Hello Have you pass the trigger id in HEX format? writing in a Nextion Event the command: printh 23 02 54 XX , where XX the id for the triggerXX() in HEX For trigger10() printh 23 02 54 0A

Thanks for your quick response, Yes, changing the digits to hex fixed the problem. Further thanks for your excellent abstraction and simplification for the Nextion interface.
