With the Homematic switch measuring actuator for flush-mounted boxes, even standby consumers can be measured precisely thanks to the high measurement accuracy. The compact design enables easy installation in flush-mounted boxes or in surface-mounted distribution boxes. This enables convenient control via the Homematic IP app or the Homematic IP remote control. The switching and measuring actuator can be operated with the access point in conjunction with the Homematic IP app, the Homematic central unit CCU2 and with many partner solutions.
