Can Home Assistant trigger based on security system contact or motion sensors?

Configuration

Can Home Assistant reliably trigger actions/routines, based on security system contact sensor or motion sensor events/states?

In particular, I am considering both Ring and DSC (PowerG) for alarm systems, and will be going with Lutron Radio RA3 for lighting (and understand there are still a lot of open questions about it’s ability to integrate). For clarity, I want the alarm system to continue to function with all it’s native functionality, just be able to trigger other events.

Thanks!

I have a DSC 1832 and use my door and window sensors. I am connecting to HA with an IT100 with code to make it appear like an Envisalink. I use shelly motion sensor and trigger with them.

Two examples:

  alias: Mud Room Light on when Garage Entry Door Opens
  description: Turn on the light for 60 seconds when Door Opens
  trigger:
  - platform: state
    entity_id: binary_sensor.garage_entry_door
    from: 'off'
    to: 'on'
  condition: []
  action:
  - service: switch.turn_on
    target:
      entity_id: switch.mud_room_light
  - delay:
      seconds: 60
  - service: switch.turn_off
    target:
      entity_id: switch.mud_room_light
  mode: single

  alias: Hallway - Turn on Light
  description: When motion detected turn on light
  trigger:
  - platform: state
    entity_id: binary_sensor.motion_detector
    to: 'on'
  condition: []
  action:
  - service: switch.turn_on
    target:
      entity_id: switch.hallway_cans
  - wait_template: ''
    timeout: 00:01:00
  - service: switch.turn_off
    target:
      entity_id: switch.hallway_cans
  mode: single
