I was able to get the device to receive a couple times, but it seeks to be intermittent Again, thinking it's the sketch internet. Need to feed the squirrels in the router again or something.

Thanks for posting this. I can see how this can be useful.

AWS Setup

1. Log onto your AWS account and pick a supported region for your IoT device. For example:
   https://us-west-2.console.aws.amazon.com/iot/home?region=us-west-2#/thinghub
2. Click on Secure > Policies.
3. Create a new policy and edit it in advanced mode. We're going to create a simple, open policy that is appropriate for development and experimenting. You can name your policy m5stack. Fill the policy contents with this JSON:

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": "iot:*",
      "Resource": "*"
    }
  ]
}

3. Click on 'Things' and then click 'Create'.
4. Click on 'Create a Single Thing'.
5. Give your thing a name. Example: m5stick
6. You can leave the type, group, and attributes settings blank for now. Click Next.
7. Click on the top 'Create Certificate' button.
8. Download the cert file and the private key file. You do not need the public key file. Rename these as simply cert.pem and priv.key. The shorter names are important as they can't be longer than 10 characters.
9. Click the 'Activate' button.
10. Click 'Attach a Policy'. Attach the m5stack policy you created in the previous step. Click 'Register Thing'.

AWS Monitoring

Now you're ready to monitor for published messages.

1. Click on the 'Test' link on the left side of the page.
2. Enter # in the Subscription topic. This is a wildcard that will receive all messages for all topics. Click 'Subscribe to Topic'.
3. View your endpoint. You can find it in the pulldown menu on the upper right:

UIFlow configuration

Finally you can upload your cert and key onto your device, and create some UIFlow code.

1. Connect your device to UIFlow. Create a new MQTT block that looks like this, using your own URL:

2. Change the port to 8883. This is important, don't forget it. AWS runs MQTT on a non-standard port.
3. Click on the plus icon to upload your cert.pem and priv.key files onto your device. They will then be available in the pulldown menus.

4. Finally, run the code on your device. You will now begin to see "hello world" messages appearing in the queue every second:

Here's one last screenshot that includes an example of how to subscribe to messages on your device. In this example you'd Publish a test message to the 'receive' topic. Just make sure you have a label0 somewhere on the screen.
