ThingLoad - An AWS IoT Demonstrator

This is a sample project to push the CPU load of a windows machine to AWS IoT using python.

It shall demonstrate the use of the device shadow.

It uses the AWSIoTPythonSDK https://github.com/aws/aws-iot-device-sdk-python.

Features:

• Fetch CPU load from Windows (done)
• Publish the CPU load to an AWS IoT shadow (done)
• The publish rate is a Shadow Attribute and can be changed (proposed) by others (planned)

Installation

Minimum Requirements

• Python 3.5+

• Windows 7+ (because it calls windows commands to fetch the cpu load)

• OpenSSL version 1.0.1+ (TLS version 1.2) compiled with the Python executable for X.509 certificate-based mutual authentication

  To check your version of OpenSSL, use the following command in a Python interpreter:

  >>> import ssl
  >>> ssl.OPENSSL_VERSION

Usage

python -m thingload -r <rootCAFilePath> -c <certFilePath> -k <privateKeyFilePath>

Example: python -m thingload -r "D:VeriSign-Class 3-Public-Primary-Certification-Authority-G5.pem" -k "D:1234567890-private.pem.key" -c "D:1234567890-certificate.pem.crt" -t MyComputer
