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.
- Manually build or download the
ugreen_leds_clitool from https://github.com/miskcoo/ugreen_dx4600_leds_controller. - Plop it somewhere on your NAS (E.g. a dataset).
- In the same dataset, create your
.shscript that controls the LEDs. At the bottom of this gist is my modified version of meyergru's. - Make the script executable:
chmod +X your-script.sh.- You may also need to make
ugreen_leds_cliexecutable as well.
- You may also need to make
- In TrueNas, navigate over to
System Settings→Advanced - Under
Init/Shutdown ScriptsCreate the following to load thei2c-devmodule on boot:- Description:
Enable i2c-dev - Type:
Command - Command:
modprobe i2c-dev - When:
Pre Init
- Description:
- Under
Cron Jobswe then create a task to run every x minutes:- Description:
Update Status LEDS - Command:
/mnt/path/to/your/script.sh - Run as User:
root - Schedule:
*/5 * * * *(or however often you desire)
- Description:
- Reboot and wait a bit for your cron job to run.

thanks for the code, it works like a charm !!
btw, for guys who want to place the file in the boot-ssd (the OS drive)
just place the files (which are 'your-script.sh' and 'ugreen_leds_cli') inside "/root/" directory. Then chmod these files to 755.
(IDK why the chmod -X via terminal is not working, just typing 755 instead)
