The Smart Building Hub provides a wireless, intuitive user interface optimized for mobile use. Screens, such as the Circle of Comfort and Spaces, provide at-a-glance status of a supported device. Menus, such as the Device menu, display critical alarms so that you can select them and act upon them. The Smart Building Hub user interface scales to the device you are using. On a computer screen or tablet, the main menus and screens are side by side. On a phone display, you see either the menu or the screens you selected from that menu.
