/**
 * @supla-example
 * @file RollerShutter_595_166_io.ino
 * @brief Example of controlling a roller shutter with 74HC595 (outputs) and 74HC166 (inputs) shift registers on an ESP8266/ESP32 for SUPLA integration.
 * This example demonstrates an advanced setup for controlling a roller shutter. It utilizes 74HC595 shift registers
 * to expand output capabilities for motor control (via relays) and status LEDs, and 74HC166 shift registers
 * for reading multiple button inputs (open, close). The system is integrated with the SUPLA cloud
 * via Wi-Fi and includes a web server for configuration.
 * Network settings are configured via the web interface.
 * Users need to adjust GPIO pins for the shift registers, buttons, and relays in the code.
 * A status LED is also configured.
