(SOLVED)MQTT OH2 Problems with the 1.9 binding

Add-ons Bindings
3

Have i miss something guys??

I install MQTT binding starting from PAPER UI and edited the related .cfg file

I have to do something else?

I find out these post but i don’t know if I have to follow it, because I dont want to use OH 1.X binding legacy, I will create a new stable based only on OH2 after the official stable release.

MQTT and OH2 - not working

Please let me know,
Thanks
