Choose queued mode when an automation should finish each accepted run in order. Consider restart when the newest trigger should replace the previous run.
Set up the test
Use a harmless lamp or test notification. Create a delay so the first run is still active when you trigger a second time. Record the trigger times and use the automation traces to check which actions actually ran.
Interpret the result
Run the same sequence with one mode change. Queued waits for earlier accepted runs; restart stops the previous run and starts a new one if the conditions are met. Keep the actions and trigger gap unchanged so the comparison reflects the mode.
Worked example
A lamp that should remain on until the latest motion delay ends is a different task from announcements that should play in sequence. Avoid testing on locks, heaters or other safety-sensitive devices.
