Discovery doesn't work on my CS141 ups card. It works on my cs121 cards though. I checked sysobjectid and the output is "The Cs141 SNMP Agent". After changing "CS141" to "Cs141" in generex-ups.yaml the discovery worked fine.

Thanks for the fix. Now it does discover properly but polling is no go.

"Checking (snmp) current Output Phase 1..."
. = No Such Instance currently exists at this OID
Should be: . = INTEGER: 104

The Generex support was contacted and I've got a confirmation that's a firmware problem that will be solved in the future 1.50 release planned in two weeks.

Ignore the above. This still needs fixing.

Generex has released the 1.50 firmware, including the fix (not tested at this time):

  • Bugfix: SNMP-Agent appends wrong “.0" to OIDs of tabular values [#3341]

Discovery and polling works fine after 1.50 fw upgrade
