Thank you so much . I was able to do exactly what you said , it said one device deleted. I was able to add it back , but this time it added it as Linear Garage Door and also gave a warning about latest z-wave security compatibility and not to use it in secure locations. Changed the battery of the sensor , re-paired it by pressing the link button seven times. Not sure if i needed to do this but for some reason it wasn’t detecting if the door was closed or open. Powered off and On the Iris controller and now i am good to go. Your help is greatly appreciated
