### `distinct`

The distinct filter passes through a new text value only when it changes.
If the incoming string is identical to the previously emitted one, it is suppressed.
This is useful to avoid unnecessary updates or MQTT traffic when the text sensor’s value stays the same.

```yaml
filters:
- distinct:
```
