sens text on Adafruit_MQTT.h- is JSOn possible?

[soulid]

Hi there,
I need to send ON and OFF through MQTT to Mosquitto/ Openhab but I am having trouble with it.

I try to send it like that

Code: Select all

  Lichtevent.publish('ON');

In MQTT.FX this is leading to a "20302" only. It would be ideal if this could be send my JSON but the text only would be good as well.

What board and code are you using to send the message?
