Description
We have a Schneider Electric BCEF0401A chiller of which the information is not shown correctly in observium.
We received a mib from our supplier, but there already seems to be a newer version in the observium mibs that is not attached to the chiller's OS or gets wrongly discovered.
(/opt/observium/mibs/carel/CAREL-bce-bcwc-MIB)
Can you please add support for this chiller So all information is shown correctly?
Thanks

I'm uncertain what you mean.
Can we schedule a zoom call to discuss & debug this together?

Also your attached mib seems as unrelated with snmpdump. No one snmp value is connected with clear variable.
I just cant understand which values what mean...

This is mostly derp MIB and os (for monitoring).
This units not report any hardware/vendor unique values, MIBs is vendor/hardware specific.
We not found ways for detect correct MIB files for specific models.
This looks like a job for the undocumented "static" sensors ability.
We have problems with devices that have undefined/one-off SNMP layouts, but those can just be manually added using the static sensors.
These Carel controllers all have broken/unusable MIBs, and it's even worse when they're in Schneider devices, because they care even less about keeping the SNMP functional.
The only realistic way to use these devices is to manually define each sensor in config.php so that Observium can use it. To do that you'll need to reverse engineer the OIDs to figure out which ones are the datapoints you want (or somehow get a mapping file from Schneider, it might be called a DDT).
static sensors are defined like this. it's straightforward, but time consuming:
$config['sensors']['static'][] = ['device_id' => '798', 'class' => 'load', 'oid' => '1.3.6.1.4.1.49314.1.1.1.4.9.1', 'descr' => 'Supply Fan A1', 'multiplier' => 1];
$config['sensors']['static'][] = ['device_id' => '798', 'class' => 'temperature', 'oid' => '1.3.6.1.4.1.49314.1.1.1.4.9.17', 'descr' => 'External A1', 'multiplier' => 0.1];
