So, I’ve been working a bit more with this and I found the homie validator here: The Homie convention
That helped me quite a lot. My device now looks like below paste. Now I can dim the device (only with manual input of numbers though - but it works), and I can see the watt usage. But I can not use the switch. In OpenHAB it doesnt even read the name, so I believe there is an error in one of the inputs. Not sure which one yet.
Does anyone have a link to documentation for MQTT Homie for OpenHAB? Specifically which types are available and examples of data?
