Created by Usha Nandhini, Modified on Thu, 18 Jan at 7:07 AM by Nishin Menon

Choose this method if the user clearly knows what Lux value is to be maintained at his workstation (area where he wants his desired lighting) but is unaware of the Lux value 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. Scroll down to 'Daylight harvesting mode' and click on the 'Closed Loop' tab
  5. Click on the button, 'Configure Closed Loop'
    processed (243)
  6. Select the 'Identify Desired Light Level' option
  7. Make sure that the light devices or group to be controlled by the daylight sensor are associated with it 
  8. Place a lux meter at the workstation and note its reading
  9. Verify if the desired light level is detected at the workstation
  10. If not, use the intensity slider shown in the app screen to adjust the electric lighting until the lux meter placed at the workstation reads the desired level
  11. When the lux meter reads the desired light level, click on the 'Read' button to read the light level detected by the sensor at this point
  12. The light falling on the sensor and the light falling on the workstation will be different
  13. Enter the lux meter reading in the app
    1. This value is noted only for future uses to identify the light detected by the sensor when desired light falls on the workstation 
  14. Click on the 'Set' button, and the value to be maintained by the sensor will be configured
