The in-wall switching measurement actuator FSM allows for convenient switching of connected consumers via radio, while simultaneously capturing, evaluating, and linking energy consumption data from the connected device. Note: This is a kit that needs to be assembled! The actuator can switch resistive loads with a maximum power of 1150 W using the free Homematic IP app or via the CCU3 central unit, and it can also determine the respective consumption. It is possible to evaluate the mains voltage, current, power consumption of the connected load, and the mains frequency. Thanks to its compact design, the switching measurement actuator fits comfortably into standard in-wall or surface-mounted boxes. If the switching measurement actuator is housed in a waterproof surface-mounted box, such as Abox 025 or Abox 040, it can also be used outdoors. The integrated measurement function enables reliable detection of powered consumers, allowing for the monitoring and evaluation of standby consumption of the connected load. Additionally, a week timer program that can be configured in a central unit or the HmIP app can be securely stored in the actuator, which will continue to operate even if there is no connection to the central unit or access point due to radio control. Switching capacity is 5 A/1150 W, with a relay contact. Very low self-consumption, only 0.2 W. Measurement of voltage, current, power, and mains frequency; when connected to a central unit (CCU3), versatile evaluation is possible, for example, through diagrams, and setting reactions to configurable threshold values. Internal, fail-safe storage of a weekly switching program, operating independently of the central unit. Compact design for installation in standard in-wall boxes according to DIN 49073-1 or junction boxes according to DIN.
