Hi,
I am a beginner and I have some sensors grovepi sensors reading data and sending to mqtt. The data is sent as Json (if I am understanding this right)
Then I am trying to get for example the brightness data to be displayed in the ui as gauge but I dont know how to do it, my first attempt was to grab a mqtt input node and connect to the gauge
Obviously I am doing something wrong there and this noob here needs some guidance please.
