I work with blinds, windows & door frequently in my setup... It would be great to have a device that represents "open" and "closed" rather than using locks and dimmers.
Some open/close devices may have additional requirements. For example, garage doors and blinds can be partially open. Some may even allow you to set just how open they are. Others are more advanced, such as blinds that open both bottom-up and top-down. Not sure if all of that is necessary in a first pass, but just some things to consider.
