Home View

The Home view is where the SnapVue user will spend the majority of their time. It has a navigation bar at the top and one or more tiles representing the available actions. The tiles that are displayed depend on the context, the zone in which the user is detected and his/her profile. This is configured on the PcVueWeb & Mobile back end server. Tapping a tile executes the action associated with it. Some tiles display information, for example a Trend view, others perform actions such as sending a command on a variable or an alarm.
