Our long-range coverage enables its use in areas challenging for most residential Wi-Fi systems, such as basements, outside porch/patio areas, sheds, free-standing garages, even remote outbuildings in your property.
Universal: Easy-to-add functionality to upgrade your existing garage door opener. Compatible with door openers manufactured after 1993 that utilize photoelectric sensors; Please check compatibility on the description before purchase
Low-Power Means Longer Battery Life: On account of the low power consumption, YoLink Garage Door Sensor’s batteries may last 5 years or more (depending on application and device usage/activity), on standard AAA Alkaline batteries (lithium batteries not required)!
Early-Warning Notifications: Receive real-time early-warning notifications in the type of smartphone banner alerts, limited SMS/text messages, and emails, each and every optional and configured per your needs. Please note: YoLink Garage Door Sensor does not alarm or chime, it only sends notifications; For an audible alarm, imagine our Siren Alarm
Doesn’t Work without YoLink Hub: YoLink Hub is the only central controller for YoLink devices, and it connects YoLink devices into the web and the cloud. Without YoLink Hub, this garage door kit does not work with YoLink app and does not toughen 3rd-party integration with Alexa, Google Home and IFTTT.
