Blitzwolf/Gosund tasmota plug not communicating over mqtt

Hello Community,
i hope one of you can help me out.
First at all i flashed 5 of my Blitzwolf Sockets and now they are running tasmota 8.
Everything is working as it should be.
I am running openhabian on a raspberrypi 3 over ethernet. Also working good.

Now to my problem, i can’t get the switch turn on/off (or anything else) over openhab. I followed every tutorial i could find for sonoff or gosund/blitzwolf sockets but after 5 days im absolutely clueless…

I’ll post the files i currently use and my settings for openhab and the plug.

At this moment i just try to turn it on and off.

There should be the channels from the mqtt.things, right ?

many thanks in advance.

When you look at the created MQTT thing on PaperUI, what is the channel definition for the channel …powerswitch channel? My guess " :tasmotalicht" is no part of it!

I can’t see any channels in PaperUI… only what you can see in the screenshot.
I tried this

then i got some channels but that also ain’t working.

The screenshot shows the broker thing!
You should have a thing named “bwshp2_1234”.

[Edit]
Looking at your files I would expect the stateTopics to read something like:
stat/tasmotalicht/POWER and the commandTopic: cmd/tasmotalicht/POWER that’s for the first channel, the following change the same way.

My guess for the correct channel setting when linking an item:
mqtt:topic:mosquitto:bwshp2_1234:BW_1234_powerswitch

I tried some old files (had nearly 20) and it finally worked !

with this blitzwolf.items

// Blitzwolf BW-SHP2 #1 (1234)                                                       
Switch BW1_Switch 		  	"Blitzwolf#1: Switch 1" 	     	{ channel="mqtt:topic:mosquitto:tasmotalicht:BW_1234_powerswitch" }

and this mqtt.things

Bridge mqtt:broker:mosquitto "Mosquitto" [ host="localhost", port=1883, secure=false, username="USERNAME", password="PASSWORD", clientID="openHAB2" ]
{
    // Sonoffs
    Thing topic tasmotalicht "Tasmota Smartplug" @ "Some Room" {
    Channels:
        Type string : reachable "Reachable"            [ stateTopic="tele/tasmotalicht/LWT" ]
        Type switch : BW_1234_powerswitch     "Power"                [ stateTopic="stat/tasmotalicht/POWER", commandTopic="cmnd/tasmotalicht/POWER" ]
        Type number : rssi      "WiFi Signal Strength" [ stateTopic="tele/tasmotalicht/STATE", transformationPattern="JSONPATH:$.Wifi.RSSI"]
    }
}

Important:
Working with

[ stateTopic="stat/tasmotalicht/POWER", commandTopic="cmnd/tasmotalicht/POWER" ]

not working with

[ stateTopic="tasmota/tasmotalicht/stat/POWER", commandTopic="tasmota/tasmotalicht/cmnd/POWER", on="ON", off="OFF" ]

@TLDlegal install a mqtt tool to see what is being sent and received. Speaking of mqttfx there are others as well.
