Can I set this to come on at a certain time and go off. Like 9pm on then off at 6sm?

Hello Larry, thank you for your question. For what you are wanting to do we would recommend item 41431 because you can set up 2 custom on off times. Here is the link. https://www.lowes.com/pd/myTouchSmart-myTouchSmart-24Hr-In-Wall-Digital-Timer-with-On-Off-Door/5001067087
