In my opinion, the illuminance value of the Vallhorn sensor is ten times too low.
I have compared the values ​​with the values ​​of the Aqara and Fibaro sensors.

Not anymore needed

Modified ikea Vallhorn subdriver to multiply by 10 the default formula result for illuminance, prior to math.floor

local lux_value = math.floor((math.pow(10, (value.value - 1) / 10000) * 10)

Now lux values are higher.
I will do more tests at some point.

Formula

Number Field 1 = Illuminance Measurement from Ikea Vallhorn Sensor
Number Field 2 = Correction Factor
Calculation Result = Corrected Illuminance Measurement
