So I tried this out. I installed the UI files into a local web server I created on my local network. I then configured the OpenSprinkler3.0 according to the FAQ entry for the Java server location.
What I was surprised was now I access the app locally with the WebServer IP and not the OS3 IP. I had been pointing to the local OS3 IP in the past. Why is this? The Web Server did ask me to scan my local network and it found the local OS3 IP. I was just wondering why this changed. Did I do something wrong? BTW – It appears to be working so not really complaining but trying to understand how the local UI hosting is supposed to work now.
