Why people love our products
"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."

"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"
- Richard
"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. It’s amazing"

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 1647 reviewsThe set up was very easy however getting the sensors to react was a little tricky. I had to contact customer support to get the right instructions. They did send me step by step instructions so it all went well. Hopefully, the system will never be used but I have tested it and the sensors to make sure that should a leak occur, it will be handled correctly and automatically, just as I want it to. Good thing I did do a test because there was an item near the controller that was impeding the arm closing all the way. Had I not, I would have had an issue. Just a word of advice. Once you set it all up, test your sensors to make sure that the power pack reacts the way you need it to. The snesors are very sensitive so that is a big plus. A wet napkin will set them off.Highly recommend this system.
It’s exactly what I needed! I have the speaker set to say a warning phrase if someone enters our horse barn between certain hours in the night and early morning.
Works great. Well worth the price.
I am using my siren with the six outdoor motion sensors that I placed around my house. The siren works great. The setup was easy.
I purchased the YoLink Door Sensor Starter Kit with a YoLink Hub. I love this initial set. I use it on a condo that I rent. I can easily monitor when the renters arrive and if they have the door open and the AC turned on. Great money saver. Works great and all the time.
GREAT PRODUCT!!!
I ordered four more relays.
Ordered for Amazon, they were a $1.00 less on each and shipping was free.
When I need addition modules, will YoLink have free shipping.
YoLink Hub with Two Temperature & Humidity Sensors, Smart Home Starter Kit
Got it all set up in minutes. Tested great. Easy to use. Huge leak detection footprint with the cord. Integrates with Home Assistant. Long battery life, long distance wireless. Didn't like having to set up a whole new hub for my smart home, but that's a minor inconvenience.
I now own 8 temp/humidity units and 2 hubs. This system is easy to setup and work great.
I went on a walk. I was at least 1/4 mile away and tested my plug on a light it worked I was amazed.. real game changing tech.. Thank you Yolink for a great product! PS I also really like how you included a charging port for the fob!
The product works without any issues. Instructions were good. Door notifications , open & closed are punctual. Thanks great value.i also have room & refrigerator/ freezer modules on system. Power went down and I was notified of temperature problem . That paid for the equipment. Thanks so much , I am very happy I bought it .
Works like a dream perfect solution for what I need
So our farm building are spread out a bit. Greenhouse, special raking systems inside greenhouse, storage rooms, open fields, pump house at the far end. And ai always know what the temperatures are. Sometimes it causes me to get up, put on a robe and head outside at midnight. And that is a good thing. Oh, and the original set of sensors has been up a couple of years.
