  // 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.

 | 
						|
    // 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.
