Who can help me with a automation for the following?
I have a door contact sensor (lets call it binary_sensor.door).
When the door is open for 5 minutes it must send a pushover notification that the door is still open. After 5 minutes it needs to check it again and also send notification again and repeat this until the door is closed.
If the door is closed within the first 5 minutes, there should not any notification being sent.
