Build Status

What is OpenDevice?

OpenDevice is a set of tools and APIs to build solutions for the "Internet of Things" like home automations systems, robotics, smart city, energy monitoring, security, sensor monitoring.
Provide an open and unified framework to interconnect IoT devices, data, and applications over the Web, if you need communication between software and hardware, probably your place is here.

The main objective is monitor and control inexpensive hardwares like Arduino, ESP8266, RaspberryPI and similar platforms, local(offline) or over the cloud using high-level programing languages and with abstraction of protocols and low-level details.

This allows you to focus on your project and innovation, leave obscure details of communication protocols and specifications with OpenDevice, you will make a major step towards the success of your project.

Plug your device (Arduino/Raspberypi/Other) to the Cloud and sync in real-time

Code Sample

Simple like this (Java/Android):
    public class BlinkDeviceDemo extends LocalDeviceManager {

        public static void main(String[] args) { launch(args); }

        public void start() throws IOException {

            Device led = new Device(1, Device.DIGITAL);

            connect(out.usb()); // Connect to first USB port available


But not only that…​ (You can also do in javascript and other languages.)

Arduino Side:
#include <OpenDevice.h>

void setup(){"ODevSerial");
    ODev.addDevice("LED1", 13, Device::DIGITAL);
    ODev.begin(); // by default call Serial.begin() and while(!Serial) on Leonardo

void loop(){
ESP8266 connected to OpenDevice MQTT Server:
#include <ESP8266WiFi.h>  // Enable ESP8266 Wifi
#include <PubSubClient.h> // MQTT
#include <ArduinoOTA.h>   // Enable Remote Updates

#include <OpenDevice.h>

const char* ssid = "ap-name";
const char* password = "1";

void setup() {
  ODev.server(""); // MQTT Remote server

  ODev.addDevice("Thing1:LED", 2, Device::DIGITAL);

  WiFi.begin(ssid, password);

void loop() {

Running the Server

The server run as standalone application, and you can also run using docker


site technology
