ZWaveVersion (Version) is a child container of a ZWaveDevice, providing it supports the Version command class. Its read-only properties specify the following:
-
Library Type — Numerical Z-Wave library type.
-
Protocol Version — Numerical Z-Wave protocol version.
-
Application Version — Numerical vendor-specific application version.
A right-click action “Read Cmd Class Versions” is also available, which is automatically invoked upon a device discover. This retrieves the information above, as well as the version of each of the device’s supported command classes. These versions are reflected in the ZWaveDevice’s “Node Info”, “Cmd Classes” properties (see Node Info).
