Before we dive into the Home Assistant architecture, it is important to get a clear overview of the home automation landscape as a whole. This will allow us to show how the different parts of Home Assistant fit in the picture.

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.
