Hi everyone,
I am running openHAB of a Raspberry Pi3 and am just now starting to get it all setup. My very first task to try and get some sonoff basics working via Tasmota and MQTT. They have all been flashed and are working.
The following was all done via the PaperUI.
I added the MQTT Binding and the MQTT Embedded broker to the system. Went through and set them up and tested them with MQTTfx. Everything works just fine (I was able to connect to the MQTT server and send/receive topics). So I configured my Sonoff for the MQTT server, and I then subscribed to the command and state topics on MQTTFX and when I press the button on the sonoff I can see the topic being sent in MQTTfx and I can also publish a topic from MQTTfx and see the sonoff change states.
Everything seems to be working as expected.
Next step was to add the sonoff as a generic MQTT thing with the embedded MQTT Broker as it’s bridge and this went fine, and the thing showed up as online and happy. Next was to add the channel to the it, which I did, giving it the state and command topics that I verified as working in MQTTfx. As soon as I did this the thing went from online to:
OFFLINE - COMMUNICATION_ERROR java.lang.Exception: No MQTT client
I plowed on and linked a new switch item to it, which shows up in the control section, toggling that does nothing. I have even gone so far as to delete everything and start all over about 2 or 3 times, with no luck.
Spending an hour trying to google this issue did not really yield much of anything, and I have no idea what is going on here. I am running version 2.5 of openHAB which apparently fixed a bug that could cause this, so that’s not it. There were some mentioned of editing a MQTT.cfg file, but that file is missing on my install. Lots of mentions to editing config files manually, but no mention of where these files as (and my /etc/openhab2/things folder is empty).
So what I am doing wrong here? How do I get this working?
