I was able to associate this switch without issue, and it shows up as a binary switch. However, there are additional features that would ideally be available, such as push-button simulation (from open, to closed, and back to open), as well as a timing setting to set the time between state changes.
Other than that, it does actually work - with the exception that changing the state of the button takes too long within the Almond+ (the state changes seemed to back up, to the point that the door opened up a good minute after I was finished playing with it).
