How to Specify Daylight
Daylight linking is very simple technology but needs careful consideration to implement well. Contrary to common belief, sensors cannot measure the lux level on the surface they are pointed at, they can only measure the light level on the sensor itself. Therefore, if it is positioned or aimed incorrectly, it will not function as anticipated.

When you locate a fitting with a daylight sensor it will appear with a yellow circle
Stage 2
...
Tap Profiles [1]
Create a Daylight Sensor and rename as appropriate [2]
Tap LDR and choose Sensor Up or Sensor Down [3]
Select the Daylight Rate and Save Changes [4]
| Info |
|---|
DaylightRate This sets the speed of reaction to changes in daylight. If set to 60 seconds then the sensor will take 10 samples of the daylight over a 60 second period, then slowly dim the lights to the calculated level over the next 60 seconds. |

Tap Luminaires and Configure [5]
Apply the profile to the device [6]
Stage 4
...
Tap Link and Daylight in the bottom left of the 'Luminaires' screen [7]
Link the Daylight Sensor to the lights to be controlled [8]
Stage 5
...
Monitor the reading and adjust sensor if necessary
| Info |
|---|
Sensor High If the sensor is aimed at the inside of a room with dark finishes, or at the floor of a warehouse, then if will be monitoring levels between 1 lux and 100 lux. If the daylight sensor is aimed at a skylight then it will be monitoring light levels between 10 lux and 10,000 lux. By default, daylight sensors are set to operate in the 1 lux to 100 lux range. If you find that the Sensor Reading is high when you would expect it to detect a reduction in Daylight level, then Tick the Sensor High reading in the profile. This will change the electronics within the device to work at the higher range. |
Stage 6

Go to Configure [9]
Set the Target Level(s) in the Sensor [10]
Once this step is complete the daylight sensor is commissioned and Stage 7 is optional
...
Tap on a specific luminaire(s) in Configure [11]
Tap Min Daylight Level [12]
Modify the behaviour of different target luminaries by setting their Min Daylight Level [13]
On The Dashboard
The effect of these settings can be reviewed on the Dashboard by clicking on the Daylight Sensor and/or affected lights in the Drawings view.
