Application Endpoint #242 – ZigBee Green Power
This endpoint provides the ZigBee Green Power feature according to the 2015 edition of the
specification, i.e. including support for Green Power Devices with IEEE EUI-64 and bidirectional
commissioning. The ZigBee traffic between Proxies and Sinks utilizes standard ZigBee foundation
paradigms and the ZigBee Cluster Library [R4]. You may use the standard ZCL frames to enumerate,
read and write attributes, invoke commands, etc.
The application endpoint exposes the following clusters:
Cluster
Direction
Description
0x0021
Inbound
(Server)
ZigBee Green Power Sink
Allows pairing the dimmer with ZigBee Green Power switches. The sink can directly receive
Green Power frames but can also utilize proxies in the network.
0x0021
Outbound
(Client)
ZigBee Green Power Proxy
Allows sinks on the network to configure this device as a “Proxy”, i.e. access point for ZigBee
Green Power Devices into the ZigBee mesh network.
7.8.1.
Green Power Cluster (Server)
The server-side of the Green Power cluster provides the ZigBee Green Power Sink functionality, i.e.
provides the ability to process Green Power frames. The device can receive those frames directly if
they are in radio range; or it can process frames tunnelled over the ZigBee network via other Green
Power Proxies. This implementation supports unidirectional and bidirectional
26
GPDs.
