Note

For production code it is strongly recommended to use the custom endpoint for your account (retrievable via the iot describe-endpoint command) to ensure best availability and reachability of the service. The default endpoints (intended for testing purposes only) can be found at https://docs.aws.amazon.com/general/latest/gr/iot-core.html#iot-core-data-plane-endpoints

Examples

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal's quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To update a thing shadow

The following update-thing-shadow example modifies the current state of the device shadow for the specified thing and saves it to the file output.txt.

aws iot-data update-thing-shadow \
    --thing-name MyRPi \
    --payload "{"state":{"reported":{"moisture":"okay"}}}" \
    "output.txt"

The command produces no output on the display, but the following shows the contents of output.txt:

{
    "state": {
        "reported": {
            "moisture": "okay"
        }
    },
    "metadata": {
        "reported": {
            "moisture": {
                "timestamp": 1560270036
            }
        }
    },
    "version": 2,
    "timestamp": 1560270036
}
