Turn the switch back ON after x minutes OFF

Hi Folks - I have no coding ability - wondering if anyone can fix the code here (Turn off Appliance Module for 30 minutes, then turn back on automatically) to make this request work. That smartapp won’t turn on the device after X minutes off. Looked everywhere and can find a tonne of off smartapps that do similar for things to go to the off state- just no back ON apps? There are a few folks like me been looking for such an app. Any help would be greatly appreciated

Thanks

PS - Happy New Year!
