Yes. I have uninstall the UMH-Stack and setup a Mosquitto MQTT-Broker in a Docker-Container with the same Port on the same Host. I enabled the anonymous login, and the Thermometer did connect and sends data. Only to the UMH-Broker i can't be connected. With netstat -tunlp i didn't see a open Port 1883. But i see the Pod with the Port, if a clicked through the pods over the UMH-Management App.
