HomeSpan Services and Characteristics
HomeSpan implements all HAP-R2 Services and Characteristics except for those that involve video or audio streaming, Apple TV, or advanced lock management (i.e. all HAP Services except those that require Characteristics with a TLV8 data type).
HomeSpan Services and Characteristics are implemented as C++ Classes with names that exactly match the spelling and capitalization specified by Apple in Sections 8 and 9 of HAP-R2, but without any spaces. HomeSpan Services are defined in HomeSpan's Service namespace. HomeSpan Characteristics are defined in HomeSpan's Characteristic namespace. For example, Carbon Dioxide Sensor (HAP Service 8.7) and Carbon Dioxide Detected (HAP Characteristic 9.16) are respectively defined in HomeSpan as Service::CarbonDioxideSensor and Characteristic::CarbonDioxideDetected.
HomeSpan Services and Characteristics are instantiated with a C++ new command. Services do not take any arguments, whereas Characteristics take a single, optional argument that is used to initialize the value of the Characteristic at startup. If this argument is not specified, HomeSpan will apply a reasonable default value based on the Characteristic's type and allowed range.
A list of all HomeSpan Services is provided in the table below. For each Service the table also indicates which Characteritics are required and which are optional. For example, a HomeSpan light bulb could be configured as such:
new Service::LightBulb(); // instantiates a Light Bulb Service
new Characteristics:On(); // instantiate the required On Characteristic without setting initial value
new Characteristic::Brightness(50); // instantiate an optional Brightness Characteristic and set initial value to 50%
new Characteristic::Name("Living Room Lamp"); // instantiate an optional Name Characteristic for this Service, and set to "Living Room Lamp"
Upon startup HomeSpan will validate the device configuration to ensure any Service you instantiate includes every required Characteristics, and does include aany Charcteristic that is neither required nor optional. If any errors are found at startup HomeSpan reports them to the Arduino Serial Monitor and halts the program
