I wanted to add a few comments to this thread about the Ecolink Garage Door Sensor. I’ve added it to one of my two garage doors - working perfectly fine. However - as others have noted - on my Android device…no notifications of sensor open/close. Oddly - my wife’s iOS device (Apple iPhone 8) DOES send notifications via the app of sensor open/close. I’ve checked the Ring app for both of us and both are set exactly the same.
Is it possible that Ring has modified the iOS app to show the notification but not, yet, for the Android version - ???
