Garage Door opener With Raspberry Pi, Django, and a Relay

Purpose:

Open or close my garage door by clicking on a website.

Architecture:

Three smaller projects are intertwined in this project.

1. Open the garage door by clicking on a website.
2. Proxy the video stream through the same website. (And same credentials)
3. Sense the state of the garage door through a sensor and Zigbee.

Garage Door Opener

Requirements

1. Open garage door via a website button.
2. User must be authenticated.

Design

1. Use Django for website display and authentication.
2. Use a Raspberry Pi to control a relay wired to the button near the house.
3. Use a python script/CherryPy server to control the raspberry pi. garage.py (This is how the django site interacts with the raspberry pi. It's definitely insecure.)
