@sjarvis The problem is you have the wrong port setup in my mobile app. I suggest deleting config.php and starting over but this time when putting in the IP add :8080 so it looks like this:
I can run Dan interval program (on port 8080) and control my sprinklers just fine from that.
…file_get_contents(http://10.0.1.24/sn0): failed to open stream: HTTP request failed! HTTP/1.1 404 Not Found
The last part shows which IP:Port my mobile app tried to use. It doesn’t show the :8080 which your saying is the port used by interval application.
@PabloS this might be your issue as well. In my mobile app your IP should be followed by :8086.
Edit: You can also edit your config.php and add the :8080/:8086 manually after the IP.
