Ok, so you are getting home temp from the binding as number already transofrmed and then you are trying to transform it again in the rule.
Create this item:
String JsonString { mqtt="<[mosquitto:application/2/node/0000000000000013/rx:state:default" }
Add a space it the {} of the home_temp item just in case. It helps sometimes. And remove the tag. And comment out the binding temporarily.
Number home_temp "Living Room [%.1f °C]" <temperature> //{ mqtt="<[mosquitto:application/2/node/0000000000000013/rx:state:JSONPATH($.object.adc)]" }
Then change the rule to:
rule "Parse Room Temperature_1"
when
Item jsonString received update
then
val tem = transform("JSONPATH", "$.Object.adc", home_temp)
logInfo("TEST", tem.toString)
home_temp.postUpdate(tem)
end
I have done it like you said…
rule "Parse Room Temperature_1"
when
Item JsonString received update
then
logInfo("TEST", "running")
logInfo("TEST1", JsonString)
val tem = transform("JSONPATH","$.object.adc",JsonString)
logInfo("TEST", tem)
home_temp.postUpdate(tem)
end
That’s the rules file
Number home_temp "Living Room [%.1f °C]" <temperature>
String JsonString {mqtt="<[mosquitto:application/2/node/0000000000000013/rx:state:default]"}
That’s the items file

Thts log . I’n not sure what causes these errors… any help…
Try that:
rule "Parse Room Temperature_1"
when
Item JsonString received update
then
logInfo("TEST", "running")
logInfo("TEST1", JsonString.toString)
val tem = transform("JSONPATH", "$.object.adc", JsonString.toString)
logInfo("TEST", tem)
home_temp.postUpdate(tem)
end

I suppose i need to convert it into a decimal type… because it’s not updating in openhab… is there any command to do that?
Again. use .toString
rule "Parse Room Temperature_1"
when
Item JsonString received update
then
logInfo("TEST", "running")
logInfo("TEST1", JsonString.toString)
val tem = transform("JSONPATH", "$.object.adc", JsonString.toString)
logInfo("TEST", tem)
home_temp.postUpdate(tem.toString)
end
But now that we have established that
- mqtt works
- binding syntax is correct
You can try this directly and bypass the rule:
Number home_temp "Living Room [%.1f °C]" <temperature> {mqtt="<[mosquitto:application/2/node/0000000000000013/rx:state:JSONPATH($.object.adc)]"}
Cool that works!
Now are you sure that this is a temperature?
No temperature is not being sent, But Thank you , couldn’t have done it without your help
