# NodeRED flow to update Thing shadows in AWS IoT from a TTN app.

It opens a connection to [a TTN app](https://staging.thethingsnetwork.org/) on the incoming side and a connection to the [AWS IoT](https://aws.amazon.com/iot/) MQTT broker on the outgoing side. Anything posted to the TTN app will be relayed to the according Thing shadow (based on the `devEUI`) on the AWS side.

## Flow

![NodeRED flow](images/flow.png)

This example flow for NodeRED needs a [contrib node for TTN](https://www.npmjs.com/package/node-red-contrib-ttn) which you must install.

Alternatively you can use my [resin.io](http://www.resin.io)-based [NodeRED for TTN image](https://github.com/thesolarnomad/resin-node-red-ttn) to make it work out of the box on a RaspberryPi.

## Getting started

Create a new Thing (the name must be a valid `devEUI` with leading zeros):

![AWS ioT](images/AWS_IoT.png)

with a certificate (download them!) and a policy:

```json

{

  "Version": "2012-10-17",

  "Statement": [

    {

      "Action": [

        "iot:*"

      ],

      "Resource": [

        "*"

      ],

      "Effect": "Allow"

    }

  ]

}

```

Then update the flow (`flow.json`):

* replace `` and `` of the TTN node.

* update the broker host: `XXX.iot.XXX.amazonaws.com` to match what is shown as `REST API endpoint` when you look into the details of your created Thing in AWS IoT.

* put the certificates into the right spot and/or update the paths.

and finally import your adapted flow into NodeRED.
