Are you using a custom DTH?
The lock is definitely compatible with ST (and popular)
If you have access to RBoy apps try using this app to manage your lock and users: [RELEASE] Lock User Management - Door lock code manager (create, delete and schedule codes) with automatic lock/unlock, custom user actions and SHM/ADT integration (LUM)
Ideally you should only use the stock ZWave Lock DTH or this custom DTH which is compatible with smart locks.
