- Issue of the topic: Using Generic MQTT Binding, transformations of the VALUE received from MQTT does not seem to have effect
No matter what transformation I would add ITEMs value is NULL (exept if there is no transformation, then whole JSON is output as a string)
Tried with items of NUMBER and STRING just to test. Cant get any of them to get transformed value. Example (like in screenshot):
JSONPATH:$.rssi
always outputs NULL on NUMBER items
always outputs FULL JSON on STRING items
