Lots of RFID tag thru mqtt as trigger

Hey there!

Long story short… I want to trigger one automation with 50 different RFID tag. HASS receives the tags as mqtt string from an esp8266 chip.

The mqtt message AKA states.sensor.rfid.state looks like this: 53ded3f0

Templates i guess?
Maybe a txt file with all the scanned (mqtt) strings?

how you do this?
