Download the code.

First, you have to install the required libraries. I have shared all the links in the code.

Then enter the API key & WiFi credentials

#define MyApiKey "----------------" #define MySSID "--------"

#define MyWifiPassword "------"

Then enter the device IDs for each device.

String device_ID_1 = "------------------------";String device_ID_2 = "------------------------";

String device_ID_3 = "------------------------";

String device_ID_4 = "------------------------";

String device_ID_5 = "------------------------";

String device_ID_6 = "------------------------";

String device_ID_7 = "------------------------";

String device_ID_8 = "------------------------";

After that select the DOIT ESP32 DEVKIT V1 board and the PORT. Then click on the upload button.

While uploading if you see the "Connecting.....___" text, press the BOOT button of ESP32.
