A short tab on a tile allows you to switch off the light directly, for example. - The ‘Weather’ window shows you the weather data from your free@home weather station. - The ‘Next switching times’ window shows the two functions that will be switched next using the automated time programme. The event can be suspended once using the slider. A tab on the switching times overview displays all switching events for the next 24 hours. - The ‘Favourites’ are a collection of individually selected functions. The selection is made by setting the ‘star’ symbol. The function can be executed directly by clicking on the small blue symbol at the top right of the favourites tile. By tabbing on the main area of the tile, the function is called up in fullscreen view, which offers even more setting options. The order of the function areas can be changed using the ‘Edit’ button at the bottom of the home page. **ROOMS** Here you can access all the devices in your free@home installation. **AUTOMATION** Timer Existing time programmes can be activated/deactivated (and new time programmes can be created in the future).
