<img src='/images/screenshots/logbook.png' style='margin-left:10px; float: right;' height="100" /> The logbook component provides a different perspective on the history of your house by showing all the changes that happened to your house in reverse chronological order. [See the demo for a live example](/demo/).

To enable the logbook in your installation, add the following to your `configuration.yaml` file:

```yaml
# Example configuration.yaml entry
logbook:
```

It is possible to add custom entries to the logbook by using the script component to fire an event.

```yaml
# Example configuration.yaml entry
script:
  add_logbook_entry:
    alias: Add Logbook
    sequence:
      - event: LOGBOOK_ENTRY
        event_data:
          name: Kitchen
          message: is being used
          # Optional
          entity_id: light.kitchen
          domain: light
```
