"CMD list does not start with correct line. Unexpected line received 'ERR DRIVER-NOT-CONNECTED'."))

These seems to me that your UPS is not configured correctly with NUT. Does NUT seem them at all? What does your /etc/nut/ups.conf look like?

[sammcj]

Hey, yes both my UPS work in NUT:

[PSA]
  driver = usbhid-ups
  port = auto
  vendorid = 10AF*
  product = .*LiebertPSA.*

[CyberPower]
  driver = usbhid-ups
  port = auto
  serial = CTLLU2000129

[SuperioOne]

DRIVER-NOT-CONNECTED is an error reported by NUT service. It usually means the driver is misconfigured or not running.

At first glance, your ups.conf looks normal to me. Only possible issue is the 10AF* regexp part, but I think it should match with Liebert's vendorid (10AF) anyway.

All I can recommend for now is: double checking USB devices' serial codes and product names using lsusb -v command and verifying NUT service with upsc -L.

Hmm ok thanks for the advice, I appreciate that!
