This QA is designed to allow your lights to be switched on with motion detection from a sensor.  Instead of the usual time settings you can use LUX levels instead.
Please remember that your sensor needs to be able to measure lux levels quite frequently for reliability and is recommended to use this QA with mains operated lux sensors instead of battery operated lux sensors.
Just select Duration, Lux level and whether you want to dimyour lights or not and levels and away you go.
Remember to update the variables.
