Figure 4. ZigBee Communication
Using Command Center, the utility sets up the HAN remotely via RF network via a provisioning
process. The utility registers each device and a security handshake occurs to ensure protected and
closed communication between the meter, endpoint and energy devices in the home.
The utility sends downstream pricing information and text messages via Command Center (or 3
rd
party integrated application) to the module, which uses the ZigBee radio to push down the
information to the devices. Because the solution is bi-directional, the devices are also pulling meter
data and accurate time that is maintained at the endpoint.
The Gridstream RF G5 FOCUS AXe module refreshes data from the meter every 30 seconds and
makes it available to all the devices. The endpoint makes available kWh values (delivered only) up
to five dial resolution and instantaneous kW up to 99.999 for display. It supports up to five
provisioned devices and makes available five tiers for pricing events to align with the meter's
number of rates.Text messaging is limited to 80 characters.
 NOTE: ZigBee radio devices are consumer products and should not be considered part of a
mandatory load control program, nor a replacement for viewing energy consumption with the same
accuracy found on the meter display. The utility will need to conduct some training of both internal
personnel and consumers of the capabilities and limitations of HAN technology.
ZigBee radio devices will need to be programmed to respond correctly to each pricing event or Time
of Use rate from the meter. An in-home display like the ecoMeter, for instance, will request energy
and instantaneous demand data every 7 seconds. It will also request price, which will be provided as
flat or Time of Use (TOU) depending on how the meter is programmed. When it sees the meter has
changed to Rate B, for instance, it may respond by changing the back lighting to indicate to the
consumer that the price of energy has increased.
Gridstream RF Network Indicator
This feature provides a ‘communications health’ view of a Gridstream RF enabled electric metering
endpoint on the LCD display of the meter. This health check information can be utilized during field
installation or troubleshooting activities to validate status of the Gridstream RF electric endpoint,
and provide key inputs to any communications issues that may be encountered from time to time.
