Final answer:
To design and program systems with more than 100 devices, you would need multiple main repeaters. Hybrid keypads and auxiliary repeaters may also be necessary depending on the setup. The Lutron Connect app is not necessary for this purpose.
Step-by-step explanation:
If you want to design and program systems with more than 100 total devices, you would need multiple main repeaters. A main repeater is a device that receives and transmits signals and is essential for expanding the coverage of a system. By using multiple main repeaters, you can increase the capacity and range of the system, allowing it to handle more devices.
Both hybrid keypads and auxiliary repeaters may also be necessary depending on the specific requirements of the system. Hybrid keypads combine both wired and wireless communication and can be helpful in complex setups. Auxiliary repeaters help extend the range of the system.
The Lutron Connect app is a software application that allows you to control and manage your smart home devices. While it can be useful for programming and managing systems, it is not a necessary component for designing and programming systems with more than 100 devices.
