Exposing HA code to Google Routines

Configuration
1

When I need to have Google Assistant so something on HA, I can create a script in HA, expose it to Google Assistant (synchronize). From there I open my Google Routine, Add an Acfion, Add a Scene and if I did everything correctly I should be able to see/select the exposed script.

Is it possible to expose automations? Can Google Routines trigger HA automations? Having to create a script to run an automation is a bit silly.

No.
What I would do is add a button or toggle entity exposed to Google, then add that entity as a trigger in your automation. turn on the entity, trigger the automation.

Generally turning automations on and off is a VERY bad practice anyway. That’s what scripts do. Automations have triggers to fire them.
