Script to auto set the brightness of a light based on the time of day.

Features:

Brightness to be based on time of day
Light to be switched via mains switch
On power on, light needs to get time time from NTP, then set brightness
Dim light is needed while its gets the current time (4-6s)
Ability to force max brightness using mains switch

stateDiagram-v2
    ForceMax: Set Light Max Brightness
    state if_failedbootstate <<choice>>
    SetFailedBootsFalse: Set Failed Boot to false
    SetFailedBootsTrue: Set Failed Boot to true
    waitBootTime: Wait for boot time (10s)
    WiFi: connect to wifi (1-5s)
    NPT: get time from NPT (1-2s)
    LoadPereviousFailedBoot: Load the PereviousFailedBoot state
    WaitNtp: Wait for NTP
    TimeBasedBrightness: Set brightness based on time
    BootBrightness: Set Dim brightness

    note right of waitBootTime : If user turns off power before FailedBoot is set to `false`,<br>next power on will be max brightness.
