#include "HomeSpan.h"
```
## *homeSpan* (object)
At runtime this HomeSpan will create a global object named `homeSpan` that supports the following methods:
* `void begin(Category catID, char *displayName, char *hostNameBase, char *modelName)`
* Initializes HomeSpan.
* **Must** be called at the beginning of each sketch before any other HomeSpan functions and is typically placed near the top of the Arduino `setup()` method, but **after** `Serial.begin()` so that initialization diagnostics can be output to the Serial Monitor.
* All arguments are **optional**.
* *catID* - the HAP Category HomeSpan broadcasts for pairing to HomeKit. Default is Category::Lighting. See [HomeSpan Accessory Categories](Categories.md) for a complete list.
* *displayName* - the MDNS display name broadcast by HomeSpan. Default is "HomeSpan Server".
* *hostNameBase* - the full MDNS host name is broadcast by HomeSpan as *hostNameBase-DeviceID*.local, where DeviceID is a unique 6-byte code generated automatically by HomeSpan. Default is "HomeSpan".
* *modelName* - the HAP model name HomeSpan broadcasts for pairing to HomeKit. Default is "HomeSpan-ESP32".

The following **optional** `homeSpan` methods override various HomeSpan initialization parameters used in `begin()`, and therefore **should** be called before `begin()` to take effect. If a method is *not* called, HomeSpan uses the default parameter indicated below:
* `void setControlPin(uint8_t pin)`
* Sets the ESP32 pin to use for the HomeSpan Control Button (default=21).
* sets the ESP32 pin to use for the HomeSpan Control Button (default=21)
* `void setStatusPin(uint8_t pin)`
* Sets the ESP32 pin to use for the HomeSpan Status LED (default=LED_BUILTIN).
* sets the ESP32 pin to use for the HomeSpan Status LED (default=LED_BUILTIN)
* `void setApSSID(char *ssid)`
* Sets the SSID (network name) of the HomeSpan Setup Access Point (default="HomeSpan-Setup").
* sets the SSID (network name) of the HomeSpan Setup Access Point (default="HomeSpan-Setup")
* `void setApPassword(char *pwd)`
* Sets the password of the HomeSpan Setup Access Point (default="homespan").
* sets the password of the HomeSpan Setup Access Point (default="homespan")
* `void setApTimeout(uint16_t nSec)`
* Sets the duration (in seconds) that the HomeSpan Setup Access Point, once activated, stays alive before timing out (default=300 seconds).
* sets the duration (in seconds) that the HomeSpan Setup Access Point, once activated, stays alive before timing out (default=300 seconds)
* `void setCommandTimeout(uint16_t nSec)`
* Sets the duration (in seconds) that the HomeSpan End-User Command Mode, once activated, stays alive before timing out (default=120 seconds).
* sets the duration (in seconds) that the HomeSpan End-User Command Mode, once activated, stays alive before timing out (default=120 seconds)
* `void setLogLevel(uint8_t level)`
* Sets the logging level for diagnostic messages, where:
* sets the logging level for diagnostic messages, where:
* 0 = top-level status messages only (default),
* 1 = all status messages, and
* 2 = all status messages plus all HAP communication packets to and from the HomeSpan device.
* This parameter can also be changed at runtime via the [HomeSpan CLI](CLI.md).
* 2 = all status messages plus all HAP communication packets to and from the HomeSpan device
* this parameter can also be changed at runtime via the [HomeSpan CLI](CLI.md)
* `void setMaxConnections(uint8_t nCon)`
* Sets the maximum number of HAP Controllers that be simultaneously connected to HomeSpan (default=8).
* sets the maximum number of HAP Controllers that be simultaneously connected to HomeSpan (default=8)
## Creating the HAP Accessory Attributes Database - Primary Classes
## *SpanAccessory()* (class)
The HAP Accessory Attributes Database is constructed by instantiating (using `new`) a combinaton of the following HomeSpan Classes:
Creating an instance of this class add a new HAP Accessory to the HomeSpan HAP Database.
* every HomeSpan sketch requires at least one Accessory
* there are no arguments or associated methods
* you must call `homeSpan.begin()` before instantiating any Accessories
* example: `new SpanAccessory();`
## *SpanService()* (base class)
This is a **base class** from which all HomeSpan Services are derived. To create a new Service, instantiate one of HomeSpan Services defined in the Service namespace
* `SpanAccessory()`
* This creates a new HAP Accessory to hold HAP Services.
* There are no arguments or methods.
* You must call `homeSpan.begin()` before instantiating any Accessories.
* Every HomeSpan sketch requires at least one Accessory.
* `SpanService()`
* This is the base class for creating new HAP Services. It should
