Fritz!Box tools only shows connected WiFi devices?

Hi,

today I installed the ‘Fritz!Box tools’ integration.
It shows (only) 15 devices. If I compare to Fritz!Box web UI I see that those are the currently connected devices. I am interested in the WiFi devices (mobiles) for presence detection.
Now I want to setup presence detection. But since I can see only connected devices I cannot setup presence detection for people which are not at home.

Is this correct that ‘Fritz!Box tools’ integration only shows connected devices?

Thanks for any help!
