• Messaging server - Sends messages to a customer through ZigBee network.
Messages can require confirmation from the customer.
• Metering client - Reads the metering usage data from meters on the network.
The client side clusters receive the events and act on them; for example, a thermostat
may receive a published price event for electricity and change the heating setpoint to
save money. The gateway makes these events available on the internet for other
devices to act on, or for reporting purposes. The In-Premise Display Smart Energy
device type supports the following clusters:
• Time client - Synchronizes real time clock with the time server on the ZigBee
network.
• Demand Response / Load Control (DRLC) client - Receives DRLC events from
the server and reports them through iDigi. The gateway handles canceled and
overlapping events and provides updates when the currently active list of events
changes.
• Price client - Receives price events for all available commodities from the price
servers. The gateway also tracks when the prices of commodities change and
provides updates through iDigi.
• Messaging client - Receives messages from the server and reports them
through iDigi. The gateway allows users to confirm messages, handles canceled
messages, and provides updates when the currently active message changes.
• Metering client - Reads the metering usage data from meters on the network.
