I have a very frustrating problem – I can not seem to get the user interface to work without the router it is attached to having access to the internet. All things be configured the same – my opensprinkler works great from my Mac on the LAN – but the UI will no longer work if I unplug the WAN wire from the router to the internet. I have no idea’s what is happening. Is it stuck waiting for NTP or something?
I am planning to use in a location with no internet access – any ideas? I can ping the unit just fine.
