The following is a quick guide on getting basic status LED functionality working with TrueNAS running on the UGREEN DXP4800 Plus. Theoretically, it should work on all models (with some small revisions to the script), but I only have a DXP4800 Plus. :)
This guide is for cron job that runs a script to update the LEDs every couple minutes, but I'm sure the following can be modified for blinky LEDs as well.
Sometimes I want to make a quick web search, and I’d prefer not to leave
Emacs. Sure, I could switch over to a different workspace and open a browser,
but I’d much rather do it in Emacs if possible. eww will let you search
instead of enter a URL, but you only get one search engine (which is, by
default, Duck Duck Go). I’m used to the wonderful interface of Chrome, which
allows you to use a keyword to specify your search engine, right within the
“Omnibox”. Anything else feels crude. So, I decided I would implement my own
search solution!
