Features
- THAT WAS EASY! Installs in moments: scan the sensor's QR code, give it a name, peel off the pre-applied 3M brand mounting tape protective plastic, press the sensor and magnet to the door and frame, and you have added security to your home or business!
- WHY PAY A MONTHLY FEE, when you can secure it for free? Self-monitor and save when you take advantage of our many ways to be notified of alarms and off-normal events in and around your home or business. See "Know Now!" for more information!
- MORE THAN JUST A DOOR ALARM! Track activity in your home or business. Be alerted to wandering children and elderly loved-ones. Use the sensors to protect liquor & medicine cabinets, gun safes, storage lockers & boxes. Place a sensor on your fridge/freezer door or lid and know if it was left open, to prevent food loss. Many more applications than just security!
- DOOR AJAR! Our unique Door Left-Open reminder can be used to alert you to a door or window left open too long! You define the maximum time. Use our SpeakerHub, our audio hub, to play a tone or message, alerting you when a door is opened or left open too long.
- HUB REQUIRED, START SMART: YoLink Hub is the only central controller for YoLink devices, and it connects YoLink devices to the internet and the cloud. Without the YoLink Hub, this smart sensor does not work with the YoLink app and does not support 3rd-party integration with Alexa and IFTTT. Your hub will be compatible with a growing family of smart products for home and business! Search for B09FSS95G9 for a SpeakerHub (our audio, talking hub) or B07TQLKQLJ for the original Hub.
- NOT YOUR FATHER'S DOOR SENSOR! This is a sophisticated electronic device, utilizing the latest technology. 24/7 cloud server device supervision monitors your system for online presence, signal strength and battery level, to ensure it will work when you need it! (Hub required, for full functionality)
- DEVICE-TO-DEVICE PAIRING: a unique feature, two or more devices can be paired together. Even if the internet is out and the power is down, they will carry out their paired actions. Pair your door sensors to a Siren Alarm, then turn it off when you want to "disarm" your system. Use a SirenFob or FlexFob to control your siren. Make your own custom security system!
- DON'T TRY THIS WITH WiFi! LoRa is short for Long-Range. Boasting up to a quarter-mile open-air range, and operating at the 900 MHz band, YoLink devices can be placed where your WiFi probably can't go, such as in basements, separate buildings, even on RVs and boats stored on your property! Prepare to be pleasantly surprised!
- SMART OR STANDALONE, you decide: for full-functionality and the full potential of your Door Sensor, a hub with an internet connection is required. Or, you can use device-to-device pairing to pair your door sensors directly to a siren - you can then manually arm/disarm your siren with a SirenFob (search B0BRCX6HVK). Search B09FSS95G9 for the SpeakerHub, or B07TQLKQLJ for the Original Hub.

After many hours of research, decided to go with the YoLink product line. Purchased the hub, water sensors, water valve controller, couple of the outlet controls, motion sensor, and this door sensor which we put on our garage door. Eliminates the question 5 minutes after leaving home, did we close the garage door?. I can look on the app which tells me if the door is opened or closed. Forget to look at the app, no problem you can set an alert for the system to text your phone after the door has been opened for any specified amount of time. Completely wireless. Just scan the QR code on the product and it connects wireless to the hub. Attached one side to the garage door frame and the other to the door itself, when the two are apart, the door signals as open. The Yolink app is very easy to use, controls everything on the system with a lot of different options. The system sends alerts to your phone, via email or text message. The best part, the app is FREE, no subscription costs. Adding equipment is a breeze, just scan the QR code on the device and it connects wireless to the hub.

Simple to install and works exactly as expected. I recommend it. Buy these in bundles and save. ----------------------------------- Oh... here are a few details about Yolink sensors and hub you really do need to know. All yolink sensors of any type communicate with the hub and the hub communicates with the yolink server and the server communicates with your cell phone and the yolink app. You might think this is bad but I actually love it. Here is why. You link can send you a text or an email if a sensor is tripped. But if that text or email winds up on your phone how do you know it got there? Does your phone make some special beep when a yolink email comes in or a special sound when a yolink text comes in? As for the text I do know how to customize my text to make a special noise but I don't bother. Why don't I bother? Because I set the yolink app to "app only notification". Well ladies and gentlemen.... I found a notification reader app for my phone. It reads yolink notification out loud. Not text, not email but app notifications from the yolink app. It can be set to only read notification from any certain app you want and not from apps you don't want. Get this... it has a time delineation setting.... LOL your thinking WHAT? No it does not delineate time... It delineates THE time the app reads notifications out loud. Here is how I set it, I have it set so the app reader only reads yolink notifications at night. Not during the day time. My wife hates hearing it during the day and evening. During these times the notification make a small sound. I know to check the notification. My wife can't hear it. So get all that? Yolink could have an "in app reader" or "announcement" that could simply say out loud what sensor just got tripped. But yolink wants you to pay them for a text service that can send a lot of text to you. NO... you don't need that. Install the notification reader, it is called "voice notify" version 1.3.1, it is awesome. It truly completes the Yolink system and makes it what it truly should be. A way for your phone to tell you what door or window or yolink sensor just got tripped and it can happen while you are in your easy chair at home, or, in an airport on another continent on the other side of the planet. ~

The YoLink LoRa smart door & window sensor integrates easily with both Home Assistant and Hubitat, making it a versatile option for smart home setups. So far, the sensors have been very reliable and perform better than some of my Z-Wave counterparts. The only downside is that they are not local and rely on the internet, which could be a drawback for some users. If you can work around the web dependency, they offer excellent service, and the YoLink app is user-friendly and intuitive. Overall, a solid choice for long-range sensors with great performance!

Added this door sensor to my existing YoLink system. Item connected to hub without problem and was easy to set up. Also mounted firmly to door and frame with mounting tape on the back of the sensors. Performs as expected. Very happy with the performance and quality of the YoLink line.

I really like the door sensors. They are easy to set up (if your phone can read the QR Code), and the notifications in the YoLink app work great on my iPhone and Apple Watch. You can label the doors (and all sensors) so that you know which one has been opened, is still open, or gets closed. You can even go back and see the history of every alarm (every time the door opened and closed). Pretty sweet! I have several "Homes" set up in the app, so that I can track multiple doors on several buildings, each on a different YoLink hubs. That all works very well. You can even get an email notification if you wish. However, of the dozen or so devices I have from YoLink, I ran into a problem on one door sensor, where my iPhone could not read the QR code on the device, for it was faint, which is a requirement. My work around was to snap a picture of the QR code with my camera, send it to a printer, darken it down, and then scan with my phone. This was a long way around to get the QR code, but it worked. I ran into one other issue where the door sensor fell off the door / wall, but I just got some glue and it worked just fine. Overall I would and will purchase again.
