I think there's special integration for home automation. I have the same switches. Remember when you first set them up and you had to go to a special "Smart Home" section of the Alexa app? There's a special section there just for that stuff.

I'm not sure if that part is open to developers or not. It looks like it is. There's a "Get More Smart Home Skills" button that shows 59 options, so it's probably not just for the big boys.
