Wake the device from sleep at a given time of day.

If you have a screen lock enabled this may interfere with the wake function, so please turn this off in Android Settings > Security.
Please note we use a background job which can take 15 minutes to execute (this is a standard Android feature to reduce battery consumption), if you have scheduled power on/off to occur at 13:00 please wait until 13:15.
