Do I have to run the water pump for 24 hours?





How many water pumps should I set in setup-output and set in trigger (daily span) for 30 minutes after 1 hour of operation?
Or Do I have to run the water pump for 24 hours?

The setup you are showing will never turn the output off. You either need to specify a duration for the output to be on for or create a Time Point Trigger with an Action to turn off the output.
