I second this. The issue is causing the manual lock mode from the bolt turning by hand or button push outside for the Schlage lock to never respond to this event or happens to respond 25 minutes to hours later if lucky. Noticed that if after manually locking it and then use the app to refresh the device it will show the change.

Update:
(Note the Lock Manager they use is currently v1.4)
Modified what was mentioned here and fixed the issue with how it was not posting the notification for manual locking.
