Customer Reviews
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!
- John B.
"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. It’s 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
“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 1948 reviewsAndroid version works well with 4 water sensors and 1 temperature sensor. When traveling, I sometimes log in to see if all 5 are functioning...they always are.
…It takes some thoughtful review of the app (iOS) to configure the switches to your preferences.
I ordered the wrong model. Clair at YoLink Shipping/Customer Service did an excellent job of getting the correct model sent to me. I’ve been very happy with YoLink products and customer service. Highly recommend them.
Great concept for an ever-expanding YoLink ecosystem! Extremely reliable and tuning in a few alarm strategies is always a plus. Will eventually buy more for garage and shed spaces.
I am a controls engineer, and am delighted at the simplicity, reliability and accuracy of the Yo Link products. Great customer service as well
I bought the YoLink hub (and water shut off valve and water leak sensors) primarily for peace of mind. I’ve seen what happens when a faucet connection fails and runs unnoticed for hours. With the YoLink system the water damage will be greatly reduced. It was easy to install and setup.
Installed easily with male compressions. Valve works very smoothly and quietly. Combined with the battery backup, speaker hub and water sensors, valve will shut off in the event of a leak, it will even work in a power outage by using the LoRa network to shut off the water. Very easy to install and to use.
These are great switches for home automation. I’m replacing most of the switches in my house with these.
Valve Controller 2 & EVO Valve Operator
I wanted this plug/switch to control when my hot water recirculating pump runs. It was very easy to setup and is working as expected - perfectly.
ME GUSTO LA RAPIDES DE LA ENTREGA
Easy to apply, accurate and super reliable. Fantastic fior on site and remote monitoring of temperature and humidity including graphical display over long term periods
