is anything useful in the logs?
read again the examples that Thom posted, You will get it working 
(it seems that your broker connection is fine)
[19:34:12] openhabian@openHABianPi:~$ lsof -i :1883
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
mosquitto 7105 openhabian 5u IPv4 21570 0t0 TCP localhost:40962->localhost:1883 (ESTABLISHED)
ANYWAY… these are my settings now:
sonoff device TH16:
Client Id = OH2MQTT
Topic = sonoff1
Full Topic = tasmota/%topic%/%prefix%/
items (according to @ThomDietrich) :
Switch Sonoff_TH16A "Balkonmagic" <stars> {mqtt=">[broker:tasmota/sonoff1/cmnd/POWER:command:*:default], <[broker:tasmota/sonoff1/stat/POWER:state:default]"}
Number Sonoff_TH16A_RSSI "Balkonmagic RSSI [%d %%]" {mqtt="<[broker:tasmota/sonoff1/tele/STATE:state:JSONPATH($.Wifi.RSSI)]"}
Switch Sonoff_TH16A_Unreach "Balkonmagic unreachable" <siren> {mqtt="<[broker:tasmota/sonoff1/tele/LWT:state:MAP(unreach.map)]"}
mqtt.cfg:
[19:59:02] openhabian@openHABianPi:~$ cat /var/lib/openhab2/config/org/openhab/mqtt.config
mqttson.clientId="openHAB2"
mqttson.url="tcp://127.0.0.1:1883"
service.pid="org.openhab.mqtt"
So.. does it work?
I feel like both of you should take a step back. For example in your posting the Client Id = OH2MQTT - Do you know what this means? Your setting doesn’t make much sense, you should just leave it with the default setting. Next your Topic setting. Why sonoff1? Give it a meaningful name, something you can work with (e.g. “sonoff-coridorlight”, not too long, no underscore).
Your config looks okay. You can again leave the client Id setting commented to have a random one generated. I take it your broker doesn’t provide authentication? If you’ve installed via openHABian setting up a password was offered.
After you’ve set up everything do a test. You could for example restart openHAB, then wait a few minutes and check the log for mqtt related messages. It should look similar to this one:
[21:22:34] openhabian@openHABianPiW66a:~$ grep "mqtt" /var/log/openhab2/*

sadly it doesn’t
Client id - it’s the id i’m connecting to the broker?
which part of the (mqtt.cfg?) setting doesn’t make sense?
why sonoff1? because for now i have two sonoff devices and this is the one i’m testing with (i’m not sure where the device will be installed later, so a meaningful name would be hard to find)

2 mqtt broker configs… did you clear /var/lib/openhab2/config/org/openhab/mqtt.config ?
Since when is this really needed? I personally never had to mess around in these files…
followed these steps (again), same result:

I have never seen this before…
question: do you have the MQTT Action addon installed?
check something please within the openHAB console (post the output):
config:list "(service.pid=org.openhab.mqtt)"
config:list |grep -i broker
You can also increase the log levels to see if something more interesting comes up:
log:set TRACE org.openhab.binding.mqtt
log:set TRACE org.openhab.io.transport.mqtt
yes. just uninstalled it, but log doesn’t change.
[quote]check something please within the openHAB console (post the output):
config:list "(service.pid=org.openhab.mqtt)"
config:list |grep -i broker
```[/quote]
```php
openhab> config:list "(service.pid=org.openhab.mqtt)"

done
restart OH2 after uninstalling the action addon.
There is a logged bug about this (the action addon does not allow the mqtt binding to connect)
this doesn’t explain the 2nd connection… and I don’t see anything wrong in your console output… still a mystery where this 2nd connection is coming from…
by the way: you can always try the… nuclear option… 
backup configs, purge (press the red button), re-install, restore configs
log was the same after reboot.
now reboot with TRACE log:

nuking is not an option. cost me a day last time to get it working again 
so… no messages regarding Starting MQTT broker connection for the 2nd ‘broker’ config in the log? (only for the correct ‘mqttson’)?
..but… logged messages about Stopping broker connection for the 2nd ‘broker’ config…
while nothing shows up as trying to start a 2nd connection (and no configs can be found)… this 2nd connection is actually initiated from openHAB towards the broker that conflicts with the correct 1st one, not allowing the binding to establish a correct link… so nothing MQTT related works…
I am about to give up
Last try:
stop OH2
clear the contents of your /var/lib/openhab2/tmp/ & /var/lib/openhab2/cache/ dirs
start OH2
rm -ir /var/lib/openhab2/tmp/*
rm -ir /var/lib/openhab2/cache/*
Ps: Is there a /var/lib/openhab2/tmp/broker dir in there?
except this one:

omg - how many times do i have to confirm the remove command???
I gave you the safe option…
there is always the dangerous option (not interactive… but force remove)
rm -rf /var/lib/openhab2/tmp/*
rm -rf /var/lib/openhab2/cache/*
where in HELL is this config stored??? I can’t understand where this is coming from…
Is there any other kind of config file that holds such info (about a broker) in your /etc/openhab2/ subfolders?
cd /etc/openhab2/services/
grep broker *
check also the other subfolders
another trick would be to set the url configuration property manually for this broker guy:
config:property-set -p org.openhab.mqtt broker.url tcp://192.168.0.1:1883
or try
config:property-delete -p org.openhab.mqtt broker.url
(basically, set a fake url for this guy so he doesn’t cause errors)
but this doesn’t make sense since this config property didn’t show up when you did config:list
alright, removed everything in those to folders and rebooted:
