Can't make an alert checker to match input voltage in an APC UPS

My goal is to get the input voltage and know when the AC input is off.

I have an alert checker that matches with others UPS using "sensor description">match>"input" but with this APC UPS in particular, it doesn't work. Looking into the voltage graph found this:

Which is different from the other UPS:

I tried to match "Sensor Text OID" (PowerNet-MIB::[upsHighPrecInputLineVoltage|https://mibs.observium.org/mib/PowerNet-MIB/#upsHighPrecInputLineVoltage].0), "Sensor Numerical OID" (.1.3.6.1.4.1.318.1.1.1.3.3.1.0) and "Sensor MIB" whit both values without luck.

If I run the smptget with that OID, i get the right value:

observium@nms:~$ snmpget -v2c -c xxxx ups-apc.dc.xxxxx .1.3.6.1.4.1.318.1.1.1.3.3.1.0
iso.3.6.1.4.1.318.1.1.1.3.3.1.0 = Gauge32: 2227

Also I tried to make an Custom OID alert checker instead of Sensor, and it also dowsn't work.

Any ideas? Thanks in advance!
