I was defining a MQTT Broker and MQTT generic thing which is working well. I just want to transform a string incoming through MQTT message into a temperature by using ONLY Paper UI. Is that possible?
With a String as an Item that is working (see screenshot) - but for a number (temperature) I was just giving up after 5 hours of trying. As I said the message and update of item as a string is working - as a number not. There is no information in the log.
What can I do to define that MQTT Thing link/transform in the Paper UI if possible?
Any hint appreciated!
Transformation for the “incoming value transformation” for string is: JSONPATH:$.temperature
