Hi, I’m trying to migrate from OH2.4 to OH3.1 with a clean install.

I’ve installed the SNMP binding, but I’m unable to setup a Thing in Paper UI. When I try to do that the Status label is “UNKNOWN” and nothing shows up on the TRACE log.

The SNMP was working fine in my old OH2.4. Any ideas?

Please show the thing configuration.

UID: snmp:target:4a49913814
label: SNMP Target
thingTypeUID: snmp:target
  retries: 1
  protocol: v2c
  port: 2600
  refresh: 60
  community: public
  timeout: 5500

It’s also strange that the log only shows this INFO (no ERROR on UNKNOWN status):

2021-09-20 18:52:03.595 [INFO ] [ab.event.ThingStatusInfoChangedEvent] - Thing 'snmp:target:4a49913814' changed from UNINITIALIZED (DISABLED) to INITIALIZING
2021-09-20 18:52:03.610 [INFO ] [ab.event.ThingStatusInfoChangedEvent] - Thing 'snmp:target:4a49913814' changed from INITIALIZING to UNKNOWN

Did you add a channel? It seem that no channel is present. Without a channel, no refresh is initiated and the thing stays in UNKNOWN state.

Thanks for the help! The UNKNOWN label was throwing me off.
