[SOLVED] BACnet Binding errors "Could not set read property [FAILED toString()]"

The BACnet Binding works but i´m getting the following stack trace errors:

What is you item definition. Did you add a unit to the item?

Number Outside_Temperature "Aussentemperatur" <temperature> ["CurrentTemperature"] {bacnet="device=1337,type=analogInput,id=3"}
Number Outside_Humidity "Feuchtigkeit" <temperature> {bacnet="device=1337,type=analogInput,id=4"}
Number Regenmelder "Regenmelder" {bacnet="device=1337,type=binaryInput,id=1"}


//Niveau
Number Zisterne_Fuellstand "Zisterne Fuellstand" {bacnet="device=1337,type=analogInput,id=8"}
Number Zisterne_Sensor_Winkel "Zisterne Sensor Winkel" {bacnet="device=1337,type=analogInput,id=9"}

Number Zisterne_Sensor_Stoerung "Stoerung Niveausensor" {bacnet="device=1337,type=binaryInput,id=3"}

//Gartenventile

Number Garten_Wasserventil_2 "Bewaesserung Ventil 2" {bacnet="device=1337,type=binaryOutput,id=2"}

//Heizung

////Wohnzimmer
Number Wohnzimmer_Temperatur_Xi_BACnet "Wohnzimmer Temperatur Xi" {bacnet="device=1337,type=AnalogInput,id=5"}

Did this happen recently after an update?

on every change

No I mean after updating openHAB?

No I only restarted the Pi and it’s only by items I use on HABPanel

Put the bacnet binding in debug mode and publish the log, please

@splatch
Hi Lukasz, Do you still look after this binding?
Can you help, here?

Hey, thanks for pulling me into topic. I do maintain 1.x integration. From stack trace I can’t clearly say what happens - possibly property identifier is malformed (not an int for some reason) causing in the end null pointer.

I see you are using version from January. I just released 1.12.0. It is the same code as previous release, but to be on safe side please update and then we will track issue.

Hopefully I will be back on openhab related topics in few weeks and will sort most annoying issues for 1.x line.

After an upgrade from OH 2.2 to 2.3 no more errors…
