I observed that the script always wakes up my homeserver and tries to load a banner for an episode although I do not use those banners anywhere. This happens during the execution of the "Next Episodes" script which runs very slow on my system (Windows 8.1, Kodi 16 Beta 2, 61 TV Shows with ca. 2000 episodes, MySQL on Rasperry Pi). It takes up to 10 seconds before the widget Displays the next episodes.
Is there anything I can do? I do not want the homeserver to wake up every time I open the widget for the next episodes...

I looked at the code and this script is not doing that but the skin is.
A good widget implementation should have all widgets loaded in the background (with visibility) conditions.
This will prevent the widget from reloading every time and it will display instantly. Only on startup you'll have that 10 seconds loading time.
I think that will also fix your homeserver waking up all the time.
Please contact the skin developer because he/she can be at more help with this.

OK, will do. Thanks a lot!
