RFID Tag reader

[lumjajo]

Hi,
I have a RFID Reader for my garage door. The reader gives the TAG ID into a ESP8266 with ESP Easy. with the rules there I can open the door.
However, I can also give the ID to Domoticz via the idx. The only problem is, that I do not know which virtual device i should set up to fetch the ID as a pure number.
I want to use this number then in a script and count the entrance etc.
Any idea which virtual device I should set up to get it work?
Thanks
Joachim

You must use a virtual text sensor.
