You can schedule LIFX day & dusk bulbs to adjust their Kelvin over the course of the day, in much the same was as f.lux and Night Shift.
But, if you're still using non-smart wall switches, then it's likely that come the next day - when you switch the bulb on it will be the wrong Kelvin.
Example: Go to bed at night, with ultraWarm. Wake up, turn light on, still ultraWarm :( when it should be softDaylight
It's a shame LIFX bulbs don't process the schedules when the light is turned on, that would help. In the meantime, this script is an attempt to fix the problem. Albeit with a slight delay when resuming an appropriate Kelvin.
This script effectively makes the colour wheel in the mobile app redundant, as any change will be automatically overridden. But, you can still use the brightness controls.
