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.

Welcome to "When Was It?" – the app that's more about the "Did-Do" than the "To-Do"! In a world full of reminders telling you what you're about to do, "When Was It?" is your personal time-travel agent that keeps tabs on what you've already done. Whether it's the vitamin you popped, the dog you walked, or that spontaneous moonwalk in the kitchen – if you did it, we log it. Categorize your actions with emojis that even your grandma could understand. And let's talk about Siri – your voice-activated memoirist. Say "Siri, I just meditated," and boom – it's logged with a timestamp precise enough to make a Swiss watch blush. Ask "When did I last meditate?" and Siri's on it faster than you can say "Ommm." So go ahead, live your life and let "When Was It?" handle the history. Because every action deserves its own spotlight, and we make sure it gets one – with a cherry on top.
