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”

Why is YoLink the Smart Choice?

Let customers speak for us
from 1603 reviewsEasy setup, reliable operation, and a great value as well. Sold all around device, will need to pick up additional units in the future as we expand our system.

Great product! Easy to set up and gives me so much peace of mind if something were to leak.

For stuff like this, what matters most to me is that it just...works. And it does! I have the sensor in my chest freezer and I used the hub on wifi only because we have a router with no extra ports unfortunately. It's working great and I have a lot more peace of mind now. Probably will buy a second sensor for the fridge.

I have not had time to install it yet but this is my second switch.
I live in a real remote area and like the fact I can turn on my outside porch light before I get home.
My second switch will be for above my sink so I can operate it remotely or use the timer option.

Door Sensor 2-Pack & Hub Starter Kit

I use these detectors under each toilet, each sink, and each refrigerator. In five years it has saved me from water damage on three occasions.

We looked for an inexpensive and accurate way to include school bells (e.g. for recess and lunch), and to provide other emergency messages to each classroom in our small private school. The hub was a critical piece in this application, along with the ability to play back personalized audio files (like an old school bell).
In addition, we added aYolink Outdoor Alarm Controller connected to LED strobes and Yolink Mini On/Off Fobs for a silent alarm in each class . Each teacher has a fob we use as a panic button, that we've set to turn on strobes in every class should there be a threat in or near the building giving our teachers and students an early warning system.

I've had several water leak detectors and also some other 2.5G items that took a lot of time to pair and get working. The YoLink Hub got my 5 leak detectors running in less than 10 mins! I'd definitely recommend if you're looking for an effortless install.

Have used Yo-link door sensors for years. They work perfectly and the batteries are still original!
Great product and will not disappoint.

Delivered on time, water sensor works fine.

Works well relatively easy to install. Since building in 1998 I have had three water leak events, Yolink water leak detector saved a Attic hvac air handler possible over flow this year.

YoLink is my go-to for whole house automation.
I currently use Home Assistant (HA) to control irrigation, wastewater, indoor and outdoor lighting, and solar. YoLink products seamlessly integrate with HA and make things easier for me than other vendors.
