Sensors should include the ARM status attribute without having to create “input_boolean” .yaml files for each sensor.
The use is to switch the sensor mode ON/OFF!
If the sensor is “ARM -OFF” and detects, it performs functions other than “ARM -ON”
There are many uses, perhaps disarming that particular sensor so that it does not perform Automations!
E.g. of automation
I have binary_sensor.window in “ARM -ON” (so the alarm would go off if they open the window) but, if I’m in the room and binary_sensor.room in “ARM -OFF” detects, it sets binary_sensor.window in “ARM -OFF” until I leave the room
