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."
- 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. Itās 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"

"YoLinkās [sensors are] the only ones able to maintain a clear connection at such a vast distance. Theyāre an excellent fit if you need sensor coverage across a large property, or in a separate area such as a detached garage."
Best for Large Properties Water Sensor
āFrom the simple setup to the swift and reliable alerts, YoLinkās water leak sensors impressed.ā
Best Whole-House System
āThe 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.ā
āEasily the best range of any smart-home hub youāll encounter.ā
Top Pick Best Smart Security Systemes
āComprehensive set of door and window sensors at an affordable price.ā
ā[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 qualityā

Let customers speak for us
from 849 reviewsThe eco does not work on my main water valve due to a āstopā built into the original water valve. I am considering either modifying or replacing the valve before sending the YoLink back. The house and plumbing were all new in 2018 so I am surprised the YoLink did not work out.
I am also struggling to activate the hub via bluetooth since I do not have any open ethernet connections on my home internet system.
Couldnāt be happier as the installation came off very well and both the valve and controller work as expected.
The valve controller 2 with bulldog has worked very well. It was easy to install and has, so far, opened and closed my water valve on command.
This DYI unit is awesome, easy to install and works great. I had to use custom service to make sure I had the setting set correctly so the unit automatically turned off once the sensor sensed water. Customer service was beyond great. Very kind and knowledgeable. Great productā¦
This is my 9th water sensor, theyāre very easy to install. I bought this one to monitor the water line behind the refrigerator. I tested it with a little water after installation and it notified me immediately. I also get a discount on my home insurance for having leak detectors.
They are super easy to use, work great, and didn't break the bank! I spent less than $500 to monitor 20 refrigerators and freezers! By having the running data, our service man was able to quickly determine a problem with one of the coolers and get it fixed right away. He said he wishes all of his customers had these!
Works great
Simple device that works. Reliable connections, long battery life, and easy installation. I recommend YoLink to all my friends.
I'm always thrilled when something does exactly what it says it will do. Easy installation, easy set up (well, okay, I didn't realize the sensor thing would not show up as a separate device in the app even though it is a separate piece, and that kind of confused me for awhile), and I am very happy with the results. No clicker in the car. So long as I have my phone, I'm good.
We live in a gated community and we have a garage. Who wants to carry multiple remote controls in their cars for such things? And I don't like having a remote in my car anyway since it's just another thing for a thief to steal from the car. But I digress... our house happens to be right next to one of the community entrance gates, and we are close enough that we can open the gate with a remote from within the house. So we mounted the gate remote and a YoLink Finger to a cutting board and then placed the cutting board in a good place for signal to the gate. No need for a controller to know if the gate is open or not because the gate already automatically closes on its own. It's been great! I launch the app as I approach the gate, the Finger does its thing inside the house. This is all much easier than fumbling in my purse or the glove box for a remote.
I just installed one of these and it wasn't hard at all. The device to device pairing was also a breeze, it just took a little ove 10 minutes because I had 8 sensors to pair, ut great product so far. I hope they integrate the Matter protocol into it soon
Very impressed with the sensors and how the app works with them
Already have 3, bought 3 more - can be used in so many ways, start with your fridges and freezers to not only set the best temperatures but also get alerts if anything changes so you have time to react before it's too late. Great historical data too - used one to monitor the air temp outside dive during the eclipse! Easy to set-up and easier to monitor from anywhere.
Great little plug. Great range and remembers itās schedule.
Great fobs. Great range and great functionality.
