I have been working with arduino modules before as field devices. Been working with mega 2560 and Uno with ethernet shields where am able to send the arduino commands to read and write GPIO's as per the application using GET and POST commands. I want to move to the opta for a more industrial touch, as I have been facing mounting, wiring and casing issues for my projects, as some modules are deployed in insane industrial conditions but they still work. This opta device seems to be a game changer, can I run similar sketches on the opta, where I make use of the ethernet for my own field communication. Read an input or control an output from my web app or mobile phone?
