I built my opensprinkler several years ago, it has worked fine despite not doing firmware updates that my phone app nagged me about. Today I thought that with daylight savings changing I would get the clock correct and remember that since the controller didn’t have a DST feature I would need to change the timezone to -7:00 from -8:00, I’m in So Ca. I made the change at the controller, rebooted and now I can’t get it to communicate with the UI or the phone. the controller shows that is connected, I use a plug in network extender and it looks like it is communicating on both ends, and I have rebooted many times. Any idea what could have changed? Is it time to update the firmware or will that bring on new issues?
