I have been working on a new subsystem to complement Home Assistant's Automation and Scripting components. `AppDaemon` is a python daemon that consumes events from Home Assistant and feeds them to snippets of python code called "Apps". An App is a Python class that is instantiated possibly multiple times from `AppDaemon` and registers callbacks for various system events. It is also able to inspect and set state and call services. The API provides a rich environment suited to home automation tasks that can also leverage all the power of Python.
