#******************************************************************************
# This is a more complex home assistant automation that is triggered whenever
# the rotary encoder changes value. 
# The action then uses a series of "choose" decisions to set an RGB lightbulb
# to colours of the rainbow between 1-7. When encoder = 0 the light is turned off
# when encoder is > 7 it sets the bulb to white.
