Switch on/off status in the sensors

Hi, I’m new, I come from the Vera system that I integrated into HA to manage devices and scenes.

I added a Zwave USB Dongle to my HA to insert devices but, in the motion sensors or door openers, I don’t see the possibility of a switch to arm or disarm the device, to warn of movement “if armed” or nothing “if disarmed”
That is, I would need each sensor to have an on/off switch for arming/disarming to organize scenes based on state
In Vera system this switch is by default in the sensors but in HA I don’t understand the logic.

Is there a way to view? am I wrong something?
Thank you for the help
