I had a number of automations that started things like sprinklers and pool pumps. I am often messing with HA and wanted a fail safe to shut off something if it is left on by automation or manual activation. It is not elegant, but this is the flow I use to shut things off if they are left on. The flow continues to my email notification that I did not include in the example.
