Brightness Sensor
To get information about the measured light intensity, you can query the brightness sensor.
Due to tolerances in the brightness sensor electronics, it might be necessary to correct the
measured value.
If you want to switch on a certain brightness level (e.g for determing the difference between
day/night), you can use the Threshold value switch communication object. A
If the Lux Hysteresis is different from 0, then the switch object will be set to 0 only when the
measured light level is below the threshold minus hysteresis value.
