How to manually set zone occupation

My home behaves differently depending of the occupation of the home zone. E.g. all automations triggered by motion sensors are turned off when no one is at home so my two cats don’t turn on the lights when no human being is at home.

Today it happened again: my phone’s battery was empty before I returned home and I had to run to my dashboard tablet to turn off my alarm system with no lights on.

Is there a way to manually set zone occupation for such situations? I want to tell Home Assistant that someone is home even though the tracked phone is out of power.
