SNMP debug?

Configuration
1

I set up the following SNMP sensor, that is getting “unknown” as result.

- platform: snmp
  name: 'ars_uptime'
  host: 192.168.1.253
  community: public
  baseoid: 1.3.6.1.2.1.1.3.0
  accept_errors: true
  scan_interval: 60

Same sensor checking another host is working fine.

With an SNMP tester I verified, that 192.168.1.253 is responding correctly:

----------------------- New Test -----------------------
Paessler SNMP Tester - 20.2.4 Computername: HAL2019 Interface: (192.168.56.1, 192.168.1.111)

13.01.2021 14:20:59 (19 ms) : SNMP Datatype: ASN_TIMETICKS
13.01.2021 14:20:59 (24 ms) : -------
13.01.2021 14:20:59 (26 ms) : Value: 4569059
13.01.2021 14:20:59 (29 ms) : Done

Which log do I have to check to see what is failing?

Got it. Had to use the IP of the host’s virtual bridge network interface.
