Email on Button Push

Just a simple script that runs on a Raspberry Pi that allows an email to go out on a button push.

Requirements

• Python 3
• pip
• sparkpost: pip install sparkpost
• requests: pip install requests (should be installed with sparkpost)
• Raspberry Pi with IO Port 16 connected to a button

Configuration

1. Setup a SparkPost account and create an API Key for the account.
2. Setup the environment variables below.
   1. Set them up under /etc/environment like below.
   2. All are required to run

SPARKPOST_API_KEY=longapikey
BTNPI_FROM_ADDRESS="email@example.com"
BTNPI_TO_ADDRESS="email@example.com"
BTNPI_TO_ANNOUNCE="email@example.com"
BTNPI_SUBJECT="Subject Line"
BTNPI_MESSAGE="Hello, the mailbox button was pressed."

• SPARKPOST_API_KEY environment variable for SparkPost to send messages
• BTNPI_FROM_ADDRESS address that the Pi sends out of
• BTNPI_TO_ADDRESS address that the Pi sends to when the button is pushed
• BTNPI_TO_ANNOUNCE when the Pi turns on it will email the External IP to this address
• BTNPI_SUBJECT subject line in the email
• BTNPI_MESSAGE message to send when the button is pressed

Note: All of these might be best in a JSON file - feel free to submit a PR :)
