This sent me down a rabbit hole since it’s something I’ve half-considering for a while. I prefer text configuration rather than GUI so I ended up installing graph-easy on my debian laptop:
sudo apt install libgraph-easy-perl
and made a first attempt to diagram the power setup in my campervan
It’s a perl module but the graph-easy
wrapper makes it behave like any other CLI tool. cat or echo the config text to the wrapper and the graph pops out on STDOUT
I use my Pi 4B as a DVR for movies and OTA television (MythTV).
There are other tools that handle playback better (OSMC/Kodi, etc) but Myth’s configuration and handling of recording schedules is incredibly powerful. Conflict management works well and it can record multiple streams off the same tuner so conflicts are reduced in the first place.
