[EDGE] Universal Enhanced Z-Wave Lock Driver for Schlage, Yale, Kwikset, IDLock, Popp, Danalock, August Pro, Keywe, Philia, Samsung

This is device type handler (DTH), i.e. it allows SmartThings to access/control the features of your lock through SmartApps.

Apps like LUM provide many advanced features for lock management and user programming. You can use a SmartApp like CoRE or WebCoRE to issue commands to the DTH to create your own custom scenarios.
In your case you would be issuing the commands enableOneTouchLock and disableOneTouchLock to enable/disable the Schlage lock n leave feature. You can refer to this post for more details on how to use CoRE/WebCoRE to trigger the above commands when a user pin code is detected to unlock the door.
