DjangoCon Europe 2016 - Django for IoT: From Hackathon to Production

Speaker: Anna Schneider (twitter) has a PhD in biophysics and learned Django at the Hackathon where whe started WattTime. See also here.


Internet of Things is meant when something that is not typically a computer transmits data and maybe even responds to control. IoT can involve embedded programming, but many things just have usable APIs.


  • Use db_index early and on timestamps, because you will have loads of data.
  • use tasks instead of views
    • tasks initiate actions
    • tasks may monitor (pull attributes and statuses)
    • tasks may control (set attributes and statuses)
  • since tasks run async, pass pks and not objects
  • encapsulate the client/vendor library so that you can swap out devices
  • break up into apps for production
    • devices: Device models, later maybe views for devices.
    • observations: Data models, later analytics views.
    • interactions:, later on administration
    • vendor: wrapper for client libraries
  • use celery for async tasks
    • don't use RabbitMQ to persist things, redis may work
  • use the cookiecutter

IoT can actually improve the world, so go out there and try it.
