Newbie - trigger function

Configuration
#1

Hello everybody,
I have automation,which torn on / of switch when some device change status from / to home. Automation is working well, but I feel like it can be written in some mor sophisticated way. Somethong shorter with IF / ELSE maybe… What would be best syntax?

  alias: PowerOnNotebook
  description: ''
  trigger:
  - entity_id: device_tracker.notebook
    from: not_home
    platform: state
    to: home
  condition: []
  action:
  - data:
      entity_id:
      - switch.63743864dc4f22d434c2
    service: switch.turn_on
    
- id: '1572906181158'
  alias: PowerOffNotebook
  description: ''
  trigger:
  - entity_id: device_tracker.notebook
    from: home
    platform: state
    to: not_home
  condition: []
  action:
  - data:
      entity_id:
      - switch.63743864dc4f22d434c2
    service: switch.turn_off

Please read point 11 here and edit your post accordingly.

Done. Thank you for warning :slight_smile:

Thank you. If you really want to introduce another level of complexity you can do this:

 alias: PowerNotebook
 trigger:
   platform: state
   entity_id: device_tracker.notebook
 action:
   service_template: >
     {% if trigger.to_state.state == 'home' %}
       switch.turn_on
     {% else %}
       switch.turn_off
     {% endif %}
   entity_id: switch.63743864dc4f22d434c2

Thanks. This is exactly what I was looking for…

Just be aware that states like ‘unknown’ or ‘unavailable’ will also cause the light to turn off.

#8

It’s ok in this case… but for my learning. How to remake it in this “sophisticated” way to work only when changing from home to not_home and vice versa? Condition with IF ELSE ?

Just add a condition to check if the tracker is one of the two valid states.

alias: PowerNotebook
trigger:
  platform: state
  entity_id: device_tracker.notebook
condition:
  condition: or
  conditions:
    - condition: state
      entity_id: device_tracker.notebook
      state: 'home'
    - condition: state
      entity_id: device_tracker.notebook
      state: 'not_home'
action:
  service_template: >
    {% if trigger.to_state.state == 'home' %}
      switch.turn_on
    {% else %}
      switch.turn_off
    {% endif %}
  entity_id: switch.63743864dc4f22d434c2

OK. Thank you.
