Z-Wave Device Class Specification

　　This document describes the device classes that must be used when designing and implementing Z-Wave™ products. The document also contains a description of the command classes and associated commands that must be used by Z-Wave products when communicating with each other. A subset of command classes is typically mandatory for a given type of device. All commands are handled by the application layer of the Z-Wave protocol. A certification program based partly on self-certification and partly on 3rd party certification is put in place to enable manufacturers to get their product Z-Wave certified in order to ensure interoperability and get permission to carry the Z-Wave logo on the product. Interoperability is the successful interworking of multiple products from multiple manufacturers， for multiple applications， that may be based on multiple versions of Z-Wave. For details about the certification program refer to 0. In case the current device and command classes described in this document do not sufficiently support the product to be developed， please contact Zensys to initiate the required development process. For details about the device/command class development process refer to ［2］。
