I installed a new UPS today and after several failed attempts with other
software, installed Nut version 2.8 on my Centos 7 server using yum nut.
Several issues followed:
1. When I started nut-server it failed because /run/nut did not exist so
I created it by hand.
2. nut-server then started but gave he following in /var/log/messages:
May 11 13:33:00 mustang systemd: Started Network UPS Tools - power
devices information server.
May 11 13:33:00 mustang nut-server: fopen /run/nut/upsd.pid: No such

After a bit of manual tweeking, I now get:

3. I then tried upsdrvctl start but got:
[root@mustang ups]# upsdrvctl start
Network UPS Tools - UPS driver controller 2.8.0
Network UPS Tools - Generic Q* USB/Serial driver 0.32 (2.8.0)
USB communication driver (libusb 0.1) 0.43
No supported devices found. Please check your device availability with
'lsusb'
and make sure you have an up-to-date version of NUT. If this does not help,
try running the driver with at least 'subdriver', 'vendorid' and 'productid'
options specified. Please refer to the man page for details about these
options
(man 8 nutdrv_qx).
4. [root@mustang ups]# pwrstat -status
The UPS information shows as following:
Current UPS status:
State........................ Lost Communication
My ups.config has:
[nutdev1]
driver = "nutdrv_qx"
port = auto
vendorid = 0001
productid = 0000
bus = 002
protocol = hunnox
subdriver = hunnox
The UPS is Digitech 650va

It looks as if I am still missing something but I can't see what.
Cheers and thanks,
