Effective CPU use

Is it better to use this automation:

  • alias: ‘Turn off PIRs’
    initial_state: ‘on’
    trigger:
    • platform: state
      entity_id: switch.pirsklep
      to: ‘on’
      action:
    • delay: ‘00:00:02’
    • service: switch.turn_off
      entity_id: switch.pirsklep

For every motion sensor. So if you have 5 sensors, you will have 5 similar automations or create a single where will be OR for entity_id´s concerning to CPU? Thanks.
