I have openHAB 3.1.0 installed (upgraded from 2.x → 3.0 → 3.1).
I just started to look into the MQTT-binding.
The communication between the IoT-device and the MQTT-broker (installed on the same raspberry pi 4 as openHAB) works find as I can see the published data.
The problem is I can not subscribe to the topic.
I have been following this guide: Add Things - Advanced
Up until the step where I have to “Add Channel”. The “window” in the guide does not look the same as mine. Mine looks like this (after I have clicked on “Publish Trigger”):
Any suggestion on how to proceed?
