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 1996 reviewsCould not figure out why the ice maker stopped working,, freeze -3 F, ice maker need (-1, 0, +1 ) to work reliable, to some tweaking but found a freezer setting and it work in the above range and now it works all the time
Every new home should have one of these automatically installed on the main water valve and older homes should definitely have the homeowner install one. It literally takes one minute to install with ENDLESS peace of mind that a water leak will NEVER damage your home. This product is worth its weight in gold. Thank you Yolink.
To install valve itself it’s better to get a plumber.
Hub and sensors installation is not complicated
YoLink Customer service is excellent
I am slowly building out my smart home and YoLink has been an integral part of the process. I recently purchased their garage door sensor and controller kit and it's been amazing. Not only do I have control of my garage from anywhere, I also know if it's open or closed. This has saved me a couple of times when something interrupted the door while closing. Instead of leaving my garage open all day, I got a prompt notification and was able to check and close the door remotely.
Very happy with the product. I use this with Home Assistant via the YoLink hub
My second valve robot purchase was a gift for my process wngineer son to install in his new house. He works with refinery and transmission control systems and was impressed with the ease of install, performance of the actuator, and the featuresbof the software. He especially likes the fact that the X3 is battery powered.
I purchased a Yo-link Water Depth Sensor that was not working correctly and I contacted Yo-link customer service, troubleshot the device with them and they had a replacement to me in about a week. I appreciate the fact that they stand by their product and are quick to correct any problems. I have many Yo-link devices and they work as advertised!
Had a link under a sink. Already had the garage door sensor and hub. Gat a leak sensor for each sink in the house. Tested each with a little water. Heard the alarm, saw it on the app, and got an email. I don't worry about hidden leaks creating mold in my house.
My hub is in the basement and the pool thermometer is outside in the inground pool about 100' away with lots of obstacles in between and the signal is strong. Accuracy and resolution are very good. Awesome product.
Works fabulous out of the box
Motion Sensor 3-Pack, YoLink Hub Required!
The siren alarm works great, it gives you an audible alarm to know there is a water leak as long as the sensors work properly!
Very happy with everythign include the support and service, thanks - look forward to working with you going forward.
