MQTT Connection issues

[TobiTechnik]

Hey there,

i got a projekt, for that i bought the KinCony KC868-A16 and an RaspberryPi4.
Currently I´m trying to connect the Kincony board and Raspberry with Mosquitto to Node Red.
Mosquitto is running and I´m able to send and recive messages when i try it from my Pi to recive a message on nodered.
I´m able to ping the KinCony Board and connect with it with WLan to change the settings on the Board.



What am I missing that I don´t get the connection via MQTT and NodeRed?
When it would work, how does the topic for the MQTT message have to look like?

Thanks in advance for the help.

here is mqtt protocol document: https://www.kincony.com/forum/showthread.php?tid=3105
i think you can't use mqtt://127.0.0.1 you should use a pc actual ip address.
