I feel like Android (the app/sensors) should listed with Integrations, at least so far as being there the way the iOS app is listed with a redirect to the site for the companion apps. When I’m wanting to do something specific with the app and go to look for documentation, my first inclination is to go to integrations, but it’s not listed there and I have to spend several minutes digging around just to find the documentation for it.
It is listed there under mobile app.
I don’t know how the iOS-app is listed but the Android companion app is listed just as you described. You should have a tile with the title “Mobile App” and a list of devices and if you click on a device you get the link to the entities and the three dots icon leads you to the documentation link.
You put it better than me
