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".

"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"

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 1108 reviewsGreat product..gives accurate feedback all the time
Very easy to use and work great thank you
This purchase was to protect a second home. Our primary home was already protected with leak sensors and it saved us from major damage when one of the detectors sensed water early… before it became a big issue. They are easy to set up and the YoLink app helps monitor everything.
Temperature & Humidity Sensor 3-Pack, Hub Required!
A week after purchasing this device, my phone started going crazy with alerts that a leak was detected under my Kitchen sink.I was able to turn of the supply lines before any damage occured. I found the leak and repaired it. Thank you YoLink
Everything works great as usually. Great product
I was told of the YoLink sensor by a friend, after a major bathroom leak. I am glad that he told me about YoLink an I now have multiple sensors in the house and will end up adding more of them, in the house at various locations.
Nice simple app too
Works great. I use it with my deep freezer.
product works fine for my application
X3 Outdoor Temperature & Humidity Sensor
Installed 18 water sensors acrossthe house, a centralized siren, hub and water valve. Have eliminated 98% of the possibilities of a water leak. In the future, will add a Yolink relay to the power going to the well pump to completely protect my house.
We have a freezer in basement loaded with meat. As it is in the basement it does not get a lot of notice. We have always feared that an unexpected / unnoticed power outage or the freezer just breaking occurring and all the meat going bad. Now with this sensor we are always notified of the temperature in the freezer and giving us time to move meat in case of an emergency.
Weatherproof Temperature and Humidity Sensor, Hub Required!
