So... 50% load +/- 10% :-) (The use of the term "calibration" for an UPS is slightly unfortunate - it's certainly not a traceable metrology-style calibration. I would not be surprised if most of the passives were 5-10% tolerance, and not temperature compensated.) > I have the snmp-ups driver working with it, have not enabled upsmon yet, > but upsc seems to get a rather limited set of data from it: ... > In particular, no load, no input or output voltage.

I forgot that this landed after 2.7.4: https://github.com/networkupstools/nut/pull/632/commits/3f5e3728a720aba0be76b2fccb603b04962bb904 <https://github.com/networkupstools/nut/pull/632/commits/3f5e3728a720aba0be76b2fccb603b04962bb904> I forget, is your copy of NUT built from an RPM? If so, it shouldn't be too hard to add that patch to get load, charge, input voltage/frequency and output voltage (assuming the RM205 is a superset of the RM202). You can also use snmpwalk to see what other values might be available. Since there is already a skeleton MIB mapping in NUT, the only two things needed are probably the snmpwalk outputs described at the end of this section: https://networkupstools.org/docs/developer-guide.chunked/ar01s04.html#snmp-subdrivers <https://networkupstools.org/docs/developer-guide.chunked/ar01s04.html#snmp-subdrivers> > (Also, I can so far connect only using snmpv1, but I don't know whether > I should expect to get any additional data from snmpv3 anyway.) Again, not my area of expertise, but as far as NUT is concerned, I think the different versions are for authentication methods (SNMPv1 is cleartext).
