Could there be possibly looked at to add UBNT Airmax devices? It seems LibreNMS picks them up as generic devices. The MIB files can be found here https://www.ui.com/downloads/firmwares/airos-ubnt-mib/ubnt-mib.zip
Works fine for us. You might try to make sure SNMP is setup on your devices and UBNT uses only V1 SNMP.
I really miss to see connected users with sgnals and traffic. And possibility to trace connected customers by mac to show where they are connected with stats. PLS ADDD
