aeon labs incorrect lux values

I noticed that the lux values of my 4in1 aeon lbas are sometimes very low, only 2,3 or 4 lux in the evening when all room lights are on.

When i place an other lux meter beside the 4in1 sensor this lux meter returns a complete other lux value of 17 instead of 3 on the 4in1…

Is there a way to ajust the output value of the 4in1 aeon labs sensor value?

Temp and motion work OK (and are correct), humidy i do not use so no idea if the value is accurate or not.

Using this sensor in UI5 setup with vera lite.
