The history is stored in a SQLite database `home-assistant_v2.db` within your
configuration directory unless the `recorder` integration is set up differently.
- events table is all events except `time_changed` that happened while recorder integration was running.
- states table contains all the `new_state` values of `state_changed` events.
- Inside the states table you have:
- `entity_id`: the entity_id of the entity
- `state`: the state of the entity
- `attributes`: JSON of the state attributes
- `last_changed`: timestamp last time the state has changed. A state_changed event can happen when just attributes change.
- `last_updated`: timestamp anything has changed (state, attributes)
- `created`: timestamp this entry was inserted into the database

When the `history` integration queries the states table it only selects states
where the state has changed: `WHERE last_changed=last_updated`
