TR-5 Adopted
The BMWK has finalized BSI TR-03109-5. TR-5 ensures interoperability for users (end customers/operators) of the SMGW at the CLS interface with other components that control downstream heat pumps, wallboxes, or battery storage systems. It also describes security requirements for applications within the SMGW’s home area network (HAN) as part of the implementation of Section 14a of the Energy Industry Act (EnWG).
