Element Path: <cwt><CORE><externalLight>
This attribute controls the use and the brightness of the door illumination.
The power save function may override the settings made with this attribute. Read more about this in section RFID in CORE element, and in Example of a light setup.
attributes
brightnessMax
| Range: | 0 – 100 |
| Default: | 80 |
| Description: | Brightness in % |
brightnessMin
| Range: | 0 – 100 |
| Default: | 0 |
| Description: | Brightness in % |
brightnessSleep
| Range: | 0 – 100 |
| Default: | 0 |
| Description: | Brightness in % when the terminal is in sleep mode. Can be overrided by brightnessMin if ChangedDuringDarkness is used and brightnessMin should be used when awake. |
darkerThenLessBrightness
| Range: | true / false |
| Default: | false |
| Description: | If true, the light will decrease when it darkens outside. If false, the light will increase when it darkens outside. |
darknessMode
| Range: | Threshold, LinearFromThreshold |
| Default: | Threshold |
| Description: |
•Threshold: The brightness is set to a fixed (min./max.) value depending on whether the measured ambient light is above or below the threshold set for the ambient light sensor.
•LinearFromThreshold: The backlight brightness is changed linearly to the measured ambient light when the measured ambient light is above or below the threshold (depending on the setting of the attribute darkerThenLessBrightness). The hysteresis is not used when LinearFromTreshold mode is selected.
mode
| Range: | AlwaysOff, AlwaysOn, TurnedOnDuringPurchase, ChangedDuringDarkness, TurnedOnDuringPurchaseInDarkness, TimeControlled, TimeControlledExternalOnOff |
| Default: | ChangedDuringDarkness |
| Description: |
•AlwaysOff: The backlight is always off
•AlwaysOn: Always ON except when in sleep mode. attribute brightnessMax defines brightness when turned ON
•TurnedOnDuringPurchase: Turned ON when selection or payment is started. Turned OFF approximately 10 s after Accept is pressed. attribute brightnessMax defines the brightness when turned ON
•ChangedDuringDarkness: The Ambient Light module calculates the brightness value. see ambientLightSensor.
•TurnedOnDuringPurchaseIinDarkness: Turned ON when the Ambient Light module determines that it is dark. The Ambient Light module calculates the brightness value. See ambientLightSensor. The result is only used during a purchase.
•TimeControlled: Time controlled brightness values
•TimeControlledExternalOnOff: Time controlled 12v output
Example:
The external light is switched ON at 40 % brightness during a purchase and is OFF (0 % brightness) in between purchases.
