Anthony,
I’m not certain I fully understand your question, but here is how this works.
The micro switch mounted behind the deadbolt strike plate is wired as a normally open switch. When the deadbolt is locked the switch becomes closed. As it is wired to the terminals in the contact switch, that contact switch becomes closed. The ST app shows it as Closed when the door is locked, and Open when the door is unlocked.
I have assigned this particular contact switch to a modified version of the Zwave Door/Window Sensor Device Handler.
I’ve made some progress in having this switch show up in the app as Unlocked or Locked instead of Open/Closed.
I hope this answers your question. I’d be happy to offer more info if needed.
