[joey-90]

Add switch to dim light at night, to dim the listen light at night useful if device is in bedroom etc.

I think I fat fingered the wrong button, also thanks for catching my mistake. I made an error copying across my code.

Just noticed this pull request which is similar to a feature that I've just added for the S3 Box devices: https://github.com/esphome/firmware/issues/126

Curious if maybe the nomenclature should potentially be the same for both since the concepts are similar? Also, by chance know if the green LED can be turned off?

Could You also please add the values for :

            red: 100%
            green: 89%
            blue: 71%
            brightness: 60%
            effect: none

to the configurable / options aue in Device UI HA settings ?

To configure these main/default settings for reset_led script. Because I would like to defer and see when the Use_wake_word enabled by the cl of the light : green = use_wake-word enabled and ready to use/device and connnected to WiFi & HA. white led/light = use_wake-word DISabled (in the living room when the tv/music is on and the button (on the Atom Echo) has to be pushed) but its ready to use/device and connnected to WiFi & HA.

Now I do it by this automation & scene with the right brightnessa red,green,bluttings in Home assistant:

alias: M5Stack NR1 light Brightness above 30 description: "" trigger:
