The Z Wave protocol supports barrier devices, some of which are garage door openers.
An instance of one of those devices seems like it would have a DisplayCategory of 'DOOR'. But, I do not see a comparable Smart Home capability.
Nor do I see corresponding Capability Property
I am not sure how to map those devices as a Smart Home devices. I am most concerned about how one would control a garage door using Alexa.
How to interact with devices groups? 1 Answer
