We have deployed a large number of Conteg Smart PDUs (Model: IP-SEA-318C36C9POM32) and they are currently detected as “Generic Device”. I have attempted to add support via Custom YAML, but the sensors were not discovered correctly due to the specific indexing of the Conteg Databus MIB.

We require official support to monitor power metrics (Voltage, Current, kWh) and environmental sensors.

Technical Details:

  • Manufacturer: Conteg

  • Model: IP-SEA-318C36C9POM32

  • SysObjectID: .1.3.6.1.4.1.28402.12.1.1.2

  • Data Scaling: Most metrics (Amps, Volts, Temp) use Centi-units and require a divisor of 100.

Debug Information:

- MIB: https://gist.github.com/6576974775d781b0f592d326938a901f

- Discovery: https://paste.rs/9YVaK

- Poller: https://paste.rs/ExHEh

- SNMP Walk: conteg_walk.txt · GitHub

Thank you for your assistance in integrating this device into the LibreNMS core.

Try this patch.

Temperature sensors had no data in the walk.

could you supply a snmpwalk without the OID at the end.

Hello @sandap1,

First of all, sorry for the delayed response.

Regarding the full snmpwalk: I have tried multiple times to perform a walk starting from the root (.), but unfortunately, the Conteg PDU units are very sensitive to large SNMP requests and keep timing out, even with increased timeout settings and retries.

However, the walk I previously provided (https://gist.github.com/CCAA79/20a83ba23f0fc4a84d940aa3b3c59d2d) is a complete walk of the .28402 tree, which contains all the device-specific sensor data.

To assist with the identification, here is the standard system info:

  • sysObjectID.0: .1.3.6.1.4.1.28402.12.1.1.2

  • sysDescr.0: Conteg Databus Device

Regarding Temperature sensors: These units have internal sensors that show values in the Web UI. However, no external probes were connected during the walk, which is why those specific OIDs returned no data or zero values.

I hope this information is sufficient to merge the patch. Please let me know if you need me to query any specific OID individually!

Hello @sandap1,

I have just finished testing the patch with ./scripts/github-apply 18811 and I am happy to report that everything is working perfectly!

The device is now fully recognized with the Conteg logo, and all sensors (Voltage, Current, Power) are reporting highly accurate values. The scaling is exactly as it should be. I am now waiting to collect enough data points over the next few hours to ensure that the graphs are also generating correctly, but so far everything looks great.

We would like to thank you very much for your immediate help and the excellent work you did on this. It is much appreciated!

The PR is 100% ready from my side. Looking forward to the merge!
