I'd say the killpower flag file sounds most suspicious for this role. In some distros it may be in /etc and there was an init-script to delete it early in boot.Regarding the "pile of ASNs", I wonder if David could (get someone to) produce a custom MIB mapping source for https://github.com/networkupstools/nut/blob/master/drivers/snmp-ups.c#R92 to integrate with Tripplite's over SNMP better than via IETF default tables...Jim

 The pile of unhandled ASNs is what had me worried about relying on the SNMP connection in the first place...

Ah, you're referring to the WEBCARDLX firmware (i.e. the management card installed in the UPS). There's also a UPS firmware that isn't generally updated in the field I thought you were referring to (that displays on the LCD and is reported via the WEBCARDLX  too, probably ends in 16 on that unit).
That firmware should have no impact on this issue, but thank you for clarifying!

We should get a support ticket open for you like we did with another user. Can you shoot me a direct email (off-list) with your contact information (shipping address and contact number)? I do plan to give the mailing list an update when/if I get to root cause,  but I don't have that yet. In the interim, I'd like to see what we can do for you (or anyone else that runs into this... strangely it does not occur on most/all units).

> Is there any hope for using it over SNMP with NUT instead?

It should work. The WEBCARDLX supports the RFC1628 "UPS MIB" and that is what the ITEF driver uses. Generally, our support for  the RFC1628  MIB works in all recent versions.
I can set up some tests later this week or early next week to demonstrate, but feel free to shoot over the specifics of the errors you see and your config if you'd like.

Thank you,
