A Python script, running on a Raspberry Pi, which eats WebSocket events from Pusher and converts them into door openings.

• pip install https://github.com/ekulyk/PythonPusherClient/archive/master.zip (may require sudo)
• PUSHER_KEY=XXX python poll.py

If you need to use sudo to run the script (which you almost definitely will), can add export PUSHER_KEY=XXX to your /etc/environment so it's available all over the place, then run the script with:

sudo -E python poll.py

You're going to need a relay sitting on GPIO pin 11 of your Raspberry Pi. This will be switched for 3 seconds whenever we get an event from Pusher.
