I have OPNsense 25.1.7 running on some Qotom hardware.
Connected an APC SMVV750 (https://www.se.com/au/en/product/SMV750CAI/apc-easy-ups-1-ph-line-interactive-750va-tower-230v-6-iec-c13-outlets-avr-dry-contact-lcd-without-network-card-support/?range=65934-easy-ups&node=27590329547-easy-ups&selectedNodeId=27590329547) via supplied USB cable.
Added the Apcupsd plugin.
Configured - as per snip.
Can't seem to get anything other than "COMMLOST" for a status
Went to terminal.
Weirdly - when I run a usbvonfig list, <APC by S.E. SMV750CAI> at usbus0 only shows up sometimes.
