I use a "fake" condition that's always true to enable an on and off in the same flow. In the attached the top part of the OR is IF there's motion AND it's after 12:01 am (duh) THEN turn my lights on. The bottom is IF motion has stopped AND it's after 12:01 am THEN turn the lights off.
I know I could (should?) probably use a variable always set to true instead of a time check, but I'm still new and haven't gotten into variables yet.
As long at everything is connected, you can keep adding IF/OR conditions. I have one flow that has five to turn on a light in the morning, turn it off of my wife leaves or turn it off at sunrise.
