I was trying to make the point that the 24.0 V reading is suspect, while covering the cases where broken scaling means that NUT displays it as 16.0 V. However, back in January, we discussed the input.transfer.high/.low issue: https://alioth-lists.debian.net/pipermail/nut-upsuser/2020-January/011668.html The root cause of that is closer to some of the other CPS issues, like the "output.voltage: 137.0" that Robert posted. That upsc dump is useful. For completeness, could you (and Robert) please post the output of "upsrw myups" and "upscmd -l myups"? I manually grep through upsc output to find these sorts of things, but some day, I'd like the DDL[*] to be able to show a table of UPS models and their supported NUT variables. (Something like a hardware comparison on a vendor website, but from the perspective of what NUT can read.)
