[SOLVED] MQTT not sending command in OH2?

Hi there,

I’ve managed to get mqtt up and running again after migrating from 1.8. Problem is that the message doesn’t seem to be sending when I flick a Switch from ON/OFF and vice versa.

If I use mosquitto_pub manually with the following it works!
mosquitto_pub -t ‘ninjaCape/output/11’ -m ‘101001100011100100000010’

but the following item doesn’t seem to work?

Switch K_Light “Kitchen Lights”

Please check what is in the log and make sure that “mosquitto” is properly defined in mqtt.cfg
And please fix formatting error in your post - note > symbol in the binding configuration.

Thanks. Fixed the format. Mqtt.cfg has mosquitto.url=tcp://localhost:1883

I assume that’s correct?

That’s correct and the rest looks good for me. I’m wandering what is in the log.

Thanks for checking. Which log would that be? openhab.log has no errors relating to this. What I did notice is that my when I boot openhab, the original client name “oh2” still appears before mosquitto which is what I changed it to… Could this be a problem?

The null issue is just a mapping error…

You seems to have 2 connections defined. I suggest to remove 1 to avoid confusion. Then you could probably enable debug for mqtt and check what’s going on there when you sliding the switch.

Look in userdata/config/org/openhab/mqtt.config. There is a bug where removing fields from a cfg file so not get removed from that file which can cause problems.

For apt-get userdata is in /var/lib/openhab2

Thanks - that worked to remove the unused oh2 mqtt, unfortunately doesn’t resolve my problem.

How do I enable / check mqtt logs? Do I need to do it through karaf?

From what I read, I need to enable more detailed logging for the mqtt binding. I’m getting this though - seems I can’t login to the karaf console?

[10:18:09] pi@openHABianPi:~$ ssh openhab@localhost -p 8101
Received disconnect from 2: Session has timed out waiting for authentication after 120000 ms.

Edit: Nevermind - just made it in - had some time…

Sorry, bear with me:
I put this in:

log:set DEBUG org.openhab.binding.mqtt

but the logs show nothing when i flick the switch in my browser in either log:tail or openhab.log. I know there’s something going on in mqtt because I have two of my doors sending messages through an ESP8266 via MQTT and it’s registering the correct switches

That is what it looked like when I had the problem with the MQTT action preventing my MQTT binding from working.

Anyone got any ideas? Or how I go about debugging this? I’m out of ideas here… Thinking of using exec binding to run the mosquitto_pub command

update for everyone.

Here’s where I went wrong. I was using HABMIN UI to control my switches which actually wasn’t doing anything at all!

Not sure what’s going on with that. I changed ClassicUI to my sitemap and used that instead and everything’s working now.

Resolved. Thanks all.

Hi there!

I know that it is an old post but it may be related to my issue that I can’t get rid from error messages caused by old, unused broker like mqtt1, mqtt_test etc…

I cleaned my mqtt.conf file but errors are still there.

My config file:

07:18:12.383 [ERROR] [t.mqtt.internal.MqttBrokerConnection] - MQTT connection to broker was lost

I know from your post that it is a bug but is there any solution to remove the unused brokers?


Thanks, this solved all the problems!
