NUT Issues With Rmcard205

Hello,

I am aware the NUT add-on needs to be first installed followed by the integration. What I am wondering is can you add a second UPS to be monitored, specifically one using ethernet via rmcard205? I have one UPS being monitored via USB and have had 2 in the past, but cannot seem to get the one running with rmcard205 to work. I have tried adjusting the nut add-on configuration using something similar to this

- name: RemoteUPS1
  driver: snmp-ups
  port: 10.2.3.4
  config:
    - desc: My remote UPS in the basement
    - ...

I guess the question I have is does NUT need to be installed to a device connected to the UPS and is this not do able over a network just using user name and password which the integration rejects each time I try.
