### CCT light (brightnes and temperature)
This example comes from a configuration of Shelly RGBW Bulb working in White mode.
`max_mireds` and `min_mireds` set color temperature boundaries to 3000K - 6500K. Notice the same limits are applied in `command_on_template`, but in kelvin units this time. It's due to conversion from mired to kelvin which causes exceeding boundary values accepted by the device.
The code also ensures bi-directional conversion of brightness scale between 0-100 (required by the device) and 0-255 (required by Home Assistant).
Add the following to your `configuration.yaml` file:

If you don't want brightness, color or effect support, just omit the corresponding configuration sections.
