CONNECTPORTX2FORSMARTENERGY

Description

The Digi ConnectPort X2 for Smart Energy is a gateway on a Smart Energy network that

provides secure access to a ZigBee Smart Energy network over the internet. The

gateway is set up to take advantage of connection management services offered by the

iDigi™ platform, and to intelligently handle SE events in order to reduce the need for

communication and micro management by utility applications.

There are three Smart Energy certified software applications for the gateway on the

ZigBee network:

Name Smart Energy Device Type Node Type

ESI Coordinator Energy Service Interf

ace (ESI) Coordinator / Trust Center

ESI Router Energy Service Interf

ace (ESI) Router

Aux Gateway In-Premise Display (IPD) Router

All of the configurations use the same core Python SE_Framework codebase and share

much of the same functionality. The difference between the node types are as follows:

• Coordinator - Forms the Smart Energy network and acts as the trust center. All

devices joining the network must be authenticated with the trust center.

• Router - Joins the Smart Energy network through the trust center. Typically, a

Smart Meter will act as the trust center on the network.

The Smart Energy device type determines whether Smart Energy clusters supported by

the gateway are servers or client

s. The ESI is defined by Smart Energy to support the

server side clusters. These clusters create and cancel Smart Energy events; for

example, publishing the price of commodities like electricity on the network. The Energy

Service Interface supports the following clusters:

• T

ime server - Synchronizes real time clock for all of the devices on the ZigBee

network.

• Demand Response/Load Control (DRLC) server - Manages DRLC event

which can change temperature set points on thermostats, water heaters, and spas

or turn off devices in the home to prevent brownouts during high peak energy

situations.

• Price server - Manages pricing events that set the price of different commodities

using a start time and duration in one minute intervals. For example, increasing

the price of electricity during peak hours in the evening and decreasing price
