Hello bl4d3,
at first let me say: Its a great job what you have done! I am watching for a few month to this side and now i am really lucky to see, that you still developing this cool system 
The new function to generate the arduino code is very good and easy. I tried it and it works (right now, only in the browser).
Now i have two questions:
What do you think, how secure is this system when i integrate some arduinos with the code to my house and control them via my phone trough the internet (connect them to my route with dyndns)? Is it possible and good to add a function like &key=xyzXYZ or something like that?
The second question is, what does the checkbox "Send data to remote server?" do (in the arduino-code-generator)?
Thanks a lot and keep going on
On weekend i will try the Android app
