"""Interact with TPLink Light Presets.

>>> from kasa import Discover, Module, LightState
>>>
>>> dev = await Discover.discover_single(
>>>     "127.0.0.3",
>>>     username="user@example.com",

Light presets are accessed via the LightPreset module. To list available presets

>>> light_preset = dev.modules[Module.LightPreset]
>>> light_preset.preset_list
['Not set', 'Light preset 1', 'Light preset 2', 'Light preset 3',\
 'Light preset 4', 'Light preset 5', 'Light preset 6', 'Light preset 7']

To view the currently selected preset:

>>> light_preset.preset
Not set

To view the actual light state for the presets:

>>> len(light_preset.preset_states_list)
7

>>> light_preset.preset_states_list[0]
LightState(light_on=None, brightness=50, hue=0,\
 saturation=100, color_temp=2700, transition=None)

To set a preset as active:

>>> dev.modules[Module.Light].state  # This is only needed to show the example working
LightState(light_on=True, brightness=100, hue=0,\
 saturation=100, color_temp=2700, transition=None)
>>> await light_preset.set_preset("Light preset 1")
>>> await dev.update()
>>> light_preset.preset
Light preset 1
>>> dev.modules[Module.Light].state  # This is only needed to show the example working
LightState(light_on=True, brightness=50, hue=0,\
 saturation=100, color_temp=2700, transition=None)

You can save a new preset state if the device supports it:

>>> if light_preset.has_save_preset:
>>>     new_preset_state = LightState(light_on=True, brightness=75, hue=0,\
 saturation=100, color_temp=2700, transition=None)
>>>     await light_preset.save_preset("Light preset 1", new_preset_state)
>>> await dev.update()
>>> light_preset.preset  # Saving updates the preset state for the preset, it does not \
set the preset
Not set
>>> light_preset.preset_states_list[0]
LightState(light_on=None, brightness=75, hue=0,\
 saturation=100, color_temp=2700, transition=None)

If you manually set the light state to a preset state it will show that preset as \
    active:

>>> await dev.modules[Module.Light].set_brightness(75)
>>> await dev.update()
>>> light_preset.preset
Light preset 1
