SECMP0056 IHD / PPMID Zigbee Attributes Available on the HAN

Proposer Emslie Law
Lead Analyst Bradley Baker
Date raised 05/07/2018
StagePending Implementation
Implementation date November 2022 SEC Release
Latest update On 29 April 2021 the Authority determined that SECMP0056 should be approved for implementation. SECMP0056 will be implemented as part of the November 2022 SEC Release.

What is the issue?

Currently under the SEC, SMETS2 Type 1 and Type 2 devices (specifically In-Home Displays (IHDs) and Prepayment Interface Devices (PPMIDs), notwithstanding Consumer Access Devices (CADs)) are not notified of a Change of Tenancy (COT) or Change of Supplier (COS) event. This could allow a new tenant to access the previous tenant’s personal information and place the Supplier in breach of the General Data Protection Regulation (GDPR). The solution proposes to make the appropriate Zigbee attributes available to IHDs/PPMIDs on the Home Area Network (HAN) under SMETS2 as is currently the case in SMETS1.

What is the solution?

The solution proposes to make Zigbee attributes for CoT parameters available to HAN Devices such as IHDs and PPMIDs and also mandate IHDs and PPMIDs to query the ESME and GPF for CoT information.
