This Thread is very old and I don’t know if the code in it still works. But a new device type handler was just contributed to the community recently which exposes all of the Z wave capabilities of a device, so it might be of help.
https://github.com/codersaur/SmartThings/tree/master/devices/zwave-tweaker
This is a device handler to assist with interrogating and tweaking Z-Wave devices. It’s designed for end-users who want to tweak their devices and for developers who want to quickly discover and report the functionality of new devices. It is intended to temporarily replace a device’s normal device handler.
