This must have been asked (and answered) before, but after half-an-hour searching I feel relaxed about asking! I am looking to build some code which interfaces to C-Gate. Months ago I did a simple application to switch a light on and off via C-Gate and Sockets. I cannot remember where I found the example code which I used. Now I am looking to get a bit more complex - including having the ability to read values from a 5504GI. Is there somewhere that the C-Gate command set is documented? From looking at my copy of C-Gate, I think I need the "Command and Event Interface Specification". Where can I find that? Thanks
