Sensors gone after upgrading Ubiquti / Unifi switches to firmware 4.0.14.9736

Hi!

After upgrading my Ubiquiti switches to firmware 4.0.14.9736 I lost some sensors in LibreNMS. Previous firmware was 3.9.54.9373 and was able to display multiple temperature sensors and CPU usage. Please note the output from LibreNMS webgui log below.

Release notes from 4.0.14.3976: https://community.ubnt.com/t5/UniFi-Updates-Blog/FIRMWARE-4-0-14-9736-for-UAP-USW-has-been-released-Stable/ba-p/2610088

Any thoughts? Thanks!

In the upgrade, ubiquiti removed the sensors from the oids we ask for. I think someone was working on searching the new oids.

Thanks for the update Doc.

Would be great to see if the values are still there with other oids. Let me know if I could provide any further details. Maybe I could start a thread at the Ubiquiti forum as well (if there’s not already a thread about it).
