It's not redundant at all, for me this topic is still alive. I just don't have much time at the moment to resolve it.
Thank you for offering a page to use, but I already have a page on a server (my own VPS). The thing is, I don't want the Arduino polling a server all the time. For a real time response to commands send to the Arduino it would need to poll several times per second. This will cause a lot of traffic 24 hrs/day while it only needs to respond to commands maybe 20 times per day. So I need the Arduino to be a server listening all the time. And to be accessible from outside the LAN. And the ideal situation is getting that without the need for port-forwarding. Hence this topic...
Cheers,
A
