You could use custom app settings or pairing page (html). For device settings it seems not to be possible.
An info tabstrip or a link to a manual page with images for each device in the app settings would be my best approach.
The first scrennshot are device settings => default generated screen.
The other screenshots are app settings => html where you can define imput fields and store the values in app settings. You can extend the html page with further information.
I don’t know much more than listed in the developer documentation (see link in my last post).
As I could see there, html is not possible in device options.
