You've successfully created a prototype based on your work in Case Project 13-2. You want to create six of these controllers for different windows in the home. You want to be able to control them and check their status from a centrally located wall-mounted display that communicates with all the controllers. You plan to add more home automation IoT devices throughout the house and you want to control and check their status with the central display. What hardware do you recommend for the wall-mounted central display that communicates with all the controllers? What features should the hardware include?
