You can choose which sensors are armed in Home and Away mode, or both, or always active.
Sensor set to 'Away' & 'Home' mode

Sensor set to 'Away' mode

If you want to avoid triggering the alarm when you are at home, you can set the specific sensor in Away mode. Then when you set the panel in “Home” state, the alarm will not be triggered, only when you set the panel in “Away” state, the alarm will be triggered.
