLing in place avoids high contractor bills for undetected leaks.
Motion Sensor 3-Pack, YoLink Hub Required!
Iโm very happy with this motion sensor. It was extremely easy to set up, especially once paired with the YoLink Hub, and itโs been working reliably and consistently ever since. The detection range is great, the alerts come through quickly, and the overall performance has exceeded my expectations. A solid choice if you want a dependable indoor motion sensor for your smart home.
This is a life changer and helpful in many ways as I am disabled. I know when itโs open or closed , can open it for deliveries or for friends and family etc. I never get down stairs and there was a flood . Now with my leak sensor no more fretting no more imposing on family and friends to check down stairs etc. MORE INDEPENDENCE!๐
Works great, good value, no issues !!!
Now they just need to come out with an outdoor motion detector floodlamp camera setup !!!
Temperature & Humidity Sensor, Hub Required!
I have been using a YoLink hub and thermometer to monitor my fridge in Toronto and had such a good experience that I bought one for my winter home in Europe. After hours of research I could not find a similar product there. I was delighted to find out that the hub and thermometer would suit my needs. I had some difficulties setting it up but the customer service I received was unprecedented!!! It is now working like a charm.
Excellent lock , very satisfied thus far. Flexible programming, great automated routines. Easy install!
