Did you figure out this error, I have the same happening

@jrsecor
I have been struggling with the same issue. I finally read the documentation again and realized I had missed a key step. This script requires a few sensors to be added to the configuration.
https://community.home-assistant.io/t/wake-up-light-alarm-with-sunrise-effect/255193#prerequisites-1

Once I added these, and restarted HA, the blueprint started to work.

sensor:
  - platform: time_date
    display_options:
      - 'date'
      - 'date_time_iso'

New error with 2012.12.7
2021-12-29 15:40:00 WARNING (MainThread) [homeassistant.helpers.template] Template warning: 'as_timestamp' got invalid input 'unavailable' when rendering template '{{0 < as_timestamp(states(sensor) if sensor != 'none' else states('sensor.date') ~ ' ' ~ manual_time) - as_timestamp(states('sensor.date_time_iso')) <= float(seconds) and states(check_entity) in ['unknown', 'on', 'home']}}' but no default was specified. Currently 'as_timestamp' will return 'None', however this template will fail to render in Home Assistant core 2022.1

##improvement:
Is it possible to add xy color transition before the color temperature adjustment?
In example, with a RGBW bulb, at first red to orange color and second warmer to white temperature color.
As RGB leds gets lower brightness than W led, as i was testing, may it be red 1% brightness to orange 100% brightness. And then 1% brightness warmer temperature to 100% of coldest temperature.
What do you think?
Great work ;)

I'd like to be able to use a boolean sensor for check_entity.
I tried adding several items to the "in" list (below) to lines 116 and 124, from

...and states(check_entity) in [''unknown'', ''on'', ''home'']}}'
to
...and states(check_entity) in [''unknown'', ''on'', ''home'', *stuff i've tried*]}}'

but have had no success.

stuff I've tried:

• true
• 'true'
• 1
• '1'
• Boolean(true)
