The name of the resource.

Methods

doCommand

doCommand(command: Struct | Record<string, JsonValue>): Promise<JsonValue>
Send/Receive arbitrary commands to the resource.
Parameters
- command: Struct | Record<string, JsonValue>
  The command to execute. Accepts either a Struct or a plain object, which will be converted automatically.
Returns Promise<JsonValue>
Example
```
// Plain object (recommended)
const result = await resource.doCommand({
  myCommand: { key: 'value' },
});

// Struct (still supported)
import { Struct } from '@viamrobotics/sdk';

const result = await resource.doCommand(
  Struct.fromJson({ myCommand: { key: 'value' } })
);
```
Inherited from Resource.doCommand

getReadings

getReadings(extra?: Struct): Promise<Record<string, JsonValue>>
Return the readings of a sensor.
Parameters
- Optionalextra: Struct
Returns Promise<Record<string, JsonValue>>
Example
```
const sensor = new VIAM.SensorClient(machine, 'my_sensor');

// Get the readings of a sensor.
const readings = await sensor.getReadings();
```
