Growl or Snarl notifications

    I am used to using gntp-send on Linux boxes on my LAN to send messages to Growl running on my Windows PC. It would be kind of useful if I could somehow send messages from LibreELEC 5.10.95 running on a Raspberry Pi 4, e.g. to say that the device is online, has completed a task, etc. Is there any kind of addon or plugin that would allow some kind of messaging?

    In short, nothing exists. I'd guess because people are either sat in-front of the computer running Growl *or* sat in-front of the TV watching something on the HTPC device. We have no package manager in the OS so you can't just install it. However, if the gntp-send binary is simple you might be able to simply copy it over from, e.g. RaspiOS, but if not you'll need to find a docker container (overkill, but works) or self-build a custom LE image with the package added - there are rather deliberately no instructions for that kind of thing.

    I tried copying the binary, but it complains about not finding a shared library, libgrowl.so.0. I think I'll not worry too much. If I need to know if the HTPC goes on or off line I can whip up a Bash script running Nmap in WSL or one of my Linux boxes and run it with cron.
