How to configure a daylight sensor for Daylight harvesting using the Lumos Controls mobile app?

Go to the 'Devices' tab
Click on the icon of the daylight sensor to be associated with the light device or group
Select the 'Daylight sensor settings' option
Configuration
1. Sensitivity: Configure sensitivity to define the time interval at which the daylight sensor shall check for changes in the light falling on it
  
  i. The default value for this interval is 10 sec and can be configured between 10-2540 sec
2. Tolerance: Configure tolerance to define the allowable deviation from the configured light level. The daylight sensor will not send triggers on reading light levels with variation within the tolerance limit from the actual configured light level.
  
  i. Tolerance is applicable only if the daylight sensor is configured in 'Closed Loop' or 'Custom' modes
  
  ii. The default value for this setting is 20 lux and can be configured between 1-100 lux
  
  For example: If you configure the light level to be maintained by the daylight sensor using Closed Loop as 200 lux and set tolerance as 10 lux, the daylight sensor will not send any triggers on detecting a lux level in the range 190-210 lux.
c. Fade Time: Configure Fade time to define the time with which the light device shall transition to the level specified by the daylight sensor
1. 1. The default value for this is 1 sec and can be configured between a range of 0 to 25.4 sec
