[Observium] How to add support of new sensors for new (unknow) device

Hello!

I am very interested in adding support of new device series to Observium - NetPing (www.netping.ru) - devices for monitoring server rooms and remote power management.

Could you please suggest how can I add support of the sensors for unknown (for Observium) devices?​

I have access to​ SMNP MIBs of this divices and can read value of any sensors via SNMP. For example I know the OID to read the temperature from one of the sensons: .1.3.6.1.4.1.25728.8800.1.1.2.1 Could you please explain how can I show this temperature on a graph in Observium?

​Thank you.​
