PVR backend with EPG that automatically updates?

I was hoping somebody could help me. I am looking to setup a Windows 10 backend that is able to be setup for my HDHomeruns with an EPG that will automatically update every couple nights without having to do anything on my own. Currently I created a .bat files that uses Zap2XML to download automatically every night from zap2it, but Next PVR still makes me go into the program and update it manually from the downloaded XML file.

Thank you in advance.
