Can anybody help?

Thanks in advance!

  1. You need triple backticks around your code.

  2. How have you got your gauge and superchart configured?

  3. Which value is wrong?

PPM values of measured CO2

As you’ve ignored the information about using triple backticks that was in the information provided when you created the topic, and the reminder from @JustBertC, I’ve removed your unformatted code.

Please edit your original post (using the pencil icon at the bottom of the post) and add-in your code with triple backticks at the beginning and end.
Triple backticks look like this:

Also, if you don’t provide information about the differences between what you see in the serial monitor and what you see in the app, you probably won’t get much assistance with your problem.
