Could you make a short video of your Node-Red Dashboard coding and change the humidity to be recorded on the chart along with the temperature.

You have been using Node-Red Dashboards a lot in Arduino IDE and Python IDE’s but never explaining how you get the Node-Red coding. This is such a great concept that I think we would like to know more. And you do such a great job in explaining each step that I believe a short video would clear up a lot of questions on using MQTT and Node-Red.

Thank you again for such great projects with great explanations.

Hello, right now I can’t do that exact project, because I’m already working on too many projects at the moment, but thank you for the suggestion!

Basically, you need to connect the 2 MQTT IN nodes with the MQTT temperature and MQTT humidity topics to the same Chart node.

Then, they should display the two values in the same chart.
