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.

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.
  • 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!

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.
  • Batteries included! Two AAA batteries, good for 2+ years standby, are included!
  • 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.
