Read full description

Diese App dient als benutzerfreundliche Schnittstelle zur Steuerung Ihres Home Assistants und der darin eingerichteten Szenen und Geräte. Mit dieser App können Sie ganz einfach Szenen oder einzelne Geräte aktivieren. Die App bietet zudem die Möglichkeit, Szenen mit Bildern und hilfreichen Anleitungen zu verknüpfen. Auf diese Weise erhalten die Benutzer, wenn sie beispielsweise auf die Szene "Besprechung" klicken, visuelle Anweisungen, um alles korrekt einzurichten. Im Admin-Modus können Sie die Schlüssel für das Aktivieren und Deaktivieren von Szenen hinzufügen. Diese Schlüssel sind im Grunde genommen zwei vorher im Home Assistant eingerichtete Szenen. Die App dient als Auslöser für diese Szenen und macht die Steuerung somit einfacher und intuitiver.
