First steps with SmartThings: setting up Yale YRD256 smart lock

If you’re using the built in SmartThings SmartLocks app you should be able to see the history of codes being used from within the app itself under the History tab. It used to provide push notifications earlier but I believe that it no longer does it and I don’t think there’s no way to configure it from within SmartLocks.

If you have access to RBoy Apps, you can try out the Lock User Management (LUM) app which allows you to customize notifications (push and/or SMS) for individual users along with a host of other features. LUM is compatible with SmartLocks so you can use both simultaneously; review lock states, users/look at usage History through SmartLocks while creating custom actions, notifications and user schedules/types through LUM.
