The DuoFern plug-in switch is a radio-enabled switching actuator for controlling lights and electrical devices. It allows any devices up to a maximum of 1800 W to be switched wirelessly. The plug has a compact design and is unobtrusive with a diameter of 4 cm. When combined with Rademacher Smart Home central units (HomePilot and Bridge), the socket actuator can be easily controlled via an app or with a Rademacher remote control. Additionally, the actuator can also be operated via voice assistants through the HomePilot and Bridge. With the HomePilot Smart Home, extensive automation features such as standard, weekly, and daily programs, a random function, and an astronomical function are possible. The plug can also be operated locally via a button. The actuator includes many practical additional features such as the stairwell function (turning off after a definable time) and mode switching (switching between light and device mode) and can be easily set up using plug & play – just plug it in, register it, and get started.
