Add variable in html ESP32

Fast question: how do I get a variable into a HTML file in Flowcode?

I did that ones in FC, in a wired module but can't find the file anymore.
Any directions to an example?

I want to add a temperature into a HTML-file..

Thanks.

Hi MJU20

You can use the %1.....%10 to set in the HTML Code

Maybe this two sample help

YES!! That was what I was looking for!
Thank you stefan.erni.

Too bad I can't read the example files.
I don't have the app develop tools..

Do I need to name the variable in FC %0?

Attached is one of those projects saved as a .fcfx file. It might not work in this form, but at least you should be able to load it and see what is happening.

The WebServer component allows you to change the values of the %1 (etc) substitution variables using the macro "SetOutValue".

Thank you Steve,

I will examine it.
The "Indicator" can be replaced by a common LED I guess.
