On 1 June 2022, the Proposer decided to withdraw this modification due to the Working Group and the SSC concluding that the proposed solution would not be viable due to its security implications.
What is the issue?
SMETS1 meters use the GB mobile telephone networks for their Wide Area Network (WAN) connections. SMETS2 meters are not yet deployed in significant numbers, but those in two out of three Communications Service Provider (CSP) regions will also use GB mobile telephone networks for WAN connections. Thus, WAN performance in SMETS1 deployment gives the best current indication of the likely SMETS2 WAN performance in two out of three CSP regions. Utilita have found over 9% of their SMETS1 meters continue to have poor WAN coverage following install. This means that the meter has WAN intermittently and the WAN connection, to material number of premises, is not sufficient quality to deliver configuration Commands in a sufficiently timely manner.
What is the solution?
This modification seeks to remove the 60 minute time-limit that Communications Hubs (CHs) currently have to allow the Hand Held Terminal (HHT) to join the Home Area Network (HAN) after power-on. This is to give Suppliers the option of providing Prepayment Meter Interface Devices (PPMIDs) to their customers so they can join the HAN without requiring a reliable Wide Area Network (WAN) connection or engineer intervention.
