Getting started

We think open source is key for the Internet of Things, and we want to get you started as simply as possible.

On this page you will find useful resources like videos and presentations given at various conferences, tutorials, as well as a list of server sandboxes you can use to connect your devices.

Connected Greenhouse Tutorial

If you are a Java developer we have a great tutorial for you to get started with Eclipse IoT technology and help you implement an end-to-end solution that will help you connect a greenhouse and associated sensors to the Internet of Things.





You can make use of this MQTT server with client code from the Paho project, the Eclipse MQTT view from Paho, or from one of the other client APIs listed on the downloads page.

Access the server using the hostname and port 1883. You can also access the server using encrypted port 8883
The encrypted port support TLS v1.2, v1.1 or v1.0 with x509 certificates and requires client support to connect.

You can also use MQTT over WebSockets, both plain and secured, using the following connection URIs (respectively): ws:// and wss://

Some live statistics are available via Xively and an HTTP bridge with a list of topics is deployed at This server is running the Open Source Mosquitto broker in its most recently released version.


A CoAP server exposing test resources is available at: coap://, and DTLS-enabled version at coaps://

It should be used by anyone interested in testing a CoAP client implementation against another endpoint, and more generally by anyone interested in understanding the key concepts of the CoAP protocol.

This server is running Eclipse Californium.

Lightweight M2M (LWM2M)

In order to test LWM2M communication scenarios, we host a LWM2M server.

You can make use of this server with the Wakaama project

The LWM2M server is available at: coap:// (both IPv4 and IPv6 are available)
A web interface allows to interact with registered LWM2M clients:

This server is running the Open Source Eclipse Leshan server.
