SNMP Binding + APC PDU: "PDU doesn't contain a variable with OID"

Add-ons Bindings

I’m currently trying to control an APC PDU with OpenHAB2 using SNMP.

Switching the Outlet does work, however fetching the current State of it is not.
I’m not sure if I am doing something wrong or the binding is just broken.

Debug log:

17:34:45.064 [DEBUG] [hab.binding.snmp.internal.SnmpBinding] - SNMP: Send PDU 192.168.*.*/161 GET[requestID=0, errorStatus=Success(0), errorIndex=0, VBS[1.3.6.1.4.1.318.1.1.4.4.2.1.3.8 = Null]]

Item Configuration

Switch Switch_Foo  "Test Switch  [%s]"  { snmp="<[192.168.*.*:public:1.3.6.1.4.1.318.1.1.4.4.2.1.3.8:10000:MAP(APCPDUOutletState.map)] >[OFF:192.168.*.*:private:.1.3.6.1.4.1.318.1.1.4.4.2.1.3.8:2] >[ON:192.168.*.*:private:.1.3.6.1.4.1.318.1.1.4.4.2.1.3.8:1]" }
String Uptime "Uptime [%s]" {snmp="<[192.168.*.*:public:1.3.6.1.2.1.1.3.0:10000]"}

Querying the OID using snmpget works as you would expect it:

snmpget -v1 -c private 192.168.*.* 1.3.6.1.2.1.1.3.0
iso.3.6.1.2.1.1.3.0 = Timeticks: (2941180) 8:10:11.80

snmpget -v1 -c private 192.168.*.* 1.3.6.1.4.1.318.1.1.4.4.2.1.3.8
iso.3.6.1.4.1.318.1.1.4.4.2.1.3.8 = INTEGER: 2

Any Ideas?

The log message is misleading since it always appears if there is more than one item with different OIDs but the same IP.

Fetching the values works with a jar built from the latest git source. No idea why.

Hi, on openhab 2.3 i have been using the below snmp binding detail, I notice you are missing the leading . from your item

String Switch_AName "Name[ %s ]" {snmp="<[10.0.0.103:private:.1.3.6.1.2.1.1.5.0:10000]"}

Your item definition, missing a “.”

String Uptime "Uptime [%s]" {snmp="<[192.168.*.*:public:1.3.6.1.2.1.1.3.0:10000]"}
