How can I set node-red to use the value of "power" in a gauge?
I've tried with using "http-response", "function" and "gauge", but I'm not sure how to program it. I guess its a simple thing for those who am more experienced than me.
I created a http request with GET and the weblink I had. Then json with msg.payload, and then for a test I used a text function with the value {{msg.payload.power}}. It worked.
