I'm incredibly new to all of this, but am hoping to add some simple alerts and need to know how.
How do I set a garage door to start a timer when open?
Then send an alert if it has been open for a certain amount of time (10 minutes, then 20, then 30).
But to reset and stop the timer once it is closed, so it doesn't keep sending alerts or break next time the garage opens.
Does this already exist, or do I need someone who understands using YAML?
Thank you in advance for helping me learn!
