Yes.
A smart bulb with controllable color temperature can be configured to be whiter in the day and warmer into the evening and night. The idea is to better mimic the sun to reinforce our circadian rhythm, and improve sleep. I believe Home Assistant has at least two integrations that can control lights this way.
vs recently there are new dimmable LEDs that automatically change to whiter when bright and warmer when dim, similar to the natural behavior of incandescent bulbs.
These are two different approaches that probably have very similar results (since I already have an automation to dim as it gets later)
Maybe HASS is better than this but it’s not simple to schedule Hue to have the right colours at the right time. At least, not at my latitude. I’ve got separate summer and winter schedules and that helps a lot, but especially in the summer it’s pointless using the built in sunset/sunrise events.
I love the idea of these bulbs. I'm using the adaptive lighting component so my bulbs' temperature and brightness are always correlated anyway. For light fixtures with more than one bulb, a single smart dimmer could replace a whole zigbee light group.
However, are there any bulbs on the market yet with a good temperature range? So far, the only ones I've been able to find are Philips Warm Glow lamps that only go from 2200K to 2700K, which is way too warm for daytime use.
Test, please ignore.
