With the Rademacher App, your integrated DuoFern devices can be conveniently controlled via smartphone or tablet - from home or on the go. The app offers you quick and easy access to your devices and scenes. What position are the shutters in? What temperature is set on the heating thermostat? Is the light still on in the bedroom? You can keep track of things with a quick look at the app. Your home will also keep you up to date with push notifications! You can arrange your favorite devices of the Rademacher SmartHome system clearly in the dashboard - the start page of the app - and have the most important information at a glance. This also applies to sensor data such as temperature, sun direction and wind speed, or activated and deactivated automations and status messages. In addition, the app offers user-friendly and intuitive operating elements, for example a thermostat rotary control or the roller shutter control element, which can be moved from top to bottom like the curtain. It is also possible to carry out the complete configuration of the central unit. You can use this to register all devices, set up automations, create individual scenes and make system settings. Another special feature of ours: "Triggers" can be created separately from a scene. If a previously defined trigger occurs - for example, if the temperature reaches a certain level or if the environmental sensor should respond to rain - it either activates an associated scene or just sends a push message for information without triggering an action.
