Hi there. We’re continually working with SmartThings to keep our SmartApps and Device Handlers up to date with the latest changes. A couple of quick notes:
- LUM and RLA work with the stock Z-Wave Lock and ZigBee Lock device handlers
- The Universal Enhanced Z-Wave lock DTH is optional but recommended since it gives you access to more lock features and also fixes bugs with the stock DTH’s and has workarounds for defects in some lock firmwares as explained here.
