In April 2020, DCC issued a consultation on changes to the SMETS1 Transition and Migration Approach Document (TMAD) covering:
- an approach to the security testing of SMETS1 Devices; and
- changes to the notification period for the upgrade of firmware / application of configuration as well as prior notice for Migration for SMETS1 Installations containing Dormant Devices.
On 4 June 2020, DCC concluded on the consultation and provided the documentation to BEIS.
