The screen displayed above is the main screen of the application. It gives the user easy access to most of the features the application has to offer.
The user can view different types of graphs by clicking the tabs below the graph display. For energy consuming devices, the user can view a graph displaying the cost (money spent), consumption, pricing information or a combination of all three (each displayed in a different color). The view options for energy generating devices, such as solar panels, are slightly different, allowing the user to view a graph displaying generated power.
The application enables the user to view usage or consumption information for different devices. The user can select a specific device for which to view consumption, or usage data by selecting the device (or appliance) in the devices list at the top of the screen. The application also enables the user to view the total consumption for all the devices by selecting the All option (for more information, see the Storyboard). The user can edit the settings of the selected appliance by clicking the Config Device button. When the All option is selected the Config Device button is disabled, in order to eliminate confusion (since it is impossible to edit the settings for all the appliances together). There are two of appliances, Generators and Consumers (more on that below). For generator devices, the interface enables the user to sell power by displaying an additional button that reads "Sell Power". This button is hidden when a non generator appliance is selected.
The user can change the time frame of the displayed data by clicking the lower set of tabs, which allow the user to view data by day, month or year.
The day view (Day tab) enables the user to view daily data recorded on different dates. The user can view data from a different day by setting the date control (on the top of the screen) to the desired date.
The month view(month tab) enables the user to view monthly data. The user can only change the month and the year (not the day). When the Year tab is selected the user can only change the year and the displayed data includes all the data recorded during the selected year.
