The Home Assistant core is responsible for Home Control. Home Assistant has four parts to make this possible:
|
||||
|
||||
* The **Event Bus** facilitates the firing and listening of events. This is the beating heart of Home Assistant.
|
||||
* The **State Machine** keeps track of the states of things. It fires a `state_changed` event when a state has been changed.
|
||||
* The **Service Registry** listens on the event bus for `call_service` events and allows other code to register services.
|
||||
* The **Timer** will send a `time_changed` event every 1 second on the event bus.
