Great question, Aaron! In the SmartThings App, you are able to create an automation for the Smart Plug to turn on/off at sunrise/sunset or a set number of minutes before or after sunrise/sunset. You can learn more about creating automations on our Support page here -- https://support.smartthings.com/hc/en-us/articles/115002056383. If we can assist in any way, please reach out to our dedicated SmartThings team at 1-866-813-2404 or support@smartthings.com. Thank you! ~Samsung Brand Ambassador
