We have a HP R/T 3000 G4 UPS; according to the data returned by the usbhid-ups driver, it seems to be a "badge engineered" Eaton 5PX UPS LI R 3000.We have a stubborn "Replace Battery" alarm that stays despite: ... The panel doesn't show any battery-related alarm. I initially "guessed" this was some kind of stale flag in some internal NUT database or cache, but I couldn't find on the hard disk where that is/was, and restarting all NUT daemons & drivers didn't help either.
The upsd daemon keeps an image of the current state of the UPS unit in memory. There is no external database. The monitor daemon upsmon polls this image.
Anybody has a clue how I should proceed or debug the issue?
At first sight this looks like a "feature" of the particular UPS unit you have, but perhaps other have deeper insight.
