Do you have a master valve?
Yes. The problem was the system needed a reflash. It works now.
Hi intherain - what do you mean the system needed a reflash? Mine is currently doing the same thing (5 second popup when it cycles to the next zone), but I don’t have a rain sensor. This also just started happening recently. I have a Gen2 with 16 zones.
@Gene, are you aware that Weather Underground has stopped issuing the APIs required by WUFYI? have you found any alternatives to this approach?

You can always use a Raspberry Pi running Weewx and publish to any site you want.
I have this working on a RPi 2 connected via USB to my display. It does drop USB connectivity every now an then, so I have a few scripts monitoring things to make sure all is running.
