Zigbee Cluster Library Specification 7th Zigbee Alliance by Zigbee Alliance instant download after payment.

This document specifies the Zigbee Cluster Library (ZCL). The ZCL is a repository for cluster functionality that is 1675 developed by the Zigbee Alliance, and is a working library with regular updates as new functionality is added.
1676 A developer constructing a new application should use the ZCL to find relevant cluster functionality that can be 1677 incorporated into the new application. Correspondingly, new clusters that are defined for applications should be 1678 considered for inclusion in the ZCL.
1679 The ZCL consists of the ZCL Foundation, a set of elements that apply across the entire library (such as frame 1680 structures, attribute access commands and data types), and a number of sets of clusters. Clusters that are generally 1681 useful across many application domains are included in the General set. Clusters that are intended for use mainly in 1682 specific application domains are grouped together in domain oriented sets.
