core: Unexpected service call check for automation that has not been triggered.

The problem

After creating an automation from a blueprint (https://community.home-assistant.io/t/synchronize-the-on-off-state-of-2-entities/259010) the resulting automation is generating a Repair notification for an unknown service call, even if the automation has not triggered. Repair error: Last triggered automation:

I’m writing this issue to highlight that behaviour, as it seems that the service call should not be checked if the automation has not been triggered.

Reason for the error under normal circumstances: The automation has a service call homeassistant.turn_{{trigger.to_state.state}} and the problem is that if one of the entities is ‘unavailable’ then that state is passed through to the action and a service call of homeassistant.turn_unavailable is detected. This is an unknown service, hence the error and Repair notification: The automation "Synchronize states" (automation.synchronize_states) has an action that calls an unknown service: homeassistant.turn_unavailable

Problem with this error/Repair notification: There is nothing in System>Logs identifying this error (I’ve included the error from home-assistant.log.1 below). The Repair notification can be cleared by clicking submit but when HA restarts, the Repair notification/error reappears at the top of the settings page, even though the automation has not triggered and there is no trace showing the ‘unavailable’ state being passed through to the service call.

Other users have experienced this behaviour, as documented in the blueprint topic, copied above, and in this topic - https://community.home-assistant.io/t/unexpected-service-call-check-for-automation-that-has-not-triggered/458257

Example YAML snippet

blueprint:
  name: Synchronize states
  description: Synchronize the on/off state of 2 entities
  domain: automation
  input:
    entity_1:
      name: First entity
      selector:
        entity: {}
    entity_2:
      name: Second entity
      selector:
        entity: {}
  source_url: https://community.home-assistant.io/t/synchronize-the-on-off-state-of-2-entities/259010
mode: restart
max_exceeded: silent
variables:
  entity_1: !input entity_1
  entity_2: !input entity_2
trigger:
- platform: state
  entity_id: !input entity_1
- platform: state
  entity_id: !input entity_2
condition:
- condition: template
  value_template: '{{ states(entity_1) != states(entity_2) }}'
action:
- service: homeassistant.turn_{{ trigger.to_state.state }}
  data:
    entity_id: '{% if trigger.from_state.entity_id == entity_1 %} {{ entity_2 }} {%
      else %} {{ entity_1 }} {% endif %}'

Anything in the logs that might be useful for us?

The automation "Synchronize states" (automation.synchronize_states) has an action that calls an unknown service: homeassistant.turn_unavailable.

This error prevents the automation from running correctly. Maybe this service is no longer available, or perhaps a typo caused it.

To fix this error, edit the automation and remove the action that calls this service.

Additional information

I can confirm that rewriting the automation, without using the blueprint, stops this behaviour. I decided to raise the issue though as others are experiencing the same behaviour and it is information for you to consider regarding blueprint generated automations.
