## SmartDeviceModel.publishDps

> [VERSION] @ray-js/panel-sdk >= 1.6.0

> 💡 For enum, valid values are the literal union defined by property.range (e.g., 'white' \| 'colour').
> For value, valid values must be within property.min/max (auto-clamped).

### Description

Control multiple smart device DPs in batch, built on top of ty.device.publishDps

### Parameters

`Params`

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `data` | `Record<string, DpValue>` | Yes | Key-value pairs of DPs to publish. Keys are DP codes; value types must be derived from the device’s DP schema: bool → boolean, value → number, enum → property.range literal union, bitmap → number, string/raw → string |
| `options` | `SendDpOption` | No | Publish options. deviceId and dps are no longer required parameters. SendDpOption is an advanced configuration provided by dp-kit interceptors |

### Return Value

Type: `Promise<boolean>`

Whether the publish was successful

### Referenced Types

##### `type` DpValue

Datapoint value type, which can be boolean, number, or string.

```typescript
export type DpValue = boolean | number | string;
```

##### `type` SendDpOption

DP send options. Can be used as the global default configuration for createDpKit, and can also be overridden in a single publishDps/action call.
The global `sendDpOption` suits product-level defaults;
options passed for a single send are suitable for temporarily overriding throttling, debouncing, protocol parsing, or optimistic update strategies.
Note: requires the dp-kit interceptor.

| Property | Type | Since | Description |
| --- | --- | --- | --- |
| `immediate` | `boolean` | - | Whether to trigger a state update immediately; requires the dp-kit interceptor |
| `ignoreDpDataResponse` | `boolean \| IgnoreDpChangeInterceptorOptions` | `1.11.0` | Whether to ignore DP reports; default false |
| `synchronizeDevProperty` | `boolean \| DevPropInterceptorOptions` | `1.11.0` | Whether to sync dpData with cloud device properties; default false |
| `ordered` | `boolean` | - | Whether to send multiple DPs in the order of the object’s keys; requires the dp-kit interceptor; default false |
| `checkRepeat` | `boolean` | - | Whether to check for duplicate values and skip sending; requires the dp-kit interceptor; default false Compared with the current `dpState`; duplicates are detected and not sent |
| `delay` | `number` | - | Delayed send; requires the dp-kit interceptor; default 0, in ms |
| `throttle` | `number` | - | Send throttling (conflicts with debounce); requires the dp-kit interceptor; default 0, in ms |
| `debounce` | `number` | - | Send debounce (conflicts with throttle); requires the dp-kit interceptor; default 0, in ms |
| `protocols` | `Record<string, CustomRawDpMap>` | - | A per-call DP protocol converter; requires the dp-kit interceptor. The key is the dpCode and the value is a `{ parser, formatter }` object: - parser(dpValue: string) => any — parses the raw DP string into a structured object - formatter(parsedValue: any) => string — serializes the structured object into a DP string Affects only this invocation and does not override the global protocols configuration in createDpKit |

##### `type` IgnoreDpChangeInterceptorOptions

Configuration option to ignore the DP data change interceptor

Used to configure the debounce mechanism for DP reporting events on the device panel, preventing immediate responses after panel operations from affecting user experience or business logic

| Property | Type | Description |
| --- | --- | --- |
| `whiteDpCodes` | `string[]` | DP whitelist; reports will not be ignored |
| `timeout` | `number` | Debounce timeout check, in milliseconds, default 5000 - The maximum time between sending a DP from the panel and receiving the DP reply; dpDataChange is triggered only if this is exceeded. - Used to debounce DP reporting events |
| `customRule` | `(dpState: DpState, lastSendTimestamp: number) => boolean` | Custom ignore rules > Highest priority; when configured, whiteDpCodes and timeout become ineffective |

##### `type` DevPropInterceptorOptions

| Property | Type | Description |
| --- | --- | --- |
| `blackDpCodes` | `string[]` | DP blacklist; will not be synchronized to the cloud |
| `defaultState` | `DpState` | Default device state on first entry; supports async initialization |
| `throttle` | `number` | Send throttling, in milliseconds, defaults to 0 If set to 0, throttling is disabled. |

##### `type` DpState

Datapoint status object, where the key is the datapoint code and the value is the datapoint value.

```typescript
export type DpState = Record<string, DpValue>;
```

##### `type` CustomRawDpMap

Custom DP protocol converter for transforming between raw DP strings and structured objects.
Suitable for composite DPs of type raw/string (e.g., a light's colour_data "00ff003e8"),
splitting a single string into multiple semantic fields (e.g., { hue, saturation, value }).

| Property | Type | Description |
| --- | --- | --- |
| `parser` | `(dpValue: string) => any` | Parse the raw DP string reported by the device into a structured object |
| `formatter` | `(parsedDpValue: any) => string` | Serialize the structured object into a DP string to be sent to the device |

##### `interface` DpSchema

| Property | Type | Description |
| --- | --- | --- |
| `attr` | `number` | DP attribute flag bit, used to mark additional capabilities of the DP |
| `canTrigger` | `boolean` | Whether it can be used as an automation trigger condition |
| `code` | `string` | DP code, e.g., switch |
| `defaultRecommend` | `boolean` | Whether it is the default recommended DP |
| `editPermission` | `boolean` | Whether it has edit permission |
| `executable` | `boolean` | Whether it can be issued (sent downstream) |
| `extContent` | `string` | DP extension content, typically a JSON string |
| `iconname` | `string` | DP icon name |
| `id` | `string \| number` | DP ID |
| `mode` | `"rw" \| "ro" \| "wr"` | DP mode type rw: writable and reportable (read/write) ro: report-only (read-only) wr: write-only |
| `name` | `string` | DP name, typically used in voice scenarios |
| `property` | `Object` | DP attributes |
| `type` | `"raw" \| "obj"` | DP data type categories: raw for raw byte stream, obj for structured object |

##### `type` DpSchema.property

| Property | Type | Description |
| --- | --- | --- |
| `type` | `"string" \| "bool" \| "value" \| "enum" \| "bitmap" \| "raw"` | DP type |
| `range` | `string[] \| string[]` | Enum value range; present only when type = enum |
| `label` | `string[] \| string[]` | Fault label list; present only when type = bitmap |
| `maxlen` | `number` | Maximum length for fault bitmap; present only when type = bitmap |
| `unit` | `string` | Unit (type = value only) |
| `min` | `number` | Minimum value (type = value only) |
| `max` | `number` | Maximum value (type = value only) |
| `scale` | `number` | Precision (type = value only) |
| `step` | `number` | Step (type = value only) |


### Examples

#### Basic command sending.

```typescript
// Constrain input params based on the device DP schema
await device.publishDps({ switch_led: true });               // boolean
await device.publishDps({ work_mode: 'colour' });            // 'white' | 'colour' (IDE auto-completion)
await device.publishDps({ brightness: 500 });                // number (clamped to 10~1000 at runtime)
await device.publishDps({ switch_led: true, brightness: 800 }); // Supports batch publishing
```

#### Advanced dp-kit interceptor configuration (requires use with createDpKit).

```typescript
// Immediately update local state (optimistic update, without waiting for device report)
await device.publishDps({ brightness: 800 }, { immediate: true });

// Throttle 300ms, suitable for high-frequency interactions like sliders
await device.publishDps({ brightness: 800 }, { throttle: 300 });

// Debounce 500ms, send only after user stops interacting
await device.publishDps({ brightness: 800 }, { debounce: 500 });

// Do not send duplicate values to avoid redundant commands
await device.publishDps({ switch_led: true }, { checkRepeat: true });

// Ignore the device report after this publish (prevent slider bounce-back)
await device.publishDps({ brightness: 800 }, { ignoreDpDataResponse: true });

// Combine options
await device.publishDps(
  { brightness: 800 },
  { immediate: true, throttle: 300, ignoreDpDataResponse: true },
);
```
