Action based on alarm entity

Third party integrations Node-RED
1

Hi!

I have input_datetime.next_alarm which has been created (date/time) from Android phone via hassalarm app. I have a plan to create wakeup light…

How can I start increasing light based on alarm time (if has been set) minus 5 min? This is entity detail if alarm hasn’t been set:

This is what i have been using now for more than a year. Works very reliable:
