Actuator and energy management system with such actuators

The actuator (12a,12b,12c) comprises a load detecting device (22) for detecting the load of a consumer load (10a,10b,10c,10d) measurement. A communication interface (16) is provided for receiving a manipulated variable. The communication interface is also provided for sending the measured variable which is detected by the load detecting device. An independent claim is also included for the energy management system, particularly home automation system with multiple consumer loads.
