How do I get TVHeadEnd to read the zap2xml schedule?

[DarkKaplah]

Ok, I've posted this question a few places and everyone says to use schedules direct. I have used zap2xml.pl with NextPVR successfully so when trying to setup a LibreElec box with Tvheadend I used your implementation. For the life of me I can't get the last step working. I've:

1. Successfully installed your product from a zip (By the way, update your instructions for Kodi 17.3. I had to fumble to find the "Install from Zip" in this version).
2. Set up TvHeadEnd 4.0 under the http configuration to use Zap2xml.
3. Verified that I am downloading the schedule via ssh. The http.gz files appear after running an update.
   4)... How the heck do I get the schedule to show up? The channels are all set to "Auto EPG". When I deselect this I can't find a source to update from. Using the TvHeadEnd 4.0 "configure add-on" in kodi I have the ability to set a xmltv source but I have no idea where you're generating it.

You really need instructions to fill in this gap. BTW I'm not using TvHeadEnd 4.2 as I could get it working on a RPi 1, but not on the RPi3. It wouldn't talk to my HDHomerun Connect. So if this is a version issue I'm going to just stop here.

Schedules direct is easier but costs so we gotta suffer some.
You might want to follow the fork by edit4ever. I only update this when I feel the need. Setting up TVHeadEnd is kinda a PIA. There is information out there but it may not match exactly what you or I are doing, here are some links.

Check to see if you are getting the xmltv.xml file, that's the input to to TVHeadEnd.
I'm using TVHeadEnd 3.9 and RPi 2(I think).
In my notes I have:
You have the TVHeadEnd server installed and in the RPi configuration set the source to FILE and
set the full path/xmltv.xml in the next setting.
You have to fill in the EPG source in HTPS client under configuration>channel/EPG
(the web access IP of the RPi:9981,e.g. 192.168.1.xxx:9981)
Sorry,I don't have a good step by step but each situation is different, tuner, platform etc.

I don't know if DarkKaplah got this worked out already or not but just in case I'll say what I did.

I'm using tvh 4.1 (been meaning to update to 4.2.2 but it should be the same).

First, you need the actual "tv_grab_file", which you can find here.

Second, you need to have it at /usr/bin/tv_grab_file or a symlink setup so tvheadend can pick it up. In my case I have that script residing in tvheadend config directory, so I setup a symlink at /usr/bin/tv_grab_file to point to it because that's where tvheadend needs it. As I said before you can move the script itself there as well, but make sure permissions & ownership are correct.

Third, you need to edit the "tv_grab_file" script to your xml file. Edit line 7, which starts with "cat" and after that put in the path to your xml file, such as:
cat /epg/zap2xmlpy/xmltv.xml
The original line looks like this for reference:
cat ~/.xmltv/tv_grab_file.xmltv

For this next step you might have to restart tvheadend first but I don't recall... if you don't see this option then restart and then set it up.

Fourth and finally, go into tvheadend configuration > channel / epg > epg grabber
Under "Internal Grabber" you can set the cron if you want (for when tvheadend refreshes the xml epg file) but you do need to select "Module: XMLTV: tv_grab_file is a simple..."
Uncheck EVERYTHING below this, including the external XMLTV module.
