Calibrating the Light Level Setpoint

See: Sensor Calibration Task Video.

Unlike the temperature sensor, the light sensor does not require calibration. The light level reported by the hub indicates how much light is detected hitting the surface where the hub is located on the ceiling. This will invariably differ from the light level at different locations in the space, such as an occupant's desk, for example.

Therefore, we have included a light level setpoint that can be used to record the light level the hub reports when the space is at the desired level.

To 'calibrate' the setpoint, manually adjust the lighting in the space until it is at the desired brightness, then enter the hub's current lux reading into the desired light level field. Save your changes.

Important: Make sure you have the correct units set before you calibrate your light levels. 

The setpoint can then be used as the baseline to compare against the hub's current lux reading for lighting control applications. 

Notes:

• When using Proviso to set calibration values, once you apply settings to the hub, the calibration values get stored in your local Proviso app data. If you are using a newly connected hub, you must re-enter a new value to override the previous value stored. 
• For newly connected hubs, a warning icon displays indicating the device already has light calibration value. The warning icon is a normal behavior and will disappear once you enter your desired light level and apply your changes.
