Can't get mqtt to start in OH 2.1

Add-ons Bindings
1

I have been running my OH connected to a RabbitMQ for a very long time. However, for a while now I can’t get OH2 to start/connect to the mqtt-bus.

If I separate log files for mqtt, and set TRACE level of logs, this is what shows up in my mqtt.log:

2017-10-31 22:05:13.536 [DEBUG] [org.openhab.binding.mqtt            ] - BundleEvent STARTED - org.openhab.binding.mqtt

However, I can’t see that it actually starts the eventbus and from what I see in RabbitMQ, there is no connection to the bus from OH2.

My mqtt.conf:

wimnellnet.url=tcp://192.168.0.21:1883
wimnellnet.clientId=openhabclient
wimnellnet.user=user
wimnellnet.pwd=password

My mqtt-eventbus.conf:

broker=wimnellnet
statePublishTopic=openhab2/out/${item}/state
commandPublishTopic=openhab2/out/${item}/command

I’ve tried to delete the config files using config:delete command in Karaf and then restart, but same problem. I realize that I’m doing something wrong here (or have some miss-configuration) but I can’t find the obvious. Anyone see the reason?

Best regards,

Have you verified the MQTT I/O transport is running?

3

Yes,

Feauteure:list | grep mq

Shows transport as ”started”.

I’ve also tried to install and uninstall mqtt-action - without any luck.

I think probably one of those mqtt transports should go away. (esh-io-transport-mqtt or openhab-transport-mqtt)
Probably the openhab-transport, if you’re using OH2.

Ok,

Well - Now I’ve tested with openhab-binding-mqtt1 and esh-io-transport-mqtt. Did not work, so I changed to openhab-transport-mqtt instead Didn’t work either :frowning: Back to square 0.
