MP202 Enduring Solution for SMETS1 and SMETS2+ PPMIDs

The Smart Energy Code (SEC) currently differentiates between Smart Metering Equipment Technical Specifications (SMETS) 1 and SMETS2+ Devices and is drafted in a manner so that a Device can be either SMETS1 or SMETS2+, but not both. Therefore, the DCC Systems are designed on the premise that the Devices are exclusively either SMETS1 or SMETS2+ Devices. The DCC has several Users who have indicated they would like to use the same Pre-Payment Interface Device (PPMID) for both SMETS1 and SMETS2+ purposes.

The Proposed Solution involves having two rows of the same firmware version for a Device Model included in the CPL: one row for SMETS1 and the other for SMETS2. Devices can be pre-notified as a SMETS1 or SMETS2+, but the Data Service Provider (DSP) will use the SMETS version of the Communications Hub (CH) from the relevant Smart Metering System (SMS) to determine which version of SMETS the system is and update the SMI accordingly.
