AddOn??? I, for example, can't find it. The page is unavailable at the link.
If you look on the left menu is there, updated link https://wiki.libreelec.tv/installation/add-ons
Aha, now I've got a light bulb moment.
I needed that kick. Thanks! 
I've just installed the add-on. Can you please help me figure out what I should set so that my EPG refreshes every 6 days?
