2018-08-24 22:44:01 +02:00
------------------------
- **red_channel** (*Optional*): Value of the red color channel relative to the clear channel, as a percentage.
2019-02-17 12:28:17 +01:00
All options from :ref:`Sensor <config-sensor>`.
- **green_channel** (*Optional*): Value of the green color channel relative to the clear channel, as a percentage.
2019-02-17 12:28:17 +01:00
All options from :ref:`Sensor <config-sensor>`.
- **blue_channel** (*Optional*): Value of the blue color channel relative to the clear channel, as a percentage.
2019-02-17 12:28:17 +01:00
All options from :ref:`Sensor <config-sensor>`.
- **clear_channel** (*Optional*): Value of the clear (without a color filter) channel, relative to the maximum value for
the chosen integration time. All options from :ref:`Sensor <config-sensor>`.
- **illuminance** (*Optional*): Get the total illuminance of the sensor in lx.
- **color_temperature** (*Optional*): Get the calculated color temperature of the light in Kelvin.
- **gain** (*Optional*): Set the gain for the internal ADCs to work better in certain low-light conditions. Valid
values are ``1x`` (default), ``4x``, ``16x``, ``60x`` (highest gain).
- **integration_time** (*Optional*): The amount of time the light sensor is exposed. Valid values are
``2.4ms`` (default), ``24ms``, ``50ms``, ``101ms``, ``120ms``, ``154ms``, ``180ms``, ``199ms``,
``240ms``, ``300ms``, ``360ms``, ``401ms``, ``420ms``, ``480ms``, ``499ms``, ``540ms``, ``600ms``, ``614ms``.
- **glass_attenuation_factor** (*Optional*): The attenuation factor of glass if it's behind some glass facia.
Default is ``1.0`` means ``100%`` transmissivity. ``2`` means ``50%`` transmissivity etc.
- **address** (*Optional*, int): Manually specify the I²C address of the sensor. Defaults to ``0x29``.
- **update_interval** (*Optional*, :ref:`config-time`): The interval to check the
2019-01-06 18:56:14 +01:00
sensor. Defaults to ``60s``.
