Sounds like an interesting project. But one question about that:
The "Address" is the address of the server, which can be either an IP or DNS for your server.
When connecting from the same network where the Arduino is located, you can just use the Arduino IP address.
How should this work, the only access to the Arduino is over your webservice. So you always need access from the internet to the Arduino-Server. Or is there a way to have the frontend service running on an local webserver (not Arduino).
How is the access to the Arduino protected against unauthorized connections? IMHO the Arduino is not able to do some session-encryption fpr the access from outside.
