Created by Usha Nandhini, Modified on Thu, 18 Jan 2024 at 07:05 AM by Nishin Menon

This method can be used by the users who want to maintain the current ambient lighting they are currently exposed to, but are unaware of the exact Lux values to be configured to the daylight sensor.


  1. Go to the 'Devices' tab
  2.  Click on the  icon of the sensor
  3. Choose the 'Daylight sensor settings' option
  4. Go to 'Daylight harvesting mode' and click on the 'Closed Loop' tab
    processed (243)
  5. Click on the 'Configure Closed Loop' button
  6. The option 'Maintain Current Light Level'' will be selected by default
  7. Ensure that the light devices or group to be controlled by the daylight sensor are associated with it 
  8. Click on the 'Read' button to read the current light level detected by the sensor
  9. The light falling on the sensor will be different from the light falling on the workstation
  10. Let's note down the light that is falling on the workstation now
    1. To do this, place a lux meter at the workstation 
    2. Note down the lux meter reading and enter it in the app
    3. This value is noted only for future purposes to identify the light at the workstation when the sensor reads a particular value
  11. Click on the 'Set' button, and the value to be maintained by the sensor will be configured
