Generic MQTT Binding Transformations dont work

  • 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):
always outputs NULL on NUMBER items
always outputs FULL JSON on STRING items

Have you installed any of the optional transformation service add-ons?


OMG… Delete this post… :man_facepalming: Spent like 3h reading and no where noticed that JSON transformation is service add-on…
