As of Jan 8, 2017 this issue has been fixed.

Thank you!

-----------------------

It has been brought to our attention that starting Jan-1-2017 the IOS dashboard is showing N/A for all weather information.

We identified the bug and posted am updated IOS app, currently awaiting Apple Store Approval. This bug is actually caused by an Apple IOS locale issue affecting U.S. locales. 

NOTE: This bug will manifest itself only in the 1st week of 2017. 2nd week (After Jan-8) dashboard will start displaying OK. 

This is a dashboard bug and it is not affecting the functionality of the RainMachine device.
