// HomeSpan: A HomeKit implementation for the ESP32 //
// ------------------------------------------------ //
// //
// Example 16: Stateless Programmable Switches //
// //
////////////////////////////////////////////////////////////

#include "DEV_ProgButton.h"
#include "DEV_Identify.h"
void setup() {
// Example 16 does not introduce any new HomeSpan functionality, but instead showcases a unique feature of HomeKit that you can readily access with HomeSpan.
// In all prior examples we used the ESP32 to control a local appliance - something connected directly to the ESP32 device. We've then seen how you can control
// the device via HomeKit's iOS or MacOS Home App, or by the addition of local pushbuttons connected directly to the ESP32 device.
// In this example we do the opposite, and use buttons on the ESP32 to control OTHER HomeKit devices.
// To do so, we use HomeKit's Stateless Programmable Switch Service. Similar to other read-only Services, such as the Temperature and Air Quality Sensors
// fully explored in Example 12, the Stateless Programmable Switch Service only listens for event notifications coming from HomeSpan and does not try to control
// or update anything on the HomeSpan Device. More specifically, the Stateless Programmable Switch Service listens for notifications of a SINGLE, DOUBLE,
// or LONG button press coming from HomeSpan.
// What these button presses mean is outside the control of HomeSpan. Instead, you program their actions directly in the Home App. In this fashion, HomeSpan
// becomes a platform for generic buttons that you can program to control any other HomeKit accessory or even trigger HomeKit scenes.
// Upon running this configuration and pairing to HomeKit, your Home App should reveal a new tile labeled "PushButton Switches." Clicking that tile will open up
// a new page where you can program the actions of each of the buttons. These actions can be changed at any time without any need to modify the HomeSpan code,
// or even reboot the device.
// The code for this is quite simple, and as usual we've encapsulated all the functionality in a standalone file: DEV_ProgButton.h. Below we create two generic
// buttons, one connected to pin 23, and one connected to pin 5. See DEV_ProgButton.h for complete details.

// We've written DEV_ProgButton to take two arguments. The first is a pin number that DEV_ProgButton.h uses to create a SpanButton. The second is an index number
// that HomeKit uses as a label when you program the actions of each button in the Home App. The numbers do not have to be sequential, nor start with 1. They just need
// to be unique so HomeKit can distinguish them. Note that HomeKit does not require index numbers if you only have one Stateless Programmable Switch Service within any
// given Accessory. Since we have two, we must specify two unique index numbers.
