How to control Schlage locks in new ST app?

You can safely use the Classic app for now (using your same Samsung credentials) and it’ll open up many new features and custom lock controls which aren’t there as yet in the new ST app.

Smart Locks on the Classic app is a nice app for basic user management, add and delete (if you forget your code you’ll have to delete and recreate a user).

If you’re looking for more advanced controls (like taking actions when a user uses a code or how they used the code, from inside/outside/remotely etc) or custom user types (expiration, one time, scheduled, presence etc), you will need custom apps like this one (if you have access to RBoy Apps):

This app also works with the new ST app and shows up under the Automation tab (once installed through the Classic) so you can control/manage your users from there.
