How to connect to two different Things (Devices) on Arduino IoT Cloud using one ESP8266 module

Software IoT Cloud
1

Hello,

I'm able to connect my ESP8266 module with Arduino IoT Cloud.
And it is working fine.

Here is my code...

#include <ArduinoIoTCloud.h>
#include <Arduino_ConnectionHandler.h>

CloudLight my_LED;

const char DEVICE_LOGIN_NAME[]    = "0f16dd88-377c-4e48-855a-e4836eaa2137";
const char DEVICE_KEY[]           = "DV#3bHvImGaiGZ?goOTcFNhi!";
const char SSID[]                 = "My_WiFi";
const char PASS[]                 = "12345678";

WiFiConnectionHandler ArduinoIoTPreferredConnection(SSID, PASS);

void setup() {
  pinMode(1, OUTPUT);
  ArduinoCloud.setBoardId(DEVICE_LOGIN_NAME);
  ArduinoCloud.setSecretDeviceKey(DEVICE_KEY);
  ArduinoCloud.addProperty(my_LED, READWRITE, ON_CHANGE, onMyLEDChange);
  ArduinoCloud.begin(ArduinoIoTPreferredConnection);
}

void loop() {
  ArduinoCloud.update();
}

void onMyLEDChange()  {
  digitalWrite(1,my_LED);
}

Now, I want to connect to two different Things (Devices) of Arduino IoT Cloud with my ESP8266 module.

Is it possible to do this?

If yes, please share the example code.

Hi @brijesh_investing. You should only use an Arduino Cloud IoT Device in a single Thing at a time.

If you no longer need to use the Device in a given Thing, you are welcome to attach it to a different Thing, but it should only be one thing at a time.

If you need multiple Things at once, then you should get an additional board and create a new Thing for that new board.

You can use the Variables from multiple Things in the a single Arduino Cloud IoT dashboard if you want to use a single interface to interact with several Things.

Thanks @ptillisch for the quick reply.
My doubt is now clear.

You are welcome. I'm glad if I was able to be of assistance.
