Hi i have installed the latest openhabian image on a Raspberry 3B+ and installed additionally mosquitto as mqtt broker with mqtt binding from AddOns.
I did the mqtt coniguration and mosquitto starts und works.

2018-09-03 19:50:08.560 [ome.event.ItemCommandEvent] - Item 'RingoDemo' received command ON
2018-09-03 19:50:08.599 [vent.ItemStateChangedEvent] - RingoDemo changed from NULL to ON
my item looks like many examples i see for sonoff
Switch RingoDemo "RingoDemo" {mqtt=">[broker:cmnd/sonoff-touch1/POWER:command:*:default],<[broker:stat/sonoff-touch1/POWER:state:default]"}
The mqtt setting on the sonoff switch are working and connecting to mosquitto

I can trigger my switch with mqtt.fx windows client but openhab did not send or receive any mqtt messages.
mqtt.cfg
<broker>.url=tcp://localhost:1883
<broker>.allowLongerClientIds=false
<broker>.user=myuser
<broker>.pwd=mypass
<broker>.qos=0
<broker>.retain=false
<broker>.async=true
Any Ideas whats wrong with my mqtt configuration ?
