This release occurred on December 22, 2023.

Compatibility

• Minimum required meter firmware 10.5.769

• Maximum required meter firmware 10.5.999

New features and enhancements

Support for a new alarm type

Earlier AppServ (and DI) versions supported events and alarms. Events are sent to the head end system during interrogation; alarms are sent to the head end system immediately and then re-sent during interrogation. The new one-shot alarm type is sent to the head end system immediately but is not re-sent during interrogation. The one-shot alarm type supports forthcoming DI applications.

DI Data Cloud

Adds support that allows for an application to transfer metering data to an Itron server using an internet connection and a local Wi-Fi connection.

Data transfer limits

To enable improvements in outcomes applications, AppServ application data transfer limits have been modified.

Known issues

AppServ has no known issues at this time.

This release occurred on January 30, 2023.

Compatibility

• Minimum required meter firmware 10.5.769

• Maximum required meter firmware 10.5.999

New features and enhancements

Removal of DI agents from containers

Agent removal initiated by the EAC is now supported. Enhancements included in an upcoming EAC release will complete the requirement that allow total agent deletion.

AppServ distinguishes DI Dev Key (DDK) meters from production meters.

A DDK meter is manufactured with a script injected into it that allows the meter to run third-party DI agents without licensing requirements. When a developer initially uploads their agent to the EAC an automated process calls the Application Management Service (AMS). The AMS dev signs the agent, giving the agent the DDK signature and allowing the agent to run on the meter. With AppServ's recognition of the DDK meter's dev keys, third-party development is made more convenient by bypassing licensing requirements.

Known issues

AppServ has no known issues at this time.

This release occurred on December 6, 2022. This version is bundled with firmware differential update package 10.5.750.

For customers installing the 10.5.750 differential firmware upgrade, AppServ 1.7.402 and the Home Area Network (HAN) agent both complete installation when the firmware upgrade completes.

For customers receiving new meters from the factory (with the 10.5.750 firmware included), a six hour waiting period must pass before AppServ 1.7.402 completes its installation. The meter's HAN agent installation completes six hours after the AppServ installation completes.

Support for DI's new Peer-to-Peer (P2P) technology

AppServ provides the primary mechanisms for cross-agent communication, including security and protection for data transmission. DI peer-to-peer (P2P) is a technology that allows agents on DI meters to exchange encrypted data packets between agents on the same meter and other meters before it is transmitted to an application or HES. AppServ's new functionality to support this includes enhancements and policy file implementations to:

• Provide agents connectivity information for radio-frequency (RF) and power-line carrier (PLC) networks

• Store P2P diagnostics statistics about each agent feature for troubleshooting

This release occurred on December 30, 2020. This version is included in the Gen5 Riva Singlephase Electricity Meter's firmware 10.0.731.

For the DI GenX GSR 1.2 system release, AppServ is a new feature that is distinct from device firmware.

As the primary interface between the Agent API and DI agents, AppServ provides communication through subscriptions and delivers data separation and access through use of permissions. These changes bring increased data security and allow utilities to implement DI API changes at a faster rate than can occur with system releases. While many of these changes are implemented through use of the new DI Policy, AppServ enforces the policy file resource management definitions by:

• Reporting DI Policy violations to the App Store Platform

• Storing DI Policy violations in statistics digests

• Applying the default daily limit for agent-specific outcome and upstream data limits

• Applying the default daily limit for agent-specific agent director alarms

AppServ enforces data separation and access by:

• Controlling access to meter/endpoint identity data, agent data, metrology data, and the metrology data message queue

• Allowing or disallowing agent director data upstream based on permissions

• Limiting agent applications to read and subscribe to only meter and metrology data

• Implementing change request registration, activation processes, and validation of agent application identity

AppServ packages can be updated on Gen5 Riva Meters using FDM Tools' Manage Agent Images operations. For more information on updating Gen5 Riva Meter DI packages, see the most up-to-date version of the Field Deployment Manager Tools Mobile Application Guide.
