Ready for others to try?

[GollyJer]

Hi! I stumbled on this today while searching for newer circadian light solutions for Home Assistant.
Is this ready for others to try out? I gave it a go but it didn't work.

1. How do I Check that astral dependency installed correctly?

2. I'm seeing this warning.

Logger: homeassistant.components.light
Source: helpers/deprecation.py:257
integration: Light (documentation, issues)

The deprecated constant ATTR_COLOR_TEMP was used from lumaflow. It will be removed in HA Core 2026.1. Use kelvin equivalent (ATTR_COLOR_TEMP_KELVIN) instead, please report it to the author of the 'lumaflow' custom integration

3. and this error
