MQTT binding, broker configured but not used

[BryanLee (Bryan Lee Ragon)]

Openhabian installation. Trying to get OpenHab 2.4 working with mosquitto and some Tasmota Sonoff devices.

Mosquitto and the Sonoffs are working just fine. I can subscribe to their topics, see state changes and publish topics that switch the lights.

I have installed the MQTT binding through Paper UI.

I have edited my mqtt.cfg file:

    pid:org.openhab.mqtt
    mqtt.qos=1
    mqtt.retain=true
    mqtt.async=false
    mqtt.url=tcp://127.0.0.1:1883
    mqtt.clientId=oh2
    mqtt.user=openhabian
    mqtt.pwd=ObligatoryPwd

And my mqtt.cfg items file:

Switch sonoff_attic_light "Attic  Lights" { mqtt="<[mqtt:stat/sonoff-light-attic/POWER:state:default], >[mqtt:cmnd/sonoff-light-attic/POWER:command:ON:on], >[mqtt:cmnd/sonoff-light-attic/POWER:command:OFF:off]" }

In the console:

>config:edit org.openhab.mqtt
>config:property-list
   mqtt.async = false
   mqtt.clientId = oh2
   mqtt.pwd = ObligatoryPwd
   mqtt.qos = 1
   mqtt.retain = true
   mqtt.url = tcp://127.0.0.1:1883
   mqtt.user = openhabian

Log:

2018-12-27 07:52:45.570 [WARN ] [g.dispatch.internal.ConfigDispatcher] - The file /etc/openhab2/services/mqtt.cfg subsequently defines the exclusive PID 'org.openhab.mqtt'. Overriding existing configuration now.

2018-12-27 07:53:08.858 [INFO ] [el.core.internal.ModelRepositoryImpl] - Refreshing model 'mqtt.items'
2018-12-27 07:53:08.887 [ome.event.ItemUpdatedEvent] - Item 'sonoff_attic_light' has been updated.

So it appears that it is not even trying to connect to the broker. Any ideas?

I have installed the MQTT binding through Paper UI.

Which MQTT binding did you install? v1 or v2?

[vzorglub (Vincent Regaud)]

If you are using v2, see:

Using Sonoff Power Switches with Tasmota firmware and openHAB2 MQTT2 binding

Hi guys, after hours of working on my openHAB2 configuration for my Sonoff Smart Switches, using the Tasmota firmware, I got that running, using the new MQTT2 binding. As for now I have 7 Sonoff Power Switches and didn’t want to configure them through PaperUI. After a hint from @Dim I got my configuration completely in files, providing me with the ability to do some slight changes on all channels at the same time. This is just meant as an example and I would be more than happy, get more hints …

If you are using v1 see:

ITEAD Sonoff switches and sockets - cheap ESP8266 Wifi+MQTT hardware

ITEAD Smart Home Products [image][image][image] These very cheap modules come with their special smartphone app but are all actually based on the famous ESP8266. It didn’t take long till the tinkerer community got a hold of that and started hacking. After opening up the cases, all you need to do is solder a few header pins and connect your FTDI breakout programmer. Alternative firmwares are ready to provide nice MQTT based Wifi SmartHome endpoints without the need to either pay a lot of mone…

@vzorglub

Paper UI → Add Ons → Bindings → MQTT (binding-mqtt - 2.4.0)

I will double check the MQTT2 binding Tutorial you listed, thank you!

[BryanLee (Bryan Lee Ragon)]

Yeah, I was definitely confused. Still doing my initial setup and didn’t realize the MQTT binding underwent a major upgrade during that time. Still fighting to get it working, but I’ll leave this thread as is and start a new one if I need to.
