* This class can handle the GPIO outputs for the night light mode.

|
|
* At the lowest brightness setting, the light will switch to night light
|
|
* mode. In the Yeelight integration in Home Assistant, this feature is
|
|
* exposed trough a separate switch. I have found that the switch is both
|
|
* confusing and made me run into issues when automating the lights.
|
|
* Using the lowest brightness for triggering the night light feels a lot
|
|
* more natural.
