This was a recent change from SmartThings. At this time I think the two options to get this lock programmable through SmartThings are:
- Install the Enhanced Z-Wave Lock device handler (which compensates for the lock firmware issue), then pair the lock and it will automatically be assigned the device handler.
- Pair the device without any custom device handlers and then manually update the device handler in the IDE to Z-Wave Lock. Keep in mind some users may experience dropped/missing notifications since the lock firmware bug was the underlying reason why the lock was dropped from this stock device handler. This can be partially improved with the addition of buffering devices.
Unfortunately both require some effort on part of the user/installer. Schlage doesn’t have a history of creating firmware updates and if they do it’ll most likely be available for new locks, since ST cannot push z-wave firmware (or you can purchase a separate Z-Wave stick and programming software to update the lock firmware when available).
