MQTT Binding with multiple things

Hi,

I am working with the new MQTT 2.4 plugin. I am still trying to get the configuration for it running. I just don’t know what I might be doing wrong.
This is my current configuration:

Bridge mqtt:broker:brokerhome [ host="10.0.2.41", secure=false ]{
    Thing topic MQTT_Lupi_Weather {
        Channels:
        Type number : lupi_temperature "Temperatur" [ stateTopic="lupi-weather/sensor/temperature" ]
        Type number : lupi_pressure "Luftdruck" [ stateTopic="lupi-weather/sensor/pressure" ]
        Type number : lupi_brightness "Helligkeit" [ stateTopic="lupi-weather/sensor/brightness" ]
        // lupi-weather/sensor/pressure lupi-weather/sensor/brightness
        //Type switch : fernbedienung_Schlafzimmer_Power "Fernseher Schlafzimmer" [ stateTopic="Haus/Fernseher/state", commandTopic="Haus/Fernseher", on="power", off="power" ]
        //Type number : feuchtigkeit_node "Feuchtigkeit Node[%.1f %%]" [stateTopic="Haus/Sensor/Feuchtigkeit"]
    }
    Thing topic MQTT_WDE1 {
        Channels:
        Type number : temperature "Temperatur" [ stateTopic="openhab/garten/temperature" ]
        Type number : humidity "Luftfeuchtigkeit" [ stateTopic="openhab/garten/humidity" ]

        //openhab/garten/temperature; openhab/garten/humidity
    }

    Thing topic MQTT_TVLED {
        Channels:
        Type colorHSB : TVLED_Color "Farbe TV LED" [ commandTopic="cmnd/tvled/HSBColor"]
        Type number: TVLED_Dimmer "Helligkeit TV LED" [ stateTopic = "tele/tvled/STATE", commandTopic="cmnd/tvled/Dimmer", transformationPattern="JSONPATH:$.Dimmer"]
    }
    Thing topic MQTT_NixiePower {
        Channels:
        Type switch : Power "Funksteckdose" [ stateTopic = "tele/NixieSteckdose/STATE", commandTopic="cmnd/NixieSteckdose/POWER", transformationPattern="JSONPATH:$.POWER"]
    
    }
    Thing topic MQTT_Temp1 {
        Channels:
        Type number : temperature "Temperatur" [ stateTopic ="tele/tempsensor1/SENSOR" , transformationPattern="JSONPATH:$.AM2301.Temperature" ]
        Type number : humidity "Luftfeuchtigkeit" [ stateTopic ="tele/tempsensor1/SENSOR", transformationPattern="JSONPATH:$.AM2301.Humidity"]
        // {"Time":"2019-01-07T21:14:06","AM2301":{"Temperature":24.8,"Humidity":44.9},"TempUnit":"C"}
    }
    Thing topic MQTT_PIR1 {
        Channels:
        Type switch : motion "Bewegung" [ stateTopic ="stat/pir1/POWER" ]
        //{"Time":"2019-01-07T21:32:04","Switch1":"OFF"}
    }
}

None of the channels seems to receive its updates. The MQTT server IP and the messages are double-checked.
An example Item would be:

Switch DG_BR_PIR1 "Bewegungsmelder unter dem Bett" <motion> (DG_BedRoom) { channel="mqtt:topic:brokerhome:MQTT_PIR1:motion"}

Is it allowed to have multiple things on one broker?
Any hints?

Yes of course
