The assignment is to develop/design an OO API that allows you to do the following:

• Create a smart device instance

• Add/remove/update delete the smart device in a group of devices

• Move devices between groups

• Turn on/off a device

• Show the state of all devices

• Set a timer for a device with a simple trigger (on/off), i.e. turn off device 30 minutes after it was turned on.

• Set a schedule for a device (on/off), i.e. turn on a device at 12:30.

• Here are the devices you will support:

• Smart light bulbs with on/off switch, dimming, and (optional) color capabilities

• Smart outlets and/or switches with up to 7 individually-controllable outlets (TP-Link sells these in 1, 2, and power strip versions).

• Other smart devices (doorbells) that can trigger events.
