CLI

AWS CLI

To associate a thing with a thing type

The following update-thing example associates a thing in the AWS IoT registry with a thing type. When you make the association, you provide values for the attributes defined by the thing type.

aws iot update-thing \
    --thing-name "MyOtherLightBulb" \
    --thing-type-name "LightBulb" \
    --attribute-payload "{"attributes": {"wattage":"75", "model":"123"}}"

This command does not produce output. Use the describe-thing command to see the result.

For more information, see Thing Types in the AWS IoT Developers Guide.

• For API details, see UpdateThing in AWS CLI Command Reference.

suspend fun updateThing(thingNameVal: String?) {
    val newLocation = "Office"
    val newFirmwareVersion = "v2.0"
    val attMap: MutableMap<String, String> = HashMap()
    attMap["location"] = newLocation
    attMap["firmwareVersion"] = newFirmwareVersion

    val attributePayloadVal =
        AttributePayload {
            attributes = attMap
        }

    val updateThingRequest =
        UpdateThingRequest {
            thingName = thingNameVal
            attributePayload = attributePayloadVal
        }

    IotClient.fromEnvironment { region = "us-east-1" }.use { iotClient ->
        // Update the IoT thing attributes.
        iotClient.updateThing(updateThingRequest)
        println("$thingNameVal attributes updated successfully.")
    }
}
