Add wait_for_condition or allow wait_for_trigger to continue if the state has already been reached

[mendess]

When writing scripts I find myself writing the pattern

  - if:
    - condition: state
      entity_id: entity.foo
      state:
      - 'off'
    then:
    - wait_for_trigger:
      - trigger: state
        entity_id:
        - entity.foo
        from:
        to:
        - 'on'
      timeout:
        hours: 0
        minutes: 5
        seconds: 0
        milliseconds: 0
      continue_on_timeout: false

This is because wait for trigger will block if the state is already 'on' so I have to guard against that. Writing this is quite verbose and repetitive in the visual editor.

I think having a setting like continue_if_state_matches (or a better name) on wait for trigger would help. Alternatively a new block called wait_for_condition would also work.

This can be worked around using wait_template but that implies writing a template which goes against home assistant's goal of not requiring templates

FYI, if you're using this alot, you can make a script that does this and wait for it.

wait_for_state:
  mode: parallel
  max: 100
  sequence:
  - if: "{{ not is_state(entity, target_state) }}"
    then:
    - wait_for_trigger:
      - trigger: template
        value_template: "{{ is_state(entity, target_state) }}"
      timeout:
        hours: 0
        minutes: 5
        seconds: 0
        milliseconds: 0
      continue_on_timeout: false

Then just use the scripts service name to wait for the script to complete

- action: script.wait_for_state
  data:
    entity: entity.foo
    target_state: "on"

Yes, I'm aware that this is possible. I would have to create two scripts (or a more complex one) if I need to wait on an attribute change instead. I personally prefer writing wait_template to work around this. Technically the if/wait approach has a race condition if the state changes between the if and the wait. My suggestion is more to help improve HASS and not because I'm blocked from doing something
