It takes a while for anything to reload on my poor rPi3 so I use the automation_reloaded event to send a toast notification to the UI so I know when I can test my changes. I’m left guessing when scripts, groups or anything else has actually reloaded.
I just ran into this need with the new “reload template” ability… I have an automation that triggers after reloading my template sensors… it has a condition to prevent it from firing after a restart… but that doesn’t work when I “reload template sensors” it would be nice to have an event that could be monitored so if it was a manual reload it doesn’t fire the automatons…
