I played around a bit more last night and here’s some more findings:
There’s now the concept of a “Door” which is a combination of a lock and a contact sensor and a “Shortcut” which just displays the state of said combined device. Neither do I have a real grasp on how they relate to apps. Not sure that this existed in the previous update as I got my lock the same day as the update and only briefly configured it.
The status of the “Door” (and it’s corresponding “Shortcut”) is actually broken on the current app for my lock (Kwikset 910, no contact sensor) if you unlock the door it will also say “Unlocking” or “Locked” if you exit back to the dashboard (Devs. are aware, I emailed them).
Overall I wish you could get rid of all the categories they’ve introduced in the new version and return to the simplicity of Apps & Things because they just make the app slow to load, but I know it’s just me being resistant to change at the moment.
