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. It’s 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".
- 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"

"YoLink’s [sensors are] the only ones able to maintain a clear connection at such a vast distance. They’re 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
“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.”
“Easily the best range of any smart-home hub you’ll encounter.”
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”

First on failed over 3 years but for the money there is nothing as good or cost effective. Hoping this one lasts longer.
Excellent customer service…
D2D is limited without the App ( No Controlled Settings - Just on/off). APP doesnt communicate directly with HUB thru WIFI only. Forced to have Internet Access to use any automated Setting in the App. Relay need common contact for NO and NC so it is useful both ways. If YoLink would upgrade the App to communicate with the Hub without re-routing to the cloud they would have what no other market has. We need everything that Yolink has, but the 1st company that can do what Yolink can do without forcing us to have internet service or using the cloud will be the best on the market. NO CLOUD, JUST WIFI - APP AND HUB ONLY . with that said Yolink is almost there ( The Best) will be even better.
I got the YoLink Hub 3 two weeks ago and really like it. I replaced two basic hubs with two Hub 3s and the switchover was seamless. All my sensors were quickly picked up on the new hubs. I set both hubs up with wired eithernet and WiFi backup. I added cellular backup to one hub since that is the one closest to my leak sensors and shut off valve. Normally that would be all, and I would be a happy user. But I have been testing the system by disconnecting the wired Ethernet and activating the valve by WiFi. I have also pulled the main breaker which turned off both the wired and wireless connection and my YoLink power failure sensor sent me notification through the cellular connected Hub 3. One battery & cellular backups have greatly increased my confidence that I will be notified in case of any emergency.
This is a fantastic product. Works just as described. I tested the wifi and installed a temperature transmitter 1/4 mile from my hub and it works perfectly.
Hub & One Motion Sensor Smart Home Starter Kit
Now I can’t wait for YoLink to give an outdoor camera that tilts and pans!
Been using these temp gauges for a few years now. Since my freezers are in the garage, the sensors have helped save a lot of meat, by informing me of temp issues. Was able to get freezers hooked to generators a few times when needed. Also rearrange some of the meat to working fridges.
I used Enerlites digital timer switches before I found out about Yolink. I really wish I would have found Yolink products sooner. I'm in the process of converting all my timer switches to these Yolink switches. For help of install of switch , I use outlet spacers & Decora screwless wall plates for a cleaner look. Traditional wall plates don't really fit correctly with the larger Yolink switches.
I have six basement sumps with automatic pumps. Occasionally a pump would fail and carpet would get wet. Prior to this product, I was using water sensor 2 that I modified by taping wires to one of the sensors to detect water in the sump just above the level on the sump pump. It worked but was not 100% reliable. This product was just what I needed
Easy to install and work as expected.
Relatively easy to program. I had a challenge with 1 issue, but your phone service rep was quick and we got it done.
