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!

"Literally saved by thousands of dollars when it notified us of a sewer backup in our basement."

"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. It’s amazing"
- Marsiv
"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.
"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".

"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
“From the simple setup to the swift and reliable alerts, YoLink’s water leak sensors impressed.”

Best Whole-House System
“The 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.”

Top Pick Best Smart Security Systemes
“Comprehensive set of door and window sensors at an affordable price.”

“[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 quality”

Let customers speak for us
from 1681 reviewsReliable indication for 3 home levels. Like them, though do wish they had dual displays to show info from my YoLink outside temp/hygrometer.
I manage the water system for an HOA in Latin America, but I'm only there six months/year. Before I discovered Yolink two years ago, we never knew how much water we had in our tanks. Now with depth sensors and inline meters, we always know how much water we have on hand, and are alerted to any changes in normal patterns. We see problems as they develop and are able to attend to them before we have a crisis on our hands. The best part is that I can track the HOA system from my home in the U.S. We have not had one single disruption of service since we started using Yolink products two years ago. They are simple to install, intuitive to use, and the range is incredible. One of our sensors is 1500' from the nearest internet connection and works great.
If you have water storage tanks, these senosrs are great tolls
The fact that this product uses LoRa means the sensors always stay connect to the hub inside your house. And the 2nd thing that drew me is how really great the app on the iPhone was designed. It is VERY logical and has the setting that you would want to see in a product like this.
I have been a yolink user for about 4 yesrs. My major need was to monitor house while away for temp and water leaks. I have 5 sensors. The products are extremely reliable and the suport is top notch.
I actually used this as a simple open or closed sensor for a "low water pressure" switch setup for my well. Watering cattle all day so this gives me peace of mind that when I leave there is pressure in the plumbing. Cut the wires and wired them to a simple low pressure switch that’s normally closed. When pressure drops below set point on the pressure switch, this little sensor trips and I get a notification! Inexpensive and flawless! Can be configured to alarm either with an open or closed switch state.
Great product and even better service from YoLink.
An easy install anj just work very stable. Easy integration into Home Assistant
Installed hub and valve main shutoff kit. Had a leak from my water heater and the sensor shut off main water valve
System worked flawlessly. Have 8 of the 10 pack installed throughout my home. Highly recommend.
After purchasing the regular hub with four water leak sensors, they were working so well for me that I decided to purchase the local hub, since I prefer all my smart home tech to be ran locally. I was not sure whether it was worth it, given the $200 price. But since I’ve had it, I am glad that I purchased it.
For one thing, set up was really easy within the app. Second, it was very easy to migrate all my leak sensors from my old cloud dependent hub to this local one. Finally, after the migration, none of my leak sensors that I had already added to Home Assistant dropped off, so they did not need to be re-added, which is great.
All in all, I am very pleased with the entire ecosystem: the local hub, as well as the leak sensors... given how well they work, I will be looking forward to purchasing other devices from this company.
Works just like it’s supposed to. I have lots of YoLink stuff in my house and it just works!
These temperature monitoring devices are fantastic. Easy set up and customer service is second to none!
Thes pool thermometer works perfect an was so easy til install and get into my Home Assistant smart home system
I highly recommend this product. it works great and has great customer service.
I have leak detectors everywhere and also temperature monitors in several areas. Peace of mind is priceless.
As usual ,the device was easy to install and activate using the app.
Works well. A nice addition to my collection of Yolink/Yosmart gear.
Thanks again!
