The schedule configuration is saved on the device itself, so it can function without internet.

So to turn on the plug itself without internet, you can setup a schedule in advance with the following instruction:

Meanwhile, there will be a new feature called smart action will be added in the near future, you can give it a go after that. 

@Pappas Be careful with this feature.  If there's a power outage the HS100 comes back up OFF.  Your router won't be started, and none of the scheduled commands will run as the HS100 won't be able to find the current time from the network (it requires NTP access to run timers).  You won't have any access to restart your router until you're home to do it physically.
