Data Structures
class	esphome::Component
class	esphome::PollingComponent
	This class simplifies creating components that periodically check a state. More...
class	esphome::WarnIfComponentBlockingGuard

Namespaces
namespace	esphome
	Providing packet encoding functions for exchanging data with a remote host.
namespace	esphome::setup_priority
	Default setup priorities for components of different types.

Enumerations
enum class	esphome::InternalSchedulerID : uint32_t { esphome::POLLING_UPDATE = 0 , esphome::DELAY_ACTION = 1 }
	Type-safe scheduler IDs for core base classes. More...
enum class	esphome::RetryResult { esphome::DONE , esphome::RETRY }

Functions

void	esphome::clear_setup_priority_overrides ()

Variables
constexpr float	esphome::setup_priority::BUS = 1000.0f
	For communication buses like i2c/spi.
constexpr float	esphome::setup_priority::IO = 900.0f
	For components that represent GPIO pins like PCF8573.
constexpr float	esphome::setup_priority::HARDWARE = 800.0f
	For components that deal with hardware and are very important like GPIO switch.
constexpr float	esphome::setup_priority::DATA = 600.0f
	For components that import data from directly connected sensors like DHT.
constexpr float	esphome::setup_priority::PROCESSOR = 400.0f
	For components that use data from sensors like displays.

constexpr float	esphome::setup_priority::ETHERNET = 250.0f
constexpr float	esphome::setup_priority::BEFORE_CONNECTION = 220.0f
	For components that should be initialized after WiFi and before API is connected.
constexpr float	esphome::setup_priority::AFTER_WIFI = 200.0f
	For components that should be initialized after WiFi is connected.
constexpr float	esphome::setup_priority::AFTER_CONNECTION = 100.0f
	For components that should be initialized after a data connection (API/MQTT) is connected.
constexpr float	esphome::setup_priority::LATE = -100.0f
	For components that should be initialized at the very end of the setup process.
