Enable NUT on KSTAR Micropower 600VA

I have a KSTAR Micropower 600VA (USB identifies as MEC0003), installed NUT, did the following config:

Disable beep of KSTAR Powercom 600VA UPS (USB identifies as MEC0003)

But the deamon is not starting:

sudo service nut-server status

ups.conf:

maxretry = 5

MODE=none

[kstar]

driver = nutdrv_qx

port = auto

desc = "Description of this UPS"

Seems like I miss some configuration, can anybody please help? Thanks in advance, Sandor

As a first it doesn't seem like the mode is set properly. Start by editing nut.conf as follows:

$ sudo nano /etc/nut/nut.conf

Set the mode to standalone:

MODE=standalone

Also, remove the line MODE=none from your ups.conf!

When you're done with that you can try again with starting nut:

$ sudo upsdrvctl start

and

$ sudo systemctl start nut-server

Finally check to make sure everything works properly:

$ sudo systemctl status nut-server

You should see following:
