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!

"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.
"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
"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"

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 1834 reviewsThese water leak sensors are easy to setup and a great value. They are small and have great battery life. I highly recommend these sensors as a low cost way to catch water leakage.
I had my (vibe coded) dashboard for ventilating my basement up and running in minutes.
Excellent, installed in less than 30 minutes once the weather warmed up.
Have been using several Yolink products for over the last year and have been very happy with the product and the customer service.
This is my second set of YoLink products for a vacation home. Products work flawlessly and very easy to set up on the app
Just like all of our other Yolink products, this floating thermometer works perfectly at a very reasonable price. Set up took 10 seconds: press button, scan QR code, give it a name. That’s it. I put it in the skimmer so that it’s not floating around. Had to move the pool one to a different skimmer as the first one I tried didn’t have a good connection to the hub. We now have two of them: one for pool, one for hot tub. Love the integration with Home Assistant: I can put the switch to turn on the hot tub next to the current temperature. Works really well. We are huge Yolink fans.
Water Sensor detected water under a sink and notified me. Was able to check it and fixed it not long after the Yolink detected it.
Plug excellent and easy
The cable is the same high-quality as everything else. And it allowed me to install the controller where it works best. The only two complaints: I had difficulty locating it on the website to purchase, and I wish the cable that comes with the system was quite a bit longer.
Great assurance to monitor my home. Very easy to set up.
Reliable long range devices. Application takes a little getting used to, but works well!
I've been using Bluetooth LE sensors from another vendor for years for monitoring, but have had endless problems with poor range and missing cloud notifications. I just switched to Yolink based on a coworker's recommendation, and this starter kit was fantastic! No range concerns with LoRa, and the tiny SpeakerHub lets me have spoken alerts in the kitchen without having to worry about a mobile app getting deauthenticated. I would recommend the Yolink kit to anyone!
I have tried many brads. No other company has such a complete product lineup or the range and ease of setup.
