Meaning of "Turn on group with last settings"

Hello everyone,

my Kitchen Lights are switched on when i access the Sensor in the Floor.
I intended to configure that Floor-Ligts are switched on when accessing the Floor.

I assume that it does relates to my Sensor-Configuration “Turn on group with last settings”.

What does “Last Settings” mean?

I did not find any Description in the Manual.

Kind Regards
Stephan
