Variables with JSON configuration

[2veinte]

Hi, I am integrating a fingerprint sensor using ChirpStack and MQTT to FUXA. The message correctly arrives at the broker with the following structure:
{"object": {"userID": 1, "username": "Engineer"}}

In FUXA, when binding a Tag to the MQTT topic, the visual shows me the entire JSON string instead of filtering just the value. I've tried setting the Attribute field (JSON Path) to object.username, but it doesn't seem to be "trimming" the data.

My configuration:

Connection: MQTT Broker (Mosquitto on localhost)

Address: application/1/device/+/event/up

Tag Type: String

Is there any additional configuration in the Parser or Tag definition so that FUXA processes the JSON correctly and does not display it as plain text? Thank you!

Hi @2veinte I suggest you take it as a string and process it in a script; you can already do this at the tag options
