anything interesting in mosquitto.log?
it should have worked by now…
post the contents of /var/lib/openhab2/config/org/openhab/mqtt.config also to check something
post also the output of this linux command (no need to mask IP Addresses of 192.168.x.y kind… they are not routable over the internet).
netstat -atn |grep 1883
make sure that this is not installed:
Yes , MQTT Action is not installed. I double checked it…
/var/lib/openhab2/config/org/openhab/mqtt.config
broker.clientId="openhab254213"
broker.pwd="HomeHub"
broker.url="tcp://127.0.0.1:1883"

ok… try to disable authentication for mqtt to test:
/etc/openhab2/services/mqtt.cfg:

/etc/mosquitto/mosquitto.conf
allow_anonymous true
restart mosquitto and OH2 services
systemctl restart mosquitto
systemctl restart openhab2
monitor both mosquitto.log and openhab.log and post new log info
here are the log file…

so… it works now and your problem is your username/password combo…
I will relook into username/password combo however MQTT bindings is not showing up under configuration -> services.
I followed the below steps in the link correctly but I am not able to move forward in step 3 ( binding settings) . I tried installing /uninstalling ( MQTT Binding (binding-mqtt1) ) multiple times.
( https://community.openhab.org/t/mqtt-binding-v1-11-getting-started-101/33958)
I have created below item file but not able to link it to bindings…
Number:Temperature Temperature "Outside Temperature [%.1f %unit%]" { channel="yahooweather:weather:berlin:temperature" }
Number Humidity "humidity [%.1f]" {mqtt="<[broker:RF24SN/in/2/2:state:default]"}
Switch mySwitch {mqtt=">[broker:RF24SN/out/2/1:command:ON
it will never show
there is nothing that you can configure via PaperUI when it comes to the MQTT Binding v1
full path and filename please for the items file
last line seems to be cut off
check openhab.log for warnings/errors when parsing the items file
Switch mySwitch { mqtt=">[broker:RF24SN/out/2/1:command:*:default" }
Action the switch in your UI, what happens in mqtt.fx?
Full path for item file
/etc/openhab2/items/Myhome.items
Yes, MQTT.fx is communicating using “RF24SN/out/2/1” publish and subscribe… but how Can I bind it to UI…?
READ THE DOCS…
AND WHEN YOU HAVE FININSHED READ THEM AGAIN!!!
@rajeev2301
By the way, a little thank you for getting your stuff working would have been nice, after all 2 of us two 2 days to get through to you.
Some of the rest now you will have to figure out by yourself. The are the docs, the forum.
Search the forum before asking trivial questions. Chances are, someone asked the question before.
But ALL you need is in the docs. Read them, again and again.
Follow the docs, step by step. Don’t skip any
Check for typos
Don’t try to improvise. You do NOT know better.
openHAB is hard. At the beginning you WILL struggle. But that struggle will make you learn. If we tell you everything then you won’t learn and to be honest we have better things to do than telling you stuff that’s in the docs, that you should have been reading in the first place.
Good luck
Hi
I am back after two days on road. THANKS to both of you for extending your support. I will go though the ref doc and try to build the remaining configuration. Still need to figure out the issues on MQTT username/password combo.
You guys are great and contributing a lot to this community. I hope one day I will able to do same as well.
Tomorrow I will be back in my home lab to complete the ramaining work. Will keep you guys posted.
THANKS!

After reading the documentation over and over I must admit that I need help.
I had setup my ubuntu virtual server with openhabian and just before I got to the point to consider my installation stable enough that backup is the next step, my mqtt binding stops to work.
mosquitto is up and running and I can switch ON and OFF my tasmota powered sonoffs.

Is the MQTT action installed?
Yes, MQTT action is also installed.
edit: I was wondering what your question is about and uninstalled the MQTT action. Suddenly the MQTT binding started to work again.
unfortunately, there is still an open issue on this: [MQTT with MQTT Action] MQTT Binding will not connect with action installed · Issue #5038 · openhab/openhab1-addons · GitHub
With MQTTv2 we won’t have this problem anymore 
Yes!! That’s what the question was about. If you uninstall the action, restart openHAB and re-install the action it should be ok again.
Please mark the thread as solved
Thanks
i’ve made a video tutorial how to install and setup new OpenHAB MQTT binding, maybe it’ll help someone. (russian language video)
Я сделал видеоурок о том, как установить и настроить новый OpenHAB MQTT биндинг, возможно, это кому-нибудь поможет быстрее разобраться в этом вопросе (видео на русском языке)
Thanks!
