Fine, I will do change.

I saw the attribute appear as
in_illuminance_input
in_illuminance_scale
in_intensity_raw
in_proximity_raw
in_proximity_sampling_frequency


As I have not set  the .indexed to non-zero,  I will go as non-indexd 
name like
in_proximity_sampling_frequency_available.

I think should be in_illuminance_scale_available
