You can have it set more intelligently than on/off.
For example, what I have (I’m excessive btw, so this is just one option) is a light sensor that tells me how light it is outside, and then combine that information with sunrise/sunset times.
I use that to set the color of the lighting (circadian lighting style), the light level, and a ramp time to the max brightness I’d want. For rooms where there is good daylight coming in, if the light coming in from daylight is bright enough, the lights lower their brightness (daylight harvesting approach).
This isn’t in every room at the moment, as some of my lights are not RGBW LEDs. Those with regular white LEDs just dim.
Is it perfectly set for your eyes? No, but you can tweak it. My wife likes it bright than me, so I set values that I could tolerate for a nice compromise.
No RGB? Then drop the circadian lighting, keep the rest.
No light sensors? There are some APIs available out there for solar radiation values you can use (openweathermap for example). Less accurate, but probably close enough for what you want.
TL;DR version: add more conditions, and get what you want.
You wake up one day with a bad headache, and bright light hurts your eyes. You can close the curtains, but every room is set to turn the lights on to the brightness that you usually prefer.
How do you manage something like this? Do you have to adjust everything with your phone and reset it when you feel better?
Well that’s not ever been an issue for me, that said I do have a flat override to disable and set specific values. But that’s just one toggle (to disable the lighting automations) and one value (light level).
But my eyes are pretty sensitive to light in general, which is why I like the slow ramp up.
