RFID with MQTT

[Rupert van Swol]

Dear Forum,
I'm messing around a bit with an RFID reader.
It would be nice if an RFID system could be used in Windigipet2025  as a shunting tool for the wagons.

I have managed to get MQTT Explorer to show the Tag information of a wagon with Tag 1788.

WDP2025demo has contact with MQTT broker there the connect button is on green  , but I don't see it appearing as a device.
 
What have I overlooked.
 
And second  how do I get the Text ' 1788' in from Vport 19 and 11.

Am very curious to see how this development continues. 

The set comes from the UK
The system consists of a reader and a display unit .
