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 2106 reviewsworks great Had issues with tying in 4 h20 sensors to close the h20 supply water valve and also turn-off the mini plug. Support team helped with this. If I get an h20 alert, the ys5003s shuts off main water valve and the mini plug which kills power to my induced blower on my h20 htr and shuts the water heater off.
I was very concerned that it would be difficult to set everything up. Turns out it was super easy. One smart valve, 13 sensors, and the hub. Everything works. I did have to ask AI to help me set up a weekly test of the valve, but everything else was pretty easy.
Only been a few days installed but everything is working well and meeting expectations. I was the test bunny, will be ordering more for our entire condo association.
Easy to set up. Works like it should. Takes the worry out of “Did I remember to close the garage door when I left?” And the YoLink finger makes it so I didn’t have to worry about hardwiring anything new. Very happy with the product.
Finding out when temps in freezer go up much more helpful than simply instantaneous temp
Love this entire system. Easy install and great, intuitive interface
Works exactly as advertised.
Great valve, does what it should. Manual knob for open and close could really use an upgrade though. It’s flimsy and not fast. You need to turn it many times to get it closed.
I already had the wall plug powered version for main water supply valve in my house. Then I needed to control two valves outside where I have no power. The battery powered version was just as easy to install and connect to the app as the other one I have. If you need this type of thing I highly recommend YoLink.
Easy to install. Sensors have amazing range. Every home should have this.
I have installed the leak sensors under each sink, toilet, hot water heater relief, dishwasher, and washing machine. I know in seconds if there is a problem and where. I also have two of the smart switches, which i use to turn lights on and off in rooms even when we are gone.
We have Eero whole home WiFi and connecting the Ethernet model hub was a snap. Leak detectors connected via the app easily.
I have to say, I had my doubts when I ordered this (with hub). Searching the internet for a sensor without a corresponding security system attachment was daunting. I now have a fully functional garage open sensor to alert me if I left it open, that also can be linked into my Amazon Alexa system so I get verbal alerts as well as phone alerts. If you read the instructions, the installation and pairing is trouble free. I can also add additional sensors later, which will come in handy with a toddler granddaughter who shouldn’t be opening doors to certain areas of the house. I highly recommend this system.
