Master switch and user configurable light modes

[RubenKelevra]

While the automatic is great, there's quite some amount of boilerplating necessary for a real world setup right now.

Master Switch

It would be nice to have a master switch, which could just be linked with a 1:1 automation to the light switches which turns on/off all configured lights.

Profiles

It would be nice to have something like scenes with a name, brightness setting and color temperature and the standard "auto" as a drop down list instead of just an on/off switch.

This way we could create an interface similar to the one used for climate, which has profiles and automatic / manual and off.

Manual just overrides and gives the user manual control over the whole "lightgroup" Adaptive Lighting is controlling with the usual butter smooth transitions, switching back to auto will start changing it back to the calculated automatic.

We already have one profile: night/sleep mode.

The user would just enter his own the brightness percent and the Kelvin in a list with a name and those will be available to select.

Limiter

This would allow pretty rapid changes in light temperature, which isn't really healthy.

I would recommend to add a limiter which calculates how large the difference is in perceived color temperature change (mired) and slows it down if it's too fast.
