Configuring NUT add-on to connect to SNMP

In the past I have used RaspberryPIs to run NUT service for UPSs connected to the Pi via USB. Fot this I just needed the NUT Integration

Now I want to integrate an Eaton 5PX Gen2 UPS using SNMP. The 5PX has a network interface card

On the 5PX I have enabled SNMP v3 and setup a user with no auth, no priv authentication

My understanding is that I need to use the NUT add-in to interface with the SNMP service. I have installed the add-in but I am confused how to configure the device section. I tried added some config values (eg. snmp_version=v3) but when I start the addon, the logs complain that I have not set a username

Does anyone have an example of how to setup the device fields for and SNMP integration?

Thanks

Solved by using V2C SNMP service on the 5PX UPS which worked fine
