MQTT

LEDBot can connect to a MQTT broker and subscribe to channels for "push" notifications. This functionality is very minimal at the moment and can be expanded upon with additional parameters. By default LEDBot listens to channel ledbot/ on the public broker test.mosquitto.org

JSON Feeds

LEDBot can periodically pull data from arbitrary JSON feeds (ex, weather, quotes, transit times, news articles) and add them to the queue. This functionality is still rough and in development see webFillerHandler.py
