Lazy Engineers free MQTT server is now live.
For now the broker and the client supports only the basic functions. Hopefully I will be adding more features in the future. If you feel like you can help in the project development please feel free to join this project on Hackaday or shoot me a message and we can discuss further.
I have also made a Javascript websocket client for testing this broker or other ones, you can give it a try on the following link. http://www.lazyengineers.com/mqtt-websocket/
The broker is hosted on Google Compute Engine and it uses the settings below.
Host: mqtt.lazyengineers.com
Plain Websocket Port: 10452
Plain TCP Port: 1883
SSL TCP Port: 8883
SSL Websocket Port: 9883
Username: lazyengineers
Password: lazyengineers
When I have time I will add some information about installing and testing an MQTT broker on your own machine.
