Night Automation for Dimmed Bathroom Lights

I have an automation that turns on all the bathroom lights (3 GE/Jasco Enbrighten standard switches) based on a motion detector. At night, I want to change this so that only one of the switches turns on and the Hue bulb in the light only lights to 30%, but I’m not sure how to accomplish this. I know how to get the time of day change working and only have the one switch trigger at night, but not how to customize the Hue bulb brightness. I should also add that I do my customization in Node Red and my YAML skills are practically non existent.

Thanks in advance for any help you can provide.
