In apartments, circuits are usually fused with max. 16A. The digitalSTROM system uses each circuit as the smallest unit. The reasons are:
- Each circuit is an independent communication system. This significantly improves the response time.
- The electrical energy and power of each circuit can thus be measured individually.
- In the event of a failure, only one circuit is affected and not the entire home.
- With only a single dSM for the entire house, these advantages would be eliminated and the system would be considerably slower.
