MP155 Communications Hub Re-Flash

Proposer Tom Rothery

Date raised 18/02/2021
StageWithdrawn
Implementation date N/A
Latest update Following feedback from the Refinement Consultation Responses and the October 2022 Working Group, there is no demand for the service as outlined in the DCC Preliminary Assessment and no support for continuing to the Impact Assessment stage. The Proposer considers that withdrawing it now is the most economic and efficient course of action for all concerned. The Proposer notified SECAS on 06 October 2022 of their intention to withdraw this modification. This modification has now been withdrawn.

What is the issue?

Currently, the Smart Energy Code (SEC) allows for the return of Communications Hubs (CHs) in accordance with SEC Section F ‘Smart Metering System Requirements’ (F8) and Appendix I ‘CH Installation and Maintenance Support Materials’. However, the SEC does not currently accommodate the process of returning a Communications Hub to the DCC for the purpose of re-flashing the Device and then retaking delivery of that Device once the re-flashing process has been complete. Furthermore, there is not an Explicit Charge that could be used for this service.

Installing older versions of Communications Hubs presents issues for Suppliers. This is due to the over-the-air (OTA) upgrade which, when run at installation, can take a significant amount of time and increases the length of installation.

What is the solution?

The DCC will implement a process to manage requests from SEC Parties to re-flash Communications Hubs.
The relevant CSP will update each Communications Hub that is returned to it for re-flashing to the latest production Firmware Version for that Device Model and redeliver it to the SEC Party that requested the service.
On receipt of the notification from the CSP, the DSP will update the Smart Metering Inventory (SMI) with the new information received, including any updates to the Firmware Version.
