Hello I'm trying to use my smart plug in a no network condition. but I found out the schedule is not working. 
I'm thinking like the plug don't have battery of timing. So when I setup the schedule and unplug it and take it to where I'm gonna use it(the place that has no network), and plug in, the schedule is not working. 
 

does anyone has any idea on a good solution with my situation?

thank you!!
