10. HAN Account Management Functional Specifications The HAN Account Management processes describe how HAN Permissions are granted/revoked to users in the Portal. The HAN Account Management business rules describe how HAN Permissions are granted/revoked at the entity level.

12. HAN Device Provisioning and Deprovisioning Functional Specifications The HAN Provisioning processes describe how authorized users provision and deprovision HAN Devices through the Portal and how the Portal handles the different statuses of a provisioned Device. The processes also describe how authorized users are able to view provisioning information through the portal.

13. HAN Device Status Descriptions

14. HAN Device Messaging History This HAN Device Messaging History describes what the authorized user will be able to do through the UI, which is simply the ability to retrieve message acknowledgments (message log) for a particular message type, DUNS and message creation date.

20. HAN Messaging Examples Load Control Messaging Temperature Set Point The following example illustrates how to send a load control message to set the cooling temperature setpoint to 30 deg C (3000 in the example below) and the heating temperature setpoint to 15 deg C (1500 in the example below). Since the start time has been set to 2000-01-01T00:00:00Z, this load control event will be started immediately for a duration of 30 minutes. All HAN Devices, regardless of the utility enrollment group they are assigned to, will receive the event as the Utility Enrollment Group in the load control event has been set to 0. Duty Cycle is 255 or NULL which means that the load control switches will not react to this load control event. 12348911 2000-01-01T00:00:00Z 30 0000111111111111 0 1 3000 1500 255 0

21. HAN Device Messaging API

22. HAN API Starter Kit The HAN API Starter Kit is a soapUI-based tool that SMT has developed that Retail Electric Providers (REPs) can use for invoking the Smart Meter Texas (SMT) Home Area Networking (HAN) Web Service interface.

23. HAN API Starter Kit Overview of Steps for using the Starter Kit Set up the Starter Kit Configure SSL Configure WS-Security Invoke Web Services

24. HAN API Starter Kit HAN Provisioning and Messaging WSDL Files After the REPs have integrated with SMT HAN API’s using the API Starter Kit, the WSDL (Webservice description language) files for HAN related services will be provided by SMT upon request. These files can be utilized to build client applications to consume the SMT services for HAN. SMT will provide the WSDL files for the HAN services listed below. HAN Device Provisioning / Deprovisioning HAN Device Utility Enrollment Group HAN Device Messaging which includes: Sending simple text message Cancel simple text message Sending price signal Sending Load control event Cancel a Load control event Cancel all Load control events The REPs are expected to raise a request with the SMT help desk (Call 1-888-616-5859) to request these WSDL files. SMT technical team would provide the WSDL files in a compressed (.zip) file. The WSDL files can also be imported to SOAP UI tool to create and setup the project to access the service.

25. HAN Interface Security Prerequisites for Interfaces · All communication to SMT from REPs and TDSPs will be over 2-Way Secure Sockets Layer (SSL). For each TDSP, a VPN channel has to be established between SMT and TDSP systems. In the case of TDSPs, SSL will be employed over a virtual private network (VPN). · For API requests from TDSPs, SMT requires that a user credential be passed in a SAML token that is part of SOAP header. The specific of SAML token is described in a later section. · For API requests from REPs, SMT requires that a user credential be passed in a UserName Token that is part of SOAP header. SMT does not require password to be passed as part of UsernameToken.

26. HAN API Authentication and Authorization

27. HAN Device Testing Criteria Note: Verify that TDSPs have processes in place to support HAN Device Testing with REPs and HAN Device vendors. The TDSPs provide a standardized method of testing and verifying HAN Device functionality to ensure that HAN Devices function as designed within the specifications detailed in the Smart Energy Profile 1.0 when operated on TDSPs advanced metering system (AMS) network. The REPs and HAN Device vendors should contact the TDSPs to initiate request to perform HAN Device testing. The HAN Device test cases that are executed during the ZigFest Interoperability events are the basis of the test cases executed by the TDSPs in their HAN Device validation program. Some TDSPs have more test cases, and some have less, but all are based on the ZigFest test cases. These include provisioning, deprovisioning, and messaging (simple text, load control and pricing). The TDSPs record the testing results and provide feedbacks to the REPs and HAN Device vendors that requested the tests.

28. HAN Interoperability Report The HAN Device Interoperability Report contains information regarding HAN Devices that have passed testing at a particular TDSP. The reports are updated monthly and filed with each TDSP's Commission report. Each report contains the device name, version, meter firmware version, device configuration and date tested. Devices that are in testing or have failed testing are not on this list.

30. Next Steps Working with Handbook and Education taskforces to review and fine- tune the HAN Guide – Method to incorporate the HAN documentation into the HandBook – Going forward Process & Procedures to interface HAN documentation, future versions, with both Task Forces group efforts – Education Process to advise the market of the HAN documentation availability, location and access method – AMIT steering committee to determine who in the market can have access to the HAN documentation – Will we provide a soft copy, hard copy or both available to the market Gather feedbacks and comments from the Market Participants, and include these in the next version of the HAN Guide Please send your feedbacks and comments to: joselito@us.ibm.com (Joselito Samoy)
