I would like to build a simple IoT dashboard with custom hardware. My low-level goal is to display values with text or meters. My high-level goal is to plot data vs. time. What are the appropriate tutorials to follow to accomplish these goals? At present I have MQTT sending JSON and the text tile can display the entire message. It is not clear how to parse out the appropriate fields. The tutorials that I have found must be out-of-date because they do not match the current GUI.
Thank you,
Mark
