Hi @vivekgs27,

Cayenne is cloud based, so yes for right now in order to use the powerful features of Cayenne you’ll need to connect your Arduino to internet. Have a local server version of Cayenne is on the roadmap, but still will not be for some time.

Welcome to the Cayenne community!

You can however connect your Arduino to Cayenne via the Serial USB Connection option if you don’t have an Ethernet/WiFi shield. You should see it on the list of sketch options when you’re adding the Arduino via Add New > Device/Widget > Microcontroller

Bumping this old thread to share that we’ve just provided support in our MQTT Arduino library for using ESP8266 as a shield We’ve done basic testing and works well. Give it a try for your project and let us know how it works out for you !

Here is the updated library on our github:

and the code can be found here:

github.com

myDevicesIoT/Cayenne-MQTT-Arduino/blob/master/examples/Connections/ESP8266Shield/ESP8266Shield.ino

/*
This sketch connects to the Cayenne server using an ESP8266 WiFi module as a shield connected via a hardware serial to an Arduino.

The CayenneMQTT Library is required to run this sketch. If you have not already done so you can install it from the Arduino IDE Library Manager.

Steps:
1. Install the ESP8266SerialLibrary.zip library via the Arduino IDE (Sketch->Include Library->Add .ZIP Library) from the Cayenne extras/libraries
   folder (e.g. My Documents\Arduino\libraries\CayenneMQTT\extras\libraries) to compile this example.
2. Connect the ESP8266 as a shield to your Arduino. This example uses the Serial1 hardware serial pins available on the Mega. You can also try 
   using a software serial, though it may be less stable.
3. Set the Cayenne authentication info to match the authentication info from the Dashboard.
4. Set the network name and password.
5. Compile and upload the sketch.
6. A temporary widget will be automatically generated in the Cayenne Dashboard. To make the widget permanent click the plus sign on the widget.

NOTE: This code requires ESP8266 firmware version 1.0.0 (AT v0.22) or later.
