Scenario

You are the IT manager of a company that makes in$-$home smart thermostats. Before you develop any code or build any product, you will need to create a system design that can be reviewed by your IT departments and key users.

This requires you to establish a design that is both functional and easy to use. You have decided to use a class$-$based design for the product, and so all subsequent design decisions flow from this. After developing the class$-$based design, you will establish the technical flow diagrams $($data flow, state chart, etc.$).$ These should be clear and understandable to the IT staff.

Once the flowcharts are constructed, you can continue with a user interface design, always thinking from the users' point of view. You may think you know what a user wants, but many companies also bring in end$-$users to provide feedback on your design.

Finally, you'll need to justify your design and decisions to upper management before you can move forward.

Here is what you'll need to complete for this assignment:

Data flow diagram

my data flow diagram needs to include additional entities required for the smart thermostat system $($e$.$g$.$ app, server, thermostat controller, and HVAC$).$

my data flow diagram needs to include more processes and data flows associated with additional thermostat features $($e$.$g$.$ change schedules, change modes, change thermostat settings, turn on$/$off thermostat$).$

A data flow diagram needs to include at least one data store.

based on these suggesstions please provide me with a new data flow diagram and its associated state chart and activity diagram
