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 2079 reviewsWe installed brackets where the only wall space available to hang a water sensor type 2 was in view. I placed the brackets (and the sensor type 2 cords) along our baseboards, and it looks "finished" and reasonably attractive. The water sensor type 2 fit nicely in the bracket, helping to get the "finished" look.
I have installed 10 of these around the house and the crawl space. I have not had a leak yet, but every time I have tested each cord attached to a water leak sensor 2 before placing it, it gave me a warning each time. Also, I like how the Yolink app gives us a picture showing the remaining battery life. Also, for areas where you want the sensor 2 above any water (they are not waterproof), the brackets Yolink sells, and the cords look good along the floorboards.
Hub setup and works like it should. The QR code had trouble with controller and had to get it replaced received new controller and scanned QR code and downloaded internet took less then 10 seconds everything works like it should
When moving away from wifi sensors I was worried the setup would be hard. YoLink made it so easy! Sensors are connected in seconds and reporting over long distances, through walls and fast!
I wanted to automate a few things in my home...but I took the risk and bought 10.
I'm so glad I did. It has caused me to re-think the level of 'smartness' for my home. These things are great...only take a few seconds to add to my YoLink ecosystem!
Follow up to previous review, purchased original device to monitor pool water level, great device but had an issue with it a few weeks into it. Contacted customer service and after submitting a video showing issue a new device was received, device working as expected, kudos to customer support
Very slick and works as it should. I would like to see a few software changes.. such as programmable upper and lower limits for setpoints to eliminate tampering and excessive setpoint settings. Also possibly a lockable screen so no adjustments can be made without a password.
Been using it to detect possible washing machine leak and found the washer isn’t leaking but, the drain is slow and backs up and overflows. Great safety, troubleshooting, and monitoring device. I also use one to detect leaks in the basement, particularly after heavy rains and snowmelt. Easy to setup and very intuitive.
As with all the other devices from YoLink setup is a piece of cake, app settings are intuitive, accuracy is there, and it’s great for monitoring temperature and humidity trends. Currently using it to monitor crawl space humidity after some foundation repairs and crawl space incapsulation. Keep up the great work YoLink.
This 2-stage thermostat is packed with features. It works with heat pump as well gas furnace systems. And paired with the app, this tstat opens more possibilities and connection to the internet for remote access. The temperature sensor seems very sensitive, and I had to add 1.2 degrees when calibrated to a known temperature.
I installed two of these kits on my 1996 garage door openers, and they’ve been fantastic. Installation was straightforward, and they brought modern smart features to openers that I was ready to replace.
The range has been excellent—I can reliably operate the doors from about half a block away. Notifications are fast and dependable, so I always know when a door opens or closes. I also added a YoLink key fob in my car, which gives me a convenient physical button in addition to the app.
The YoLink app is clean, responsive, and easy to use. It’s a refreshing change from some other garage door apps that have become cluttered and less user-friendly over the years.
If you have an older garage door opener that’s still mechanically sound, this kit is a great way to modernize it instead of replacing the entire system. Highly recommended.
Very easy to install, great app system, with great features, easy to set up parameters.
It's nice to have all you questions answered anytime. It's also wonderful to understand how your well and pump are functioning.
The flex fob was part of our solution to making our 1996 garage door openers work again. Clipped it to my visor and everything works with a simple button press now. I really appreciated how there was a direct connection to the garage opener in addition to being able to work over the hub network.
I installed this on one of my pool gate. As soon as the gate opens I get a notice on my phone. “Gate is open”. It also lets you set a reminder that the gate is still open. You choose the time span. It’s really cool that you could add a siren to the gate also; if need . I didn’t do that yet. I will be adding more sensors to the other two gates. Easy to install. I highly recommend this sensor if you have pool gates or any other sensitive doors and gates you want monitored.
