I am in the process of planning out a home upgrade, which will include multiple UPS devices (server rack, media center, my desk, spouse's desk). Ideally, I'd like to keep an eye on all the UPS devices on a single dashboard that I am not paying a yearly fee for (thanks, APC), so I am looking to set up NUT on a Raspberry Pi, and have it monitor the UPS I currently have online, which will then manage my TrueNAS if there's a power outage.
At this time, I have the UPS online and configured, and the TrueNAS is attached by USB for now. Both devices are online via Ethernet as well - the UPS has an APC Network Management Card in it (not that SmartConnect portal they want you to pay for). I also have a Raspberry Pi 4 online, with NUT installed.
I've cross-posted this in several forums, but keep getting no response or bad information.
Where I am running into trouble is getting NUT to see / talk to the NMC in the UPS. The NMC is online, and I can query it from the Pi using snmpwalk. Details below:
(snip of rest of output, it's clear it's responding)
ups.conf:
What happens when I test this:
My guess is that I am missing something simple in the config, or there's a package I am missing in relation to SNMP. Any insight would be appreciated.
