I try to visualize the blue part on the Node-RED dashboard.
Somebody can help me?

Welcome to the forum @WillemEco. The first thing to do is to have a good read of the node red guide on Working with Messages which will show you how to access a particular item from the message. Most of the dashboard nodes allow you to specify which value in an object to display so you should not need to extract it first.

If you configure the MQTT node to output Parse JSON it will automatically parse the JSON string and pass on the javascript object so you can then remove the JSON node.
