## Kelvin!
## Color temperatures in Kelvin
{% details "TODO" %}
Another [WTH topic](https://community.home-assistant.io/t/wth-is-light-temperature-not-in-kelvin/467449)
that was voted for almost 150 times! Why doesn't Home Assistant use Kelvin
for color temperatures?
- Improve extend story
- Add reference to WTH
- Spelling/grammar

* Use color temperatures in Kelvin in more_info_light (#14016) @emontnemery
- Adapt homekit to color temperatures in K ([@emontnemery] - [#79713]) ([homekit docs]) (noteworthy)
- Use Kelvin as the preferred color temperature unit ([@emontnemery] - [#79591]) ([light docs]) (noteworthy)
- Migrate Shelly to use kelvin for color temperature ([@thecode] - [#79880]) ([shelly docs]) (noteworthy)
- Update Fritz! lights to use kelvin ([@flabbamann] - [#79733]) ([light docs]) ([fritzbox docs]) (noteworthy)
- Migrate the LIFX integration to use kelvin for color temp ([@Djelibeybi] - [#79775]) ([lifx docs]) (noteworthy)
Well, a small piece of history: The Home Assistant story started using Philips
Hue a long, long time ago. And Hue uses mired for its color temperature,
not Kelvin.
{% enddetails %}
But today, Kelvin is much more commonly used. It is even on packages of the
bulbs you buy. So, as of today, Home Assistant uses Kelvin too!
Also a [WTH topic](https://community.home-assistant.io/t/wth-is-light-temperature-not-in-kelvin/467449)
that was voted for almost 150 times! Why doesn't Home Assistant
use Kelvin for color temperatures? Well... now we do!

Integrations that now use native kelvin instead of mireds: [HomeKit], [Shelly],
[AVM FRITZ!SmartHome], [LIFX]
Kelvin is now the primary color temperature unit. This means all lights
and everything color temperature related shown in the user interface,
are now in Kelvin.
We still do support the good old mired. Mireds are still working and
automatically converted when needed, so this is not a breaking change 🎉
Additionally, integration can now optionally use Kelvin directly if the
device or service accepts that. [HomeKit], [Shelly],
[AVM FRITZ!SmartHome], and [LIFX] are all now using Kelvin natively.
[AVM FRITZ!SmartHome]: /integrations/fritzbox
[HomeKit]: /integrations/homekit
[LIFX]: /integrations/lifx
[Shelly]: /integrations/shelly
The good old mired are still working as well (conversion is done when needed),
so this is not a breaking change 🎉
## Long-term statistics in the entity dialogs
The "more info" dialogs of entities now use long-term statistics for
