Okay lets start.  
We need input.

Give us your /etc/openhab2/services/mqtt.cfg  
Give us your /etc/openhab2/items/mqtt.items  
Give us a Screenshot of your Sonoff Device\>Configuration\>MQTT  
Do you use openHABian?  
openHAB 2.X ? Which one?  
Did you read the [MQTT Docs ?](http://docs.openhab.org/addons/bindings/mqtt1/readme.html)  
Did you read this Topic ? [ITEAD Sonoff switches and sockets - cheap ESP8266 Wifi+MQTT hardware](https://community.openhab.org/t/itead-sonoff-switches-and-sockets-cheap-esp8266-wifi-mqtt-hardware/15024)  
Did you check out the [Tasmota Wiki?](https://github.com/arendst/Sonoff-Tasmota/wiki)

mqtt.items example

```csv
Switch a_Licht_Outdoor_Sonoff4Channel_2_Biertisch "Lichterketten Biertisch" (g_Outdoor, g_MYSQL) { mqtt=">[mosquitto:cmnd/sonoff-80786B/POW
ER2:command:*:default], <[mosquitto:stat/sonoff-80786B/POWER2:state:default]" }

```

mqtt.cfg example

```csv

I could bet your broker is not named broker, for me I named it mosquitto. Followed the wiki.
