Change on and off to open and closed?

I am using a Z wave plug to operate a door. Basically the door is plugged in to the Z-Wave plug. When the on command is sent the door will open and when the off command is sent the door will close. I have been struggling to find a way to change the status listed for that Z-Wave plug. By way of example instead of the status being on I would prefer it to say open and instead of off I would prefer closed. Does anybody have any idea on how to make that Z-Wave plug status reflect open and closed? I assumed it was in the device handler section of the IDE.
