Device Types#
ZGP includes the following device types:
Device Type | Description |
|---|---|
Green Power Device | A self-powering, energy-harvesting device that implements the Green Power feature. These devices communicate using a compact message format and all messages are one-way (out only). GPDs are not end devices and cannot receive commands. |
Green Power Proxy | A fully-compliant Zigbee device, which in addition to the core Zigbee specification also implements proxy functionality of the Green Power feature. The proxy translates ZGP frames to Zigbee Cluster Library (ZCL) frames and acts as an intermediate node between the GPD and sinks on the Zigbee network. For more information on ZCL, see Zigbee Fundamentals. |
Green Power Sink | Any device that can be controlled by or receive data from a GPD (for example, a light or a server device). A GPS can only be implemented on a standalone ZED. |
Green Power Combo Basic (GPCB) | A combination device that only implements the basic GP combo functionality, for both sink and proxy within a single device. |
Green Power Proxy#
GPDFs are specialized frames, unique to GP. The frames are encapsulated within a ZCL packet for transmission across a Zigbee network. The proxy acts as a conduit between the GPD and the sink. During the commissioning of a GPS and GPD, an entry is added to the proxy table to act as a mapping between the GPD and the sink. When a GPDF is received, the proxy may look up the sending GPD in its proxy table to determine the sink or group to forward the GPDF to.
Note: Because the proxy is merely forwarding the GPDF to its intended destination, it is agnostic about the GPDF data payload.
Green Power Sink#
A Green Power Sink is a fully-compliant Zigbee device, which in addition to a core Zigbee specification also implements the sink functionality of the Green Power feature, basic or advanced. The sink is thus capable of receiving, processing, and executing GPD commands, tunneled and optionally also directly received. For more information, refer to ZigBee PRO Green Power specification, Basic functionality, set Version 1.0 (ZigBee Document 16-02607-024).
Green Power Combo Basic#
A Green Power Basic Combo implements the basic set of proxy and sink functionality, as well as selected server-side and client-side attributes per the ZigBee PRO Green Power specification, Basic functionality set, Version 1.0 (ZigBee Document 16-02607-024).
