Use ListThings with an AWS SDK or CLI

The following code examples show how to use ListThings.

CLI

AWS CLI

Example 1: To list all things in the registry

The following list-things example lists the things (devices) that are defined in the AWS IoT registry for your AWS account.

aws iot list-things

Output:

{
    "things": [
        {
            "thingName": "ThirdBulb",
            "thingTypeName": "LightBulb",
            "thingArn": "arn:aws:iot:us-west-2:123456789012:thing/ThirdBulb",
            "attributes": {
                "model": "123",
                "wattage": "75"
            },
            "version": 2
        },
        {
            "thingName": "MyOtherLightBulb",
            "thingTypeName": "LightBulb",
            "thingArn": "arn:aws:iot:us-west-2:123456789012:thing/MyOtherLightBulb",
            "attributes": {
                "model": "123",
                "wattage": "75"
            },
            "version": 3
        },
        {
            "thingName": "MyLightBulb",
            "thingTypeName": "LightBulb",
            "thingArn": "arn:aws:iot:us-west-2:123456789012:thing/MyLightBulb",
            "attributes": {
                "model": "123",
                "wattage": "75"
            },
            "version": 1
        },
        {
        "thingName": "SampleIoTThing",
        "thingArn": "arn:aws:iot:us-west-2:123456789012:thing/SampleIoTThing",
        "attributes": {},
        "version": 1
        }
    ]
}

Example 2: To list the defined things that have a specific attribute

The following list-things example displays a list of things that have an attribute named wattage.

aws iot list-things \
    --attribute-name wattage

Output:

{
    "things": [
        {
            "thingName": "MyLightBulb",
            "thingTypeName": "LightBulb",
            "thingArn": "arn:aws:iot:us-west-2:123456789012:thing/MyLightBulb",
            "attributes": {
                "model": "123",
                "wattage": "75"
            },
            "version": 1
        },
        {
            "thingName": "MyOtherLightBulb",
            "thingTypeName": "LightBulb",
            "thingArn": "arn:aws:iot:us-west-2:123456789012:thing/MyOtherLightBulb",
            "attributes": {
                "model": "123",
                "wattage": "75"
            },
            "version": 3
        }
    ]
}

async fn show_things(client: &Client) -> Result<(), Error> {
    let resp = client.list_things().send().await?;

    println!("Things:");

    for thing in resp.things.unwrap() {
        println!(
            "  Name:  {}",
            thing.thing_name.as_deref().unwrap_or_default()
        );
        println!(
            "  Type:  {}",
            thing.thing_type_name.as_deref().unwrap_or_default()
        );
        println!(
            "  ARN:   {}",
            thing.thing_arn.as_deref().unwrap_or_default()
        );
        println!();
    }

    println!();

    Ok(())
}
