Great!

Hi Sara:
Please discard my request for help with websocket version of the project. I have managed to convert webserver version to webscoket. Thank you again for your help and support, Regards, Tito

Thanks Sara for your prompt attention to my request.

I am trying to use WebSocket in the project “ESP32/ESP8266 Relay Module Web Server using Arduino IDE (1, 2, 4, 8, 16 Channels)” from https://randomnerdtutorials.com/esp32-esp8266-relay-web-server/ which is WebServer based. When clicking any button in WebSocket version, button is changing in the webpage but noting changing in relays. I think I need to add function in the java script to handle the button change.

Refer to the line in webServer sketch,
buttons+= ”

Relay #” + String(i) + ” – GPIO ” + relayGPIOs[i-1] + ”

“;

But I need to add similar function in Java Script to track onchange of the button and send message through WebSocket.

Can I send you the sketch through email in a zip file?

Thank you again

Hi Sara:
I have been trying to use WebSocket for this multiple relays project without success. I am not very familiar with WebSocket but I think there is issue with event -onchange=\”toggleCheckbox(this). Could you please give me some idea where the function toggleCheckbox is to be in placed? In sketch or in script? Any help will be appreciated. Basically I am struggling with WebServer and WebSocket

Hi.
You need to use the libraries by ESP32Async.
And you need to delete/unninstall different libraries with the same name.

Hello, and thank you for your support of this code. I am getting the same error as Robert Warren, the fix was following the lib links and getting the correct lib’s. the IDE had lib with the same names but didn’t work.

Hi.
Did you install the required libraries? Did you install the correct versions?

Which versions do you have installed?

Sara
