# Alarm script with brightness and color temperature adjustment for ioBroker
#
# This script gradually adjusts the brightness and changes the color temperature from warm white to cool white
# via ioBroker control. It increases brightness from 1 to 100 and changes color temperature from 1600 (warm white)
# to 0 (cool white) within 15 minutes.
#
# After 15 minutes, a color change is triggered.
# Customizable settings:
# - Adjust ioBroker brightness and color temperature commands
set -e  # Stop the script on errors
#set -x  # Enable debugging # Uncomment for a more detailed log
# Debug
DEBUG=false
SSH_EXECUTED=false  # Variable to track SSH command status
