I have an automation that notifies on my home speakers that the laundry is done.
I want to add a reminder, so if after 20 minutes the washing machine's door hasn't been open, it notifies me again. (Important, waiting 20 minutes and checking if the door is open is not correct. It needs to show only if the door never been been open in the last 20 minutes)
I don't see an easy way yo achieve that
