CarHole | garage door through a Raspberry Pi

The server runs https on port 443. There is a secret key configured in config.py that must be included in application/x-www-form-urlencoded content type in each request or the request will return a Invalid Key error. A POST request to /operate will operate the door. A POST request to /checkdoor will return Open or Closed. While this script makes efforts to operate securely, nothing is perfect and new vulnerabilites are discovered all the time, be sure to evaluate and mitigate the potential risks by blocking all, or limiting to only port 443, exposure to the Internet and apply updates to keep all components as new fixes are released. Example of a Python script to check door status.
Wire up the Raspberry Pi with the guide above
sudo apt-get install python-pip
sudo pip install flask
Copy SSL cert and key to directory or generate a self-signed one: openssl req -x509 -newkey rsa:4096 -keyout carholekey.pem -out carholecert.pem -days 3650 -nodes
Edit config-example and save as config.py
sudo python carhole.py
