aws-iot-phyton-piface-digital2

This project is for connecting a Raspberry Pi with Piface Digital 2 board to AWS IoT (Amazon Web Services Internet of Things).

To get this running for you:

• Create an AWS account if you don't alraeady have one
• Log in into AWS console: https://console.aws.amazon.com
• Go to "Internet of Things" => AWS
• Create a new "Thing"
• Have a client created for you using Linux and Python. Download client and expand the zip file.
• Replace the pem, key and crt files in the project with the files from your downloaded client
• Edit the py file and adjust these values:
  • host
  • certificatePath
  • privateKeyPath
• You may adjust the name sof the topics used for send and receive
• Make the py file runable by running chmod +x garagentor.py
• Make the shell script runable by running chmod +x start_garagentor.sh
• Run the Python script
• Open the AWS IoT console and go to Test
  • In Subscribe to a topic section enter garage/inputs or your changed topic
  • Press buttons on the PiFace Digital 2 board
  • You should see a new message for each button press and each button release
  • In the Publishsection enter garage/outputs or your changed topic
  • For the body enter {"isSet": true, "pin": 0} and push the Publish to topic button.
  • You should hear one relay switching and one LED should light up
  • Use {"isSet": false, "pin": 0} to switch it off again

To run the program as a Linux service using sytemd

Create a service manifest

Create text file /etc/systemd/system/garagentor.service (with sudo or as root) with this contents:

[Unit]
Description=garagentor

[Service]
Type=forking
ExecStart=/home/pi/garagentor/start_garagentor.sh
Restart=always
RestartSec=3

[Install]
WantedBy=multi-user.target

Enable the service (with sudo or as root)

systemctl enable garagentor

Start the service (with sudo or as root)

systemctl start garagentor
