Warn message every 10 minutes : Unexpected state type: StringType from LCN Binding

Nermpe · June 17, 2022, 6:26am

in my openHab log I get every 10 Minutes this message:
[cn.internal.converter.ValueConverter] - Unexpected state type: StringType
How do I find out what is the couse of this message?

This is certainly triggered by the LCN binding at this line:

github.com

openhab/openhab-addons/blob/da59cdd255a66275dd7ae11dd294fedca4942d30/bundles/org.openhab.binding.lcn/src/main/java/org/openhab/binding/lcn/internal/converter/ValueConverter.java#L116

      
        
                @Override
                public State onStateUpdateFromHandler(State state) {
                    State result = state;
            
            
        if (state instanceof DecimalType) {
                        Unit<?> localUnit = unit;
                        if (localUnit != null) {
                            result = QuantityType.valueOf(toHumanReadable(((DecimalType) state).longValue()), localUnit);
                        }
                    } else {
                        logger.warn("Unexpected state type: {}", state.getClass().getSimpleName());
                    }
            
            
        return result;
                }
            }

DecimalType is expected by the binding.

thank you for the replay,
What do I have to change where? I have almost 30 LCN Things and nearly 100 Items.

Lolodomo · June 17, 2022, 7:51am

I can’t really help more, I do not know this binding. But the binding maintainer would probably help you if he sees your topic. I would suggest to mention LCN binding in your topic title.

Nermpe · June 17, 2022, 7:53am

thankyou, done

fwolter · July 11, 2022, 6:31am

I didn’t see your question until now. You can give me a mention next time or add the “lcn” label. Are you still interested in a solution? I would extend the log message and send you an updated version of the binding, then.

Nermpe · July 11, 2022, 9:30am

Yes please. I still get this error message every 10 Minutes

Nermpe · July 21, 2022, 8:24am

@fwolter: did you see my replay?

fwolter · July 21, 2022, 8:31am

Yes, have it on my TODO list.

fwolter · September 22, 2022, 6:28pm

I improved the logging. The message should contain the module address, the variable and the actual value, now.

Give it a try: https://github.com/fwolter/openhab-addons/releases/download/lcn-improve-logging-1/org.openhab.binding.lcn-3.4.0-SNAPSHOT.jar

Nermpe · September 28, 2022, 11:47am

Could you please give me advise how to install this?

fwolter · September 28, 2022, 11:56am

Simply drop the JAR file into the addons folder of your OH installation. e.g. under /usr/share/openhab/addons.

Nermpe · September 28, 2022, 4:27pm

Thank you for the information.
The logging does not change I dont see any other or more Messages.
Looks like I do somethiong wrong

fwolter · September 28, 2022, 5:12pm

Maybe the currently installed LCN binding interferes with the new one. You can temporarily uninstall the LCN binding. Things and Items are left untouched.

If that doesn’t help, you could try to clean the cache by running openhab-cli clean-cache when OH is stopped.

Nermpe · September 28, 2022, 9:52pm

now I get a new Message:


 [inding.lcn.internal.LcnModuleHandler] - S000M070: RVARSETPOINT1: Value conversion failed: Unexpected state type: Was StringType but expected DecimalType: Not configured in LCN-PRO: RVARSETPOINT1

fwolter · September 29, 2022, 5:33am

You seem to have an Item linked to regulator 1 (R1Var) of the LCN module 70. When OH polls it, the LCN module responds, that R1Var is not enabled in LCN-PRO.
