Hi.
Yes. You are right.
There was a semicolon missing.

That shouldn’t be there. It’s from other project. It was basically to use icons from fontawesome: fontawesome.com/

Have a question also:
What are the class: “fas fa-thermometer-threequarters” in index.html doing?

The problem was reading the sensors. When I opened the browser and called the sensor reading, the problem happened. Even using the scripts you made available. I changed all the sending logic via WebSocket and managed to make it work. Thank you for your attention.

How are you sending the readings to the web browser?

In the JS console, appears this:

Trying to open a WebSocket connection… script.js:16
Connection opened script.js:25
Failed to load resource: the server responded with
a status of 500 (Internal Server Error) /favicon.png:1
Connection closed script.js:30

Hi.
do you get any errors on the web browser?
Open the Javascript console and check if you get any errors on the browser.
To open the Javascript console:
Windows/Linux: Press Control + Shift + J.
Mac: Press Command + Option + J.

First of all I want to thank you very much for the tutorials that you make available here. Are amazing!! I’m a hobbyist so I have a lot of difficulties, since I don’t know programming in depth. Just a basic.

I’ve been trying to use this tutorial for a personal project but it seems like there’s an error in it.

At first I was only using the WebSocket functions from your tutorial in my sketch and it was giving me a memory allocation error. As my sketch is quite large, I spent several days trying to figure out what the problem was. Today, as I couldn’t find it, I decided to reproduce yours exactly as it is (the only difference is that I use a DS18B20 sensor). And the error also happened, which leads me to believe that there is something wrong with the code you provided.
The following happens:

I compile the sketch in the Arduino IDE and it loads to the ESP without problems. On the monitor, also all right. The SerialsPrints show that everything looks correct. But when I open the browser, almost immediately the problem happens. I’m going to paste here just a piece but it’s quite big. And almost immediately the esp8266 reboots. And again the problem happens. ESP just stops restarting when I close the browser.

The error is this:

Thanks a lot if you can check what might be happening.

Thanks for sharing.
