## Data and privacy

Feed: `screenrig.tides/v1`.

Feed documents carry source attribution. The Player supplies the feed to the card.

## Properties

For theme, background, accent and position, see [Common properties](/docs/cards/#common-properties).

Set static properties in `params`. Bind `data` to a project card data key for live values; that document holds only dynamic properties. Without a data key, put the complete configuration in `params`. Nested rows describe the contents of their parent property.

### Static properties

| Name | Type | Default | Values and limits | Description |
| --- | --- | --- | --- | --- |
| `units` | string | `"auto"` | `"auto"`, `"m"`, `"ft"` | Heights in metres or feet. auto uses the feed's own units. |
| `hour12` | boolean | `false` |  |  |
| `timeZone` | string, null | `null` |  | IANA zone for the day shown; null uses the screen's zone. |

### Dynamic properties

This card has no dynamic properties.
