How to update page manually

[ghost]

Hi,

sadly I am not experienced with HTML. Managed it to build a page that works using this library (thanks for that :) ). But I have the problem that values on my ESP do change and I would like to update them on the page accordingly.
I have tried with
mServer.send(200, "text/plain", _PAGE_LLAMP);
but with no success.

I can post my classes here if it is helpful. But there must be a simple way to just update the page or trigger the page to update by itself, maybe by allinging the call above or something?
