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."
- 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"
- 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?

Simple, Quick DIY Installation

Most Products Two Year Warranty

Hassle-Free Returns, Free U.S. Shipping for Orders $50+

Let customers speak for us
from 1354 reviewsOur block of units has been plagued with water leaks for a few years now and this system will hopefully detect leaks before they become floods. We are on our third rebuild after leaks both from our own unit and those above. I showed the system to other owners and they decided we would all fit them to our units given the history and costs of repairs. Insurance may even reduce if we present our case. Highly recommended.

I have the YoLink controller 2 w/130 DB siren with both batteries and an AC plugin that converts to 12VDC power. I have multiple other YoLink products and due to sophistication of how they can be linked to the hub and each other or as stand alone remote systems up to a 1/4 mile, I have had to make calls to customer support to properly set things up. They have graciously been willing to help me work out my garage, carport, and trailer as separate controllable systems. They have always been patient and willing to guide me along to get the best use of their products!

This is the best tool I've put into my greenhouse operation. I bought 3 sensors downloaded the app and hooked up the hub to my router. I can check temps anytime of day, anywhere.
I love it.

I love my YoLink products. The lock and its features are great however, the lock is SO BIG that I had to remove my dead bolt to be able to install the handle lock. Now I have a hole in the door that the handle lock coveres about a half in of. What to do? May be sending it back.

For now, it is up and running without any problem non stop so it is perfect.
All capabilities are fonctional as expected.

YoLink Power Fail Alarm, 120VAC Power Monitoring & Power Loss Alert, Hub Required

Garage Door Sensor, YoLink Hub Required

Although, I have not had a leak yet, my upstairs neighbor did and his sensors went off and he was able to prevent a large leak !

Easy to instal and connect. Worked first time with no issues

This valve controller is something that we should have and maybe most homes should have. However I have tried installing it with the 3 of the valve shaft adapters now and none of them seem to work for my water line shut off. Apparently they are not made for my water line shut off.

The water leak detection kit is a great product. The ease of setup was awesome. All set and ready to go.

Have sensors in all 11 fridge/freezers at our restaurant. Great products
