SNMP - Error while setting up platform snmp

Configuration
1

Hi - having some trouble with my SNMP configuration.

Sample Config:

  - platform: snmp
    host: 192.168.0.###
    community: <secret>
    baseoid: 3.6.1.4.1.12325.1.1.2.1.1

baseoid is confirmed working.

I’m receiving the data and it seems to be working fine but not sure what is creating the error. I’m a HA enthusiast, not really a developer so can’t tell from the error log below.

I’ve been researching a bit and it looks similar to this older, closed issue but not sure.

Thoughts?
Thanks!

Error text from HA:

Are you sure your Oid shouldn’t start with 1, I.e. 1.3.6.1.4.1.12325.1.1.2.1.1

Did anyone manage to figure this out?

Hi yes. You need the full base lid from the snmpwalk. Start with a period as I recall. I’ll double check when I’m back at my pc.

Update: Here is my config for pfsense wan in:

- platform: snmp
  name: wan_in_gb
  host: 192.168.###.###
  community: <secret>
  baseoid: .1.3.6.1.2.1.2.2.1.10.4

Hope that helps!

Edit 2:
If you are including a 64 bit counter, you need to include the version. This is clearly specified on the snmp sensor page however I missed it the first time. I hope it helps you.

- platform: snmp
  name: wan_in_gb
  host: 192.168.###.###
  community: <secret>
  baseoid: .1.3.6.1.2.1.31.1.1.1.6.4
  version: 2c
  value_template: '{{ ((states.sensor.wan_in_gb.state | float ) / 1000000000 ) | round(3) }}'
  unit_of_measurement: 'Gb'
