SECMP0007 Firmware updates to IHDs and PPMIDs

Proposer Mark Pitchford
Lead Analyst Joe Hehir
Date raised 01/03/2016
StageRefinement Process
Implementation date Proposed for November 2020 SEC Release
Latest update The DCC have provided an updated Preliminary Assessment which includes an assessment of two solutions for consideration. This assessment as well as the appropriate next steps were discussed at the May Working Group meeting. This modification is now undergoing a Refinement Consultation which seeks to assess the impacts of the proposed solution, with responses due by Monday 17 June 2019.

What is the issue?

The Proposer of this modification seeks to address the issue of the lack of capability to update firmware Over-The-Air (OTA) for mandated Home Area Network (HAN) Devices via the Data Communications Company’s (DCC’s) infrastructure. The Smart Metering Implementation Programme (SMIP) technical specifications currently capture OTA firmware updates via the DCC to the Communications Hub, Electricity Smart Metering Equipment (ESME) and Gas Smart Metering Equipment (GSME) only. Requirements for OTA firmware updates to mandated HAN devices are not captured.

What is the solution?

Partly due to the high costs as well as the complexity of the proposed solution, the Working Group agreed that in order to progress the modification, they would seek a combination of the two solutions given in the DCC Preliminary Assessment. The DCC suggested the requirements in Option 1 could be constrained to PPMIDs in order to explore cost savings, and that IHDs could be left out of the solution. The Working Group believed that the vast majority of IHDs in the field today were actually PPMIDs with IHD capability.

As a result, the Working Group agreed to progress with a combination of the two solutions:
1. Updating firmware over-the-air (OTA) for PPMIDs via Zigbee (Option 1)
2. Updating firmware OTA for HCALCS via GBCS Critical Commands (Option 2)
