ZWave API

Introduction

The ZWave API is not available for free. You have to get the Zensys SDK for command specifications and device class definitions. This page tries to collect all the freely available information about ZWave. The final goal is to provide a header file with all necessary definitions for basic operation with open source software.

IMPORTANT: all information added to this page _must_ have a reference to the source where it came from.

API

Frame specification

Karl Denning implemented basic ZWave support in his software "HomeDaemon". He advised that basic frame specification can be derived from his source code (http://www.intouchcontrolsforum.com/forums/showpost.php?s=e11a812b08256225ebb66a73d8f6d193&p=173&postcount=13).

Basic Classes

From the Leviton Z-Wave RS232 ASCII Interface Programming Guide (RZC0P-1LW, 10/9/2007):

Controller         1
Static controller  2
Slave              3
Routing Slave      4

Command and Device classes

From the Electronic Solutions, Inc. DBMZ Advanced User manual:

Command/Device Classes

Multilevel Switch

• COMMAND_CLASS_SWITCH_MULTILEVEL

MULTILEVEL_SWITCH_GET
MULTILEVEL_SWITCH_SET
MULTILEVEL_SWITCH_START_LEVEL_CHANGE
MULTILEVEL_SWITCH_STOP_LEVEL_CHANGE

Basic

• COMMAND_CLASS_BASIC

BASIC_GET
BASIC_SET

Multilevel Sensor

(from the Vizia RF Application Note)

• COMMAND_CLASS_SENSOR_MULTILEVEL

example get:

>N4SE49,4 (RZC0P Syntax)

sensor report:

<N004:049,005,001,009,075
  049: device class
  005: command report
  001: value send is a temperature value
  009: value represented with 1 byte in degrees fahrenheit 
  075: 75° F

Manufacturer Specific

• COMMAND_CLASS_MANUFACTURER_SPECIFIC

Show the ESI product data:

MANUFACTURER_SPECIFIC_GET

Example return message:

0x00 0x33 0x52 0x50 0x30 0x32
 0x00: maunfacturer id high byte
 0x33: manufacturer id low byte, ID: 0x0033
Product type ID "RP"
Product ID "02"

Version

• COMMAND_CLASS_VERSION

VERSION_GET

Example return message:

0x04 0x02 0x06 0x01 0x01 0x5a
 0x04: Library type 4 for basic slave device
 0x02: Protocol version 2
 0x06: Protocol sub version 6
 0x01: Application version 1
 0x01: Application sub version 1
 0x5a: ?

All Switch

• COMMAND_CLASS_SWITCH_ALL

SWITCH_ALL_GET
SWITCH_ALL_ON
SWITCH_ALL_OFF

Configuration

• COMMAND_CLASS_CONFIGURATION

Each parameter is a single byte ("0" or "1")

CONFIGURATION_GET
CONFIGURATION_SET

Power Level

• COMMAND_CLASS_POWERLEVEL

POWERLEVEL_TEST_NODE_SET
POWERLEVEL_TEST_NODE_GET
POWERLEVEL_TEST_NODE_REPORT

Example: POWERLEVEL_SET, 5, 60 set the ZWave node's power level to 5 for the length of 60 seconds
