AWS IoT Daemon

A daemon node that sets up a connection to the AWS IoT service.

Setup in AWS IoT Cloud

It needs a device (thing) set up in the AWS cloud per the instructions here: AWS IOT Getting Started

Proper certificates need to be generate and attached to the Thing and policies set up so that this node can access the Thing Shadow using the certs and private key.

The cert, private key and CA cert needs to be downloaded from AWS and placed somewhere in the local file system where the Elixir runtime can access it.

Configure these locations in the application config file.

Example:

# ssl options for the MQTT client
# these get passed to the Erlang ssl module
# see ssl_option() here: http://erlang.org/doc/man/ssl.html
config :exred_node_aws_iot_daemon, :ssl,
  keyfile: "/exred_data/certs/private.pem.key",
  certfile: "/exred_data/certs/certificate.pem.crt",
  cacertfile: "/exred_data/certs/symantec_ca_root.pem"
