Which Schlage Connect Lock Device Type Handler to use as a baseline?

[RBoy (www.rboyapps.com - Making SmartThings Easy!)]

I think it’s a combination of SmartApps and DeviceTypes that will achieve all that needs to be achieved. The handlers out here are pretty good, similar and stable. I’ve specifically written mine to fix a few bugs in the base ST code (which should also be reverse integrated into the stock ST code in the next week or two) and designed the handler to achieve the above scenarios (plus more based on user requests) in combination with some SmartApps. A casing example is this SmartApp:

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

A “future proof” Universal Enhanced Z-Wave Lock driver This driver is enhanced to fix bugs in the stock ST ZWave Lock driver, include patches for bugs in lock firmwares and bring out additional features for Schalge, Yale, Kwikset, IDLock, Popp, Samsung, Delaney, August Pro, Danalock, KeyWe, Philia, Vivint, Locstar etc zwave locks (see below for a full list of models and features). This works with all ZWave locks and newer ZWave Plus locks (see below for a list of locks tested). It discovers/learns the lock features and automatically configures them. If a feature is not supported by the lock it will not show up or say Unsupported. You need SmartThings Smart Lock Guest Access (SLGA), Advanced Web UI or a SmartApp like Lock User Management (LUM), Rental Lock Automater (RLA) to program user …

The “Schlage Alarm Mode” SmartApp which leverages those Alarm features and interacts to configure them based on rules.

To your point exactly, is now to build further on those rules to add more features, e.g. you would use a combination of these SmartApps I’ve written coupled with Rules Machines to make every scenario listed above.
