[Hobby] Morning alarm with Apache Airflow DAG

My first Airflow DAG

Following Directed Acyclic Graph(DAG) is built to wake me up gracefully

• First node in the following DAG blinks two of my bedroom Philips Hue lights. At the very end, the node leaves the lights in a dim state.
• Second node sleeps for about 30 seconds(configurable) so that light stays dim and this routine isn’t all that annoying :)
• Next two nodes essentially repeat the first two steps. This gives me enough time to wake up.
• The last node sets maximum brightness and exits the DAG workflow.

Note: For this process to be effective, please do not have any voice assistant in your bedroom. You may turn off the lights and this routine won’t be effective anymore :)

Technical Details

• Programmed Phillips Hue API endpoints to change states of the bedroom lights.
• It is quite easy to plugin python functions into Airflow DAG. Kindly refer the following code snippet to get a feel of ease of integration.

Future plans: Add node to the DAG to have preferred wake up tone. Currently the schedule executes daily but would want it to run only on Weekdays.
