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?

Simple, Quick DIY Installation

Most Products Two Year Warranty

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

Lifetime Support, U.S. Phone Support Available
Let customers speak for us
from 1586 reviewsBought more sensors for every leak point in the house (16). I feel very secured and safe from flooding.

My issue was handled quickly and efficiently. Exactly what I want when I chat with support.

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

Product works as advertised.

Well built, functions flawlessly, as with all YoLink products excellent WiFi range

Did not disappoint. Would definitely buy again. Amazing range.

YoLink has proven to be a great company with reliable product and great back-up service - I highly recommended their products.

These work well. I can’t get WiFi to the detached garage but these YoLink sensor get plenty of signal and work flawlessly

I purchased the hub, relay and 2 smart plugs to connect an emergency exhaust system my new R32 HVAC system. It notifies me by email if the exhaust is activated by the furnace alarm, indicating a possible leak in the system. I will be connecting more YoLink products to the hub soon…it’s so simple to connect, set-up and use. Thanks

Both work great. I'm impressed with how they perform.

We use these YoLink Monitors to track inside temps on the Refrigerated Containers we buy and sell. Great Product ! Mike Doss USA-Containers, LLC

Did exactly what they said it would do. Very long range and reliable.

I started using YoLink this year and have been alerted twice to water issues in my home. The Water Link Sensor linked up with other YoLink devices has detected leaks, turned off water and notified me of the leak and location. So, I bought more and now have all sinks, toilets and common areas under the watchful ’eyes’ of YoLink.

This YoLink float switch is the second product I purchased. Simple and reliable with great customer support to go with it. I had a specific application I wanted to tackle and YoLink gave me great advice on which product would best fit the application. Product was welll documented in the manual and installl was a breeze. A big deciding factor for me in selecting YoLink was temp range (I have sensor installed in a pipe outside my house exposed to low temps during winter), battery life, and radio range. They were the best I could find. I’m super happy with my purchase decision!
