                      Model Details

                      • Start with a simple model--input/output
                      • To avoid emergencies, set a default buffer (20%?)--amount extra to save
                      • Need to find a balance in the amount of detail to show to users by default
                      • Need to find a balance between letting the program make decisions and letting the users make decisions
                      • Tasks:
                        • Monitor energy consumption of each device, and aggregate consumption
                          • Allow custom grouping of devices
                          • Make sure naming distinguishes devices, in the case that there are multiple devices of the same type
                          • Hierarchical structure of grouping allows scalability
                          • Be able to sort by consumption over a certain period of time
                        • Control devices
                          • Turn on and off
                          • Change settings
                          • Control remotely, not necessarily from the same network
