ZWave Command Classes

Revision as of 21:33, 19 May 2013

On a ZWave's properties you'll find 2 values to show what the device can do (values in decimal):

Capabilities 	209,140,0,4,17,1,L,R,B,RS,|38,39,112,114,115,117,134,
Version 	6,1,91,3,11

The first six numbers in capabilities are reported by the ZWave ZW_GetNodeProtocolInfo function (0x41):

Capability
Security
Reserved
Basic Device Class
Generic Device Class
Specific Device Class

These flags are determined by the bit patterns found in the two bytes: Capability and Security:

L  : Listens
R  : Routes
B  : Beams
RS : Routing Slave
W1 : Requires beaming

If the Capability is >= 128 then the device listens for commands, otherwise it's a battery operated device that only wakes up occasionally.

The version is what's reported by the COMMAND_CLASS_VERSION command VERSION_REPORT. There are 5 values: Z-Wave Library Type, Z-Wave Protocol Version, Z-Wave Protocol Sub Version, Application Version, Application Sub Version. The Application version is specific to the device and not defined by Z-Wave.

The library types are:

CONTROLLER_STATIC  1
CONTROLLER         2
SLAVE_ENHANCED     3
SLAVE              4
INSTALLER          5
SLAVE_ROUTING      6
CONTROLLER_BRIDGE  7
DUT                8

The protocol version and sub-version are the version of the Z-Wave library, and they are listed here: ZWave Protocol Version

After the '|' in Capabilities are the supported command classes, which are as follows:

Alphabetical

Numeric
