Best way to trigger a periodic action when a state is "on" and survive server restart?

Configuration
1

Sorry if the title isn’t clear enough. Basically I want to build an automation that uses Gemini AI to detect if my 3D printer is printing spaghetti, like this.

The 3D printer integration (Moonraker) provides a state entity, on which I can create a trigger, and use wait_for_trigger with a timeout to perform a loop action that sends the image to Gemini and stop the print if necessary. However, the problem is that once HA restarts(which I sometimes do), the automation is interrupted.

May I ask for the best way to reliably run an action every 15 minutes regardless of HA restart. I guess it cannot be a loop in an automation.

Thanks!

My naive thought would be to create an automation with a trigger every 15mintues, but only enable it when the print starts. Not sure if there’s other better way.

Are you sure the AI will be correct during the first minutes of the print?

You might need to use a time pattern trigger and have the printer state as a condition instead
