Features

  • A SMART START! Everything you need to get started: one SpeakerHub, our unique, audio, talking (text-to-speech) hub, and (3) Door Sensors. Batteries are included and preinstalled, good for up to 5 years between battery changes. 2.4 GHz band, only, required. Supports 300+ devices from our full product line. Add more hubs for large homes, high-rise condo buildings, etc.
  • LET'S HEAR IT for SpeakerHub! Your SpeakerHub can play from a library of sounds and tones, from a chime tone to a burglar alarm siren. It can even play your uploaded MP3 files! But never before has your hub talked to you! Now, hear your important messages in clear text-to-speech messages. Let it read out the standard alerts, or customize the message; it's up to you!
  • 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!
  • 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!
  • MORE THAN JUST A DOOR ALARM! Place a sensor on each exterior door and window to 'Protect Your Perimeter' Activate and control lighting. Place a sensor on your fridge/freezer door or lid and know if it was left open, to prevent food loss. Track activity in your home or business. Keep an eye on children and elderly loved-ones. Use the sensors to protect liquor & medicine cabinets, gun safes, storage lockers & boxes.
  • 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.
  • 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!
  • Whats Included: This package includes 1 YoLink Hub and 3 Sensors4 items total. The Number of Items: 4 refers to the four individual products in the package, not four sensors.

  • Easy Setup, Powerful Monitoring Capability, Quality Equipment
Style: With Hub
We have a family member with alzheimer's, that wanders at night, and sometimes will trash other rooms in the house. Now my wife can be notified when her mother's door opens or closes and can go downstairs to help her get back in bed. Notification options on this system is superb: SMS messages to phone, the hub speaker sits next to my wife's bed has a choice of alarm sounds--in addition a verbal message "Kathy's door opened", "Kathy's door closed. There is even a "Do Not Disturb" option, where you set a range of time that the device reports door activity. For example, we want to monitor the door only during the night, 10:00pm to 5:00am. A volume control allows you to set just the right volume. For critical alerts, one can enable a loud siren. There are a number of different sensors, such a detecting a water leak, and others I haven't looked at yet. The door unit and hub speaker (that connects to the Internet) will notify you whether you're at home or miles away. These units are packed full of features that I haven't even explored yet. I'm very pleased with this purchase! ... show more

  • Product OK Support from Amazon and Seller not good
Style: With Hub
Updated: Ordered product with base and 3 remote units, but I only got 2 remotes. Amazon says seller needs to provide additional remote, Seller says Amazon needs to provide. Update - Seller reached out and after previous lower review and apologized for getting the run-around and initial poor support. Seller made it right, updating to 5 Stars only due to quality of product. So far I am very pleased with the product it has solved a need to monitors doors left open or not closed all the way. The app is fairly intuitive for someone in the IT industry looking for ability to manage rules. Alexa app integration is OK, however it is missing the ability on these sensors to alert if door is open for longer than XX minutes, I have to use the YoLink hub only for that. ... show more

  • I know when my kid wakes up and opens his door immediately.
Style: With Hub
If my son wakes up in the night or morning before me we opens his door and my pre recorded message plays in my room and I am able to intercept him before he wonders where we are. Great for kids or elderly who may wander out of doors.
