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 con-
sumer 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.
The network indicator feature will display two key elements of communications health characteris-
tics.
• Communication Hardware Status: Information about AMI radio communications, HAN
(ZigBee) radio communications, and the interactions between the two
• RF Mesh Neighbor Status: Information about the number of RF mesh neighbors available
for network communications
For more information on this feature, see “Appendix D. Gridstream RF Network Indicator” in
Landis+Gyr RF Generation 5 (G5) Integrated FOCUS AXe Endpoint User Guide, publication num-
ber 98-2411.
Power Outage/Restoration
When an outage occurs, the meter uses an early power failure signal to alert the communication
module to disconnect from the meter's power immediately. The communication module saves criti-
cal module data to non-volatile memory and creates and sends a power outage message. This mes-
sage includes the following information:
• LAN ID
• Outage time
• Reboot count
The communication module sends the message, then assists with routing other packets until the
back-up energy source can no longer keep the radio alive.
When power is restored, the communication module connects with the network. With network com-
munications restored, the communication module sends a power restoration message that includes
details such as:
• LAN ID
• Outage time
• Restoration time
• Reboot count
