To initialize, you have to await :func:`update()` at least once. This will allow accessing the properties using the exposed properties. All changes to the device are done using awaitable methods, which will not change the cached values, so you must await :func:`update()` to fetch updates values from the device. Errors reported by the device are raised as :class:`KasaException <kasa.exceptions.KasaException>`, and should be handled by the user of the library. Examples: >>> import asyncio >>> bulb = IotBulb("127.0.0.1") >>> asyncio.run(bulb.update()) >>> print(bulb.alias) Bulb2 Bulbs, like any other supported devices, can be turned on and off: >>> asyncio.run(bulb.turn_off()) >>> asyncio.run(bulb.turn_on()) >>> asyncio.run(bulb.update()) >>> print(bulb.is_on) True You can use the ``is_``-prefixed properties to check for supported features: >>> bulb.is_dimmable True >>> bulb.is_color True >>> bulb.is_variable_color_temp True All known bulbs support changing the brightness: >>> bulb.brightness 30 >>> asyncio.run(bulb.set_brightness(50)) >>> asyncio.run(bulb.update()) >>> bulb.brightness 50 Bulbs supporting color temperature can be queried for the supported range: >>> bulb.valid_temperature_range ColorTempRange(min=2500, max=9000) >>> asyncio.run(bulb.set_color_temp(3000)) >>> asyncio.run(bulb.update()) >>> bulb.color_temp 3000 Color bulbs can be adjusted by passing hue, saturation and value: >>> asyncio.run(bulb.set_hsv(180, 100, 80)) >>> asyncio.run(bulb.update()) >>> bulb.hsv HSV(hue=180, saturation=100, value=80) If you don't want to use the default transitions, you can pass `transition` in milliseconds. All methods changing the state of the device support this parameter: * :func:`turn_on` * :func:`turn_off` * :func:`set_hsv` * :func:`set_color_temp` * :func:`set_brightness` Light strips (e.g., KL420L5) do not support this feature, but silently ignore the parameter. The following changes the brightness over a period of 10 seconds: >>> asyncio.run(bulb.set_brightness(100, transition=10_000)) Bulb configuration presets can be accessed using the :func:`presets` property: >>> bulb.presets [IotLightPreset(index=0, brightness=50, hue=0, saturation=0, color_temp=2700, custom=None, id=None, mode=None), IotLightPreset(index=1, brightness=100, hue=0, saturation=75, color_temp=0, custom=None, id=None, mode=None), IotLightPreset(index=2, brightness=100, hue=120, saturation=75, color_temp=0, custom=None, id=None, mode=None), IotLightPreset(index=3, brightness=100, hue=240, saturation=75, color_temp=0, custom=None, id=None, mode=None)] To modify an existing preset, pass :class:`~kasa.interfaces.light.LightPreset` instance to :func:`save_preset` method: >>> preset = bulb.presets[0] >>> preset.brightness 50 >>> preset.brightness = 100 >>> asyncio.run(bulb.save_preset(preset)) >>> asyncio.run(bulb.update()) >>> bulb.presets[0].brightness 100 """ # noqa: E501 LIGHT_SERVICE = "smartlife.iot.smartbulb.lightingservice" SET_LIGHT_METHOD = "transition_light_state" emeter_type = "smartlife.iot.common.emeter" def __init__( self, host: str, *, config: DeviceConfig | None = None, protocol: BaseProtocol | None = None, ) -> None: super().__init__(host=host, config=config, protocol=protocol) self._device_type = DeviceType.Bulb async def _initialize_modules(self): """Initialize modules not added in init.""" await super()._initialize_modules() self.add_module( Module.IotSchedule, Schedule(self, "smartlife.iot.common.schedule") ) self.add_module(Module.IotUsage, Usage(self, "smartlife.iot.common.schedule")) self.add_module( Module.IotAntitheft, Antitheft(self, "smartlife.iot.common.anti_theft") ) self.add_module(Module.IotTime, Time(self, "smartlife.iot.common.timesetting")) self.add_module(Module.Energy, Emeter(self, self.emeter_type)) self.add_module(Module.IotCountdown, Countdown(self, "countdown")) self.add_module(Module.IotCloud, Cloud(self, "smartlife.iot.common.cloud")) self.add_module(Module.Light, Light(self, self.LIGHT_SERVICE)) self.add_module(Module.LightPreset, LightPreset(self, self.LIGHT_SERVICE)) @property # type: ignore @requires_update def _is_color(self) -> bool: """Whether the bulb supports color changes.""" sys_info = self.sys_info return bool(sys_info["is_color"]) @property # type: ignore @requires_update def _is_dimmable(self) -> bool: """Whether the bulb supports brightness changes.""" sys_info = self.sys_info return bool(sys_info["is_dimmable"]) @property # type: ignore @requires_update def _is_variable_color_temp(self) -> bool: """Whether the bulb supports color temperature changes.""" sys_info = self.sys_info return bool(sys_info["is_variable_color_temp"]) @property # type: ignore @requires_update def _valid_temperature_range(self) -> ColorTempRange: """Return the device-specific white temperature range (in Kelvin). :return: White temperature range in Kelvin (minimum, maximum) """ if not self._is_variable_color_temp: raise KasaException("Color temperature not supported") for model, temp_range in TPLINK_KELVIN.items(): sys_info = self.sys_info if re.match(model, sys_info["model"]): return temp_range _LOGGER.warning("Unknown color temperature range, fallback to 2700-5000") return ColorTempRange(2700, 5000) @property # type: ignore @requires_update def light_state(self) -> dict[str, str]: """Query the light state.""" light_state = self.sys_info["light_state"] if light_state is None: raise KasaException( "The device has no light_state or you have not called update()" ) # if the bulb is off, its state is stored under a different key # as is_on property depends on on_off itself, we check it here manually is_on = light_state["on_off"] if not is_on: off_state = {**light_state["dft_on_state"], "on_off": is_on} return cast(dict, off_state) return light_state @property # type: ignore @requires_update def _has_effects(self) -> bool: """Return True if the device supports effects.""" return "lighting_effect_state" in self.sys_info async def get_light_details(self) -> dict[str, int]: """Return light details.
