'f.lux'-like app for Ikea Tradfri white spectrum smart bulbs and gateway.
Files:
tradfri.py is the main package handling light control & transition logic.
light-schedule.py is a wrapper for tradfri.py which provides command line argument parsing, and defines a mapping of friendly device names to HomeAssistant IDs. Cronjobs will call this script to initiate state transitions.
lights-auto.py is a utility run on your primary Windows machine in the office where lights are located. During daytime, it will transition lights to 'daytime' state based on mouse/keyboard activity. This is required because lights can't transition state when there's no power to them, so turning power on to the lights won't automatically set them in a state which was sent to the hub while they were off.
automations.yaml is an example HomeAssistant automation triggered by lights-auto.py.
monitor.py is a debugging script to show details of state transitions as they happen.
