I don’t think Rboy has a smartapp that still works, does he? (All the old groovy based smartapps stopped working during the platform transition last year.)
Do you have the new Rboy “edge driver“ for locks? And are you sure your lock is using it?
Here’s the thread about the edge driver:
[EDGE] Universal Enhanced Z-Wave Lock Driver for Schlage, Yale, Kwikset, IDLock, Popp, Danalock, August Pro, Keywe, Philia, Samsung
You can see which edge driver the lock is using at the official web interface to your SmartThings account
