The Ewon Flexy has been designed to let users write their own code and personalize their Ewon device to suit their demand. 

Several languages can be used depending on what the user is willing to have as a end-result: set up a specific alarm format, create your own I/O server, display tags value in a web app...

The Developer website helps you find which language would be the best one for your projects and proposes concrete examples of applications.
