YoLink Smart Garage Door Sensor, Garage Door Position Sensor with Door Left-Open Reminders, Alexa, Google, IFTTT, Home Assistant (Hub Required)

“YoLink” is a proprietary wireless technology provided by YoSmart. which is based on Semtech’s LoRa wireless technology combined with the YoSmart smart home/building protocol, to provide the most advanced smart home/building devices solution. Compared to WIFI, Bluetooth, ZigBee, Z-Wave, and other smart home protocols, it has the advantages of low-power consumption, long-distance coverage (wall penetration), and anti-interference. It is the first smart building/home protocol that can be very easily set up and is a very low cost but creates a reliable, robust, and more secure IoT network. Requirements: 1. A YoLink Hub (sold separately, used to connect YoLink Outdoor Motion Sensor to the internet and the Cloud). 2. A smartphone or tablet running iOS 9.0 or higher, Android 4.4 or higher. ⭐ You are at risk of intrusion through your garage door, especially if your vehicles with garage door buttons are parked outside! The YoLink Garage Door Sensor allows you to monitor the status of your garage door, from anywhere at any time. You can “arm” the door on a schedule or as part of a scene or on-demand, to protect you and your family while you sleep. ⭐ inform you if your garage door is left open too long. Set a duration that is the most you want the door left open, set times of day that you want to be notified, and never worry about forgetting to close your garage door again! ⭐ features allow you to ask Alexa or Google if the door is opened or closed. The sensor is also compatible with IFTTT.com and Home Assistant. ⭐The Garage Door Sensor can be used by itself (a hub is required) or integrated with one of our smart garage door controllers (that control your existing garage door operator). Start with just door monitoring, and add door control later! ⭐A YoLink hub is REQUIRED for full functionality, including for the app to work, but your hub is compatible with a growing family of smart products for home and business!
