// HomeSpan: A HomeKit implementation for the ESP32 //
// ------------------------------------------------ //
// //
// Example 1: A non-functioning on/off light control //
// constructed from basic HomeSpan components //
// //
////////////////////////////////////////////////////////////
// WELCOME TO HOMESPAN!
// This first example introduces the HomeSpan library and demonstrates how to implement a simple on/off light control
// using a combination of HomeSpan Accessory, Service, and Characteristic objects. Once this sketch has been uploaded
// to your HomeSpan device and the device is paired to your home, a new "lightbulb" tile will appear in the Home App of your iPhone,
// iPad, or Mac.
// Though the tile will be fully operational (i.e. you can change the status of the lightbulb from "on" or "off"), we won't yet connect
// an actual light or LED to the HomeSpan device, so nothing real will light up. Instead, in this and the next few examples, we'll focus
// on learning about the different ways HomeKit controls can be configured. Starting in Example 5, we'll connect an LED to the device
// and introduce the methods that actually turn the LED on and off from your Home App.
// NOTE: All HomeSpan examples are best understood when reviewed in conjunction with the documentation provided on the HomeSpan GitHub page.
// See https://github.com/HomeSpan/HomeSpan for details and references. In particular, you may want to review the HomeSpan API Overview
// page before proceeding.
// These examples also make frequent reference to Apple's HomeKit Accessory Protocol Specification, known as HAP. You can download this
// directly from Apple at https://developer.apple.com/support/homekit-accessory-protocol.
// LET'S GET STARTED...
#include "HomeSpan.h" // HomeSpan sketches always begin by including the HomeSpan library
void setup() { // Your HomeSpan code should be placed within the standard Arduino setup() function
Serial.begin(115200); // Start a serial connection so you can receive HomeSpan diagnostics and control the device using HomeSpan's Command-Line Interface (CLI)
// The HomeSpan library creates a global object named "homeSpan" that encapsulates all HomeSpan functionality.
// The begin() method is used to initialize HomeSpan and start all HomeSpan processes.
// The first two parameters are Category and Name, which are used by HomeKit to configure the icon and name of the device shown in your Home App
// when initially pairing your device.
homeSpan.begin(Category::Lighting,"HomeSpan LightBulb"); // initializes a HomeSpan device named "HomeSpan Lightbulb" with Category set to Lighting
// Next, we construct a simple HAP Accessory Database with a single Accessory containing 3 Services,
// each with their own required Characteristics.
new SpanAccessory(); // Begin by creating a new Accessory using SpanAccessory(), which takes no arguments
new Service::AccessoryInformation(); // HAP requires every Accessory to implement an AccessoryInformation Service, which has 6 required Characteristics:
new Characteristic::Name("My Table Lamp"); // Name of the Accessory, which shows up on the HomeKit "tiles", and should be unique across Accessories
// The next 4 Characteristics serve no function except for being displayed in HomeKit's setting panel for each Accessory. They are nevertheless required by HAP:
new Characteristic::Manufacturer("HomeSpan"); // Manufacturer of the Accessory (arbitrary text string, and can be the same for every Accessory)
new Characteristic::SerialNumber("123-ABC"); // Serial Number of the Accessory (arbitrary text string, and can be the same for every Accessory)
new Characteristic::Model("120-Volt Lamp"); // Model of the Accessory (arbitrary text string, and can be the same for every Accessory)
new Characteristic::FirmwareRevision("0.9"); // Firmware of the Accessory (arbitrary text string, and can be the same for every Accessory)
// The last required Characteristic for the Accessory Information Service is the special Identify Characteristic. We'll learn more about this
// Characteristic in later examples. For now, you can just instantiate it without any arguments.
new Characteristic::Identify(); // Create the required Identify
// *NOTE* HAP requires that the AccessoryInformation Service always be instantiated BEFORE any other Services, which is why we created it first.
// HAP also requires every Accessory (with the exception of those in Bridges, as we will see later) to implement the HAP Protocol Information Service.
// This Service supports a single required Characteristic that defines the version number of HAP used by the device.
// HAP Release R2 requires this version to be set to "1.1.0"
new Service::HAPProtocolInformation(); // Create the HAP Protcol Information Service
new Characteristic::Version("1.1.0"); // Set the Version Characteristicto "1.1.0" as required by HAP
// Now that the required "informational" Services have been defined, we can finally create our Light Bulb Service
new Service::LightBulb(); // Create the Light Bulb Service
new Characteristic::On(); // This Service requires the "On" Characterstic to turn the light on and off
// That's all that's needed to define a database from scratch, including all required HAP elements, to control a single lightbulb.
// Of course this sketch does not yet contain any code to implement the actual operation of the light - there is nothing to
// turn on and off. But you'll still see a Light Bulb tile show up in your Home App with an ability to toggle it on and off.
} // end of setup()
//////////////////////////////////////
void loop(){
// The code in setup above implements the Accessory Attribute Database, but performs no operations. HomeSpan itself must be
// continuously polled to look for requests from Controllers, such as the Home App on your iPhone. The poll() method below is all that
// is needed to perform this continuously in each iteration of loop()
homeSpan.poll(); // run HomeSpan!
} // end of loop()
// Congratulations! You've created your first HomeSpan sketch, ready to be uploaded to your ESP32 board and paired with HomeKit.
